Answer:

118°

Step-by-step explanation:

Since it is an isosceles triangle, two angles must be the same.

Also angles in a triangle add up to 180° and from this we can deduce that

x + ( 31 + 31 ) = 180

( Simplify )

x + 62 = 180

( - 62 from both sides )

x = 118°

Answer:

2.150 = 2.15

2 +15/10 > 2.15

2 + 0.015 < 2.15

215/100 = 2.15

Step-by-step explanation:

2.150 = 2.15, because 2.15 can be rewritten as 2.150.

2 +15/10=2+1.5=3.5

2 +15/10 > 2.15

3.5 > 2.15

2 + 0.015 < 2.15

2.015 < 2.15

215/100 = 2.15

2.15 = 2.15

Answer:

The correct answer option is y = -4.

Step-by-step explanation:

We are to find the equation of the mid-line for the following function:

[tex]y=3cos(x-\pi)-4[/tex]

[tex]3 cos((x - \pi ) - 4 = 3 cos(x) - 4[/tex] because [tex]cos(x-\pi) = cos(x)[/tex]

[tex]-1 \leq cos(x) \leq 1[/tex]

[tex]-3 \leq 3cos(x) \leq 3[/tex]

[tex]-3-4 \leq 3 cos(x)-4 \leq 3-4[/tex]

[tex]-7 \leq 3 cos(x)\leq-1[/tex]

The range is -7 to -1 so the midpoint is [tex]\frac{-7-1}{2} =-4[/tex]

Therefore, the equation of the mid-line for the given function is y = -4.

Answer:

2.8 ·  10^(-9)

Step-by-step explanation:

I'd suggest you do this problem through two separate multiplications:

First, 0.4·0.7 = 0.28, or 2.8 · 10^(-1)

Second, 10^(-6) · 10^(-2) = 10^(-8), and so the final result is

2.8 · 10^(-1) · 10(-8)  =  2.8 ·  10^(-9)

Please note:  negative exponents (such as -9, above) should be enclosed in parentheses for added clarity.

Answer:

Center a processes it faster

Step-by-step explanation:

Center B math: 2 tons as pounds is 4000 pounds.

4000/7=571.43 pounds a day

571.43/24=23.81 pounds a hour

23.81 pounds per hour is less than 100 pounds an hour. so center a is the faster one.

Answer:

Center A process aluminium faster

Because

Center A process 8.4 Tons of aluminium per week while center B processes 2 tons per week

Step-by-step explanation:

Topic: Unit Conversion

Given

Center A Rate of Processing Aluminium

A = 100 pounds per hour

Center B Rate of Processing Aluminium

B = 2 tons per week

To solve this question, the following assumptions will be made

Having said that, the first step is to make conversions.

We either convert pounds to tons or tons to pounds.

Converting Center A Rate of Processing Aluminium from Pounds to Tons

1 Pound = 0.0005 Tons

So, 100 Pounds = 0.0005 * 100

100 Pounds = 0.05 Tons.

So, Center A Rate of Processing Aluminium is 0.05 Tons per hour

Before we make comparison, both must be in the same unit.

i.e. either in Tons per hour or Tons per units.

Converting Center A Rate of Processing Aluminium from Tons per hour to Tons per week

There are 24 hours a day;

So, Center A Rate of Processing Aluminium is 0.05 Tons/hr* 24 hr/day

Converting Center A Rate of Processing Aluminium is 1.2 Tons / day

There are 7 days a week;

So, Center A Rate of Processing Aluminium is 1.2 Tons/ day * 7 days / week

Converting Center A Rate of Processing Aluminium is 8.4 Tons / week

At this point, we have the following

Center A Rate of Processing Aluminium = 8.4 Tons / week

Center B Rate of Processing Aluminium = 2 tons per week

By Comparison,

8.4 Tons per week is greater than 2 tons per week; So, Center A process aluminium faster

Answer:

In mathematics, a parabola is a plane curve that is mirror-symmetrical and is approximately U-shaped.

Answer:

Step-by-step explanation:

a symmetrical open plane curve formed by the intersection of a cone with a plane parallel to its side. The path of a projectile under the influence of gravity ideally follows a curve of this shape.

A parabola is a two-dimensional, mirror-symmetrical curve, which is approximately U-shaped when oriented as shown in the diagram below, but which can be in any orientation in its plane. It fits any of several superficially different mathematical descriptions which can all be proved to define curves of exactly the same shape.

Answer:

AB = 17.3 cm

Step-by-step explanation:

We require to find the measure of ∠A then use the cosine ratio to calculate AB

sum the parts of the ratio 3 + 2 = 5 parts, then

90° ÷ 5 = 18° ← value of 1 part of ratio

∠A = 2 × 18° = 36°, thus

cos36° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{14}{AB}[/tex]

Multiply both sides by AB

AB × cos36° = 14 ( divide both sides by cos36° )

AB = [tex]\frac{14}{cos36}[/tex] ≈ 17.3 cm

For this case, we must find the value of "x" so that the given expression is equal to 8.

