Step-by-step explanation:

Grant made an error in simplifying the expression.

The error in Grant's work is that he simplified the expression incorrectly. Let's go through the correct steps to simplify the expression:

So, the correct simplified expression is -1.05.

The most appropriate level of measurement for monthly temperatures (in Fahrenheit or Celsius) is the interval scale. The interval scale accommodates differences in measurements but doesn't provide meaningful ratios. The other levels of measurement (nominal, ordinal, ratio) are not suitable for such kind of temperature data.

The level of measurement most appropriate for monthly temperatures, such as 63° f, 67° f, 71° f, 75° f, and 79° f, is the interval scale. The interval level of measurement pertains to data where differences make sense, but ratios do not. This means that while we can say one temperature is higher than another, we cannot say one is a certain multiple of another. For instance, we can confidently say 80° F is 20 degrees hotter than 60° F, but we can't say it is 'twice as hot'.

Temperatures are measured using scales like Celsius (C) and Fahrenheit (F), which both logically fall under this level because 0 is not the absolute lowest temperature.

The other levels of measurement include nominal, ordinal, and ratio. The nominal scale is for categorical data, the ordinal scale includes an order of values, and the ratio scale allows for meaningful fractions or ratios of values. In the case of temperatures, these other levels do not apply. They require a 0 to be absolute—representing non-existence of the attribute—like in the Kelvin temperature scale, which the given temperatures are not.

Answer:

The correct answer is option B.  44°

Step-by-step explanation:

From the figure we can see a circle, and an angle subtended.

The angle from an arc subtended n the other arc of a circle is half the angle made by the arc in center.

To find the measure of m<ABC

Here the central angle of arc AC is 88°,

<ABC is half the central angle made by arc AC

Therefore m<ABC = 88/2 = 44°

The answer is A.  Check the picture attached.

Step-by-step explanation:

Answer:

graph of h(x)= a slope of 2, and the y-intercept is 0.

graph of g(x)= a slope of 1, and a y-intercept of 6.

graph of f(x)= a slope of 1, and a y-intercept of -6.

Step-by-step explanation:

The equation would be h(x)=(x-6)+(x+6) which is also equal to h(x)= 2x if you combine like terms. f(x) and g(x) equations are pretty straight forward.

Answer:

[tex]h(x)=2x[/tex]

Answer:

sin θ/2=5√26/26=0.196

Step-by-step explanation:

θ ∈(π,3π/2)

such that

θ/2 ∈(π/2,3π/4)

As a result,

0<sin θ/2<1, and

-1<cos θ/2<0

tan θ/2=sin  θ/2/cos θ/2

such that

tan θ/2<0

Let

t=tan θ/2

t<0

By the double angle identity for tangents

2 tan θ/2/1-(tanθ /2)^2  = tanθ

2t/1-t^2=5/12

24t=5 - 5t^2

Solve this quadratic equation for t :

t1=1/5 and

t2= -5

Discard t1 because t is not smaller than 0

Let s= sin θ/2

0<s<1.

By the definition of tangents.

tan θ/2= sin θ/2/ cos θ/2

Apply the Pythagorean Algorithm to express the cosine of θ/2 in terms of s. Note the cos θ/2 is expected to be smaller than zero.

cos θ/2 = -√1-(sin θ/2)^2 = - √1-s^2

Solve for s.

s/-√1-s^2 = -5

s^2=25(1-s^2)

s=√25/26 = 5√26/26

Therefore

sin θ/2=5√26/26=0.196....

Answer:

C = 3n+20

Step-by-step explanation:

C= The Cost

n= the number of rides

So if you get on 2 rides

that would be $6

because 3x2=6

or 3+3

and just add in the 20 to get in

so the sum is

26 if you were to get on 2 rides

The total cost of a day at the amusement park, combining both the fixed admission fee of $20 and the variable cost of rides at $3 each, can be represented by the equation c = 3n + 20. Here, 'c' signifies the total cost and 'n' is the number of rides.

In this problem of an amusement park charging a $20 admission fee and $3 for each ride, we need to find an equation that can be used to determine c, the total cost of a day at the amusement park, based on n, the number of rides.

Given that the admission fee is a fixed cost of $20 and each ride costs $3, these elements can be combined into an equation where the total cost (c) is equal to the cost of each ride multiplied by the number of rides (3n), plus the fixed cost of admission ($20).

Therefore, the correct equation as per the given conditions is c = 3n + 20.

Answer:

90 sq inches

Step-by-step explanation:

The lateral area is the side area of the pyramid. In this case, there are 3 sides because the base is a triangle.  Since the base is an equilateral triangle, all sides are of equal dimensions.  So, the sides of the pyramid are also all of the same size, area.

We then just have to figure out the area of one of the side triangles, then multiply it by 3 to get the total lateral area of that pyramid.

We know how to calculate the area of a triangle: A = (b * h)/2

In this case, b = 5 in, h = 12 in. So,

TA = (5 * 12)/2 = 60 / 2 = 30

Each side triangle has an area of 30 sq inches.

LA = 3 * TA (since there are 3 sides)

LA = 3 * 30 = 90 sq inches

Answer:

he function is negative for all real values of x where –6 < x < –2 (True)

Step-by-step explanation:

(x+2) can be written as

x + 2 = 0

x = -2

(x+6) can be written as

x + 6 = 0

x = -6

Both of these can be written as -6 < x < -2

1) he function is positive for all real values of x where x > –4.

(All values are between -2 and -6 and they are negative therefore this statement is false.)

2) True (explained above)

3) The function is positive for all real values of x where x < –6 or x > –3.

(x>-2 includes -3 but x>-3 does not include -3 therefore, this is false.)

4) The function is negative for all real values of x where x < –2. (It is not negative for all values as there is a limit between -2 and -6.)

Answer:

(-4, -4)

Step-by-step explanation:

You have to put this in vertex form by completing the square in order to determine the vertex.  Begin by setting the quadratic equal to 0 then moving the 12 over by subtraction:

[tex]x^2+8x=-12[/tex]

The rules are to take half the linear term, square it, and add it to both sides.  Our linear term is 8.  Half of 8 is 4, and 4 squared is 16.  So we add 16 to both sides:

[tex](x^2+8x+16)=-12+16[/tex]

During this process we have created a perfect square biomial on the left. We will state that, along with simplifying on the right:

[tex](x+4)^2=4[/tex]

Now we will move the 4 back over and set it back to equal y:

[tex](x+4)^2-4=y[/tex]

And from this you can see that the coordinates of the vertex are (-4, -4)

Answer:

(b + 2)^2

Step-by-step explanation:

b^2 + 4b + 4

It's perfect square: a^2 + 2ab + b^2 = (a + b)^2

So

b^2 + 4b + 4 = (b + 2)^2

Answer:

(b + 2)(b + 2)

Step-by-step explanation:

Factor the polynomial.  

b^2 + 4b + 4

Sum of 4 which product is 4

Sum: 1 + 3 = 4

      2 + 2 = 4

Product: 1 × 4 = 4

             2 × 2 = 4

We use 2 × 2 because it sum is the same as the product of 4. Because 2 and 4 are perfect square so we have:

b² + 4b + 4  splitted  as

(b + 2)(b + 2) or (b + 2)²

The correct answer option is B. Construct a line perpendicular to XP through point A.

Step-by-step explanation:

We are given an incomplete figure of construction of a perpendicular line and we are to determine whether which of the given answer options is the next step in the construction.

From the given marks, we can deduce that a perpendicular line to XY is being constructed, passing through P.

So the next step must be to construct a line perpendicular to XP through point A to complete the construction.

The next