That is to say:

[tex](\sqrt [5] {8 ^ 3}) ^ x = 8[/tex]

We apply "ln" to both sides of the equation to remove the exponent variable:

[tex]ln ((\sqrt [5] {8 ^ 3}) ^ x) = ln (8)\\xln (\sqrt [5] {8 ^ 3}) = ln (8)\\xln (\sqrt [5] {512}) = ln (8)[/tex]

We rewrite 512 as:

[tex]512 = 32 * 16 = 2 ^ 5 * 16\\xln (\sqrt [5] {2 ^ 5 * 16}) = ln (8)[/tex]

By definition of power properties we have:

[tex]\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}[/tex]

So:

[tex]xln (2 \sqrt [5] {16}) = ln (8)[/tex]

We clear x:

[tex]x = \frac {ln (8)} {ln (2 \sqrt [5] {16})}[/tex]

In decimal form, [tex]x = 1.6[/tex] periodic number

ANswer:

[tex]x = \frac {ln (8)} {ln (2 \sqrt [5] {16})}\\x = 1.6\ periodic\ number[/tex]

Answer:71.4

Step-by-step explanation:140*51%

The answer is 71.4 because 51% =.51 and .51•140= 71.4

When you say Percent, you really mean per 100. So percentage is the result you get when multiplying a quantity by a percent. To find 80% of 20, we can use the following expression:

[tex]20\times \frac{80}{100}=16[/tex]

That is the product of 80 and 20 divided by 100, which is 16.

Answer:

The correct answer is

80% of 20 = 16

Step-by-step explanation:

points to remember

x% of y is given by

(x/100) * y

To find 80% of 20

Let 'x' be the 80% of 20 then we can write,

x = (80/100) * 20

x = (8/10) * 20

 = 8 * 2 = 16

Therefore 80% of 20 is 16

The correct answer is 16

Answer:

enlarge the picture 7 times by inches

To enlarge Tonya's picture by a factor of 7, the length of 4 1/5 inches is multiplied by 7 to get an enlarged length of 29 2/5 inches.

Tonya has a small picture with a length of 4 1/5 inches. To enlarge the picture by a factor of 7, we need to multiply the original length by 7. First, we convert 4 1/5 inches to an improper fraction: 4 1/5 = (4 * 5 + 1)/5 = 21/5. Next, we multiply by 7: (21/5) * 7 = 21 * 7 / 5 = 147/5 inches. To convert it to a mixed number, we divide 147 by 5 which equals 29 with a remainder of 2, leading to a mixed number of 29 2/5 inches. Thus, the enlarged picture has a length of 29 2/5 inches.

Equation of Area of Triangle = 1/2 x b x h

Find the base by counting the boxes across the bottom.

Find the height by counting the boxes from the base (bottom) to highest point on the triangle.

Insert those numbers into the equation and you get your answer.

To find the area of a triangle on a coordinate plane, you can use the formula: Area = 1/2 * base * height. The base can be any side of the triangle, and the height is the perpendicular distance from the base to the opposite vertex. We can calculate the lengths of the base and height by using the coordinates of the triangle's vertices.

To find the area of a triangle on a coordinate plane, we can use the formula: Area = 1/2 * base * height. The base can be any side of the triangle, and the height is the perpendicular distance from the base to the opposite vertex. We can calculate the lengths of the base and height by using the coordinates of the triangle's vertices.

For example, if the coordinates of the vertices are (x1, y1), (x2, y2), and (x3, y3), we can find the length of the base by calculating the distance between (x1, y1) and (x2, y2). Then, we can find the height by calculating the distance between (x3, y3) and the line containing the base. Finally, we substitute the values of the base and height into the formula to find the area.

Suppose the coordinates of the triangle are (1, 2), (4, 6), and (7, 2). We can find the base and height as follows:

Now, substitute the values into the formula: Area = 1/2 * base * height = 1/2 * 5 * 2 = 5 units^2. Therefore, the area of the triangle is 5 square units.

The 95% confidence interval for the mean score is:

[tex]\mu[/tex] ∈ [tex](67.73,\ \ 84.67)[/tex]

Step-by-step explanation:

We want to estimate the population mean, that is, the average score of all the subjects.

An estimator for the population mean μ is [tex]{\displaystyle {\overline {x}}}[/tex]

Since the sample size is [tex]27 <30[/tex] then we use the  statistic  [tex]t_{\frac{\alpha}{2}}[/tex]  with [tex]27-1 = 26[/tex] degrees of freedom

The confidence interval for the mean is:

[tex]({\displaystyle {\overline {x}}} + t_{\frac{\alpha}{2}}\frac{S}{\sqrt{n}},\ \ {\displaystyle {\overline {x}}} - t_{\frac{\alpha}{2}}\frac{S}{\sqrt{n}})[/tex]

Where

[tex]{\displaystyle {\overline {x}}}=76.2[/tex] is the average score of the sample

[tex]S=21.4[/tex] is the standard deviation of the sample

[tex]n= 27[/tex] is the sample size

[tex]t_{\frac{\alpha}{2}} = 2.056[/tex] for a confidence level of 95% and 26 degrees of freedom

Then confidence interval is

[tex](76.2 + 2.056\frac{21.4}{\sqrt{27}},\ \ {76.2 - 2.056\frac{21.4}{\sqrt{27}})[/tex]

[tex](76.2 + 8.467,\ \ 76.2 - 8.467)[/tex]

[tex]\mu[/tex] ∈ [tex](67.73,\ \ 84.67)[/tex]

The 95% confidence interval for the mean score of attitudes towards public transportation is (68.13, 84.27), calculated using the formula for a confidence interval.

In this scenario, we would use the formula for a 95% confidence interval, which is the sample mean ± (1.96 * (standard deviation / √n)). In this case, n is 27 (the sample size), the sample mean is 76.2, and the standard deviation is 21.4.

Firstly, calculate the standard error by dividing the standard deviation by the square root of n:

SE = 21.4 / √27 ≈ 4.12

Then multiply the standard error by 1.96:

1.96 * SE ≈ 1.96 * 4.12 ≈ 8.07

Finally, add and subtract this value from the sample mean to get the confidence interval:

76.2 ± 8.07 gives an interval of (68.13, 84.27).

So, we can be 95% confident that the true population mean of attitudes towards public transportation lies between 68.13 and 84.27.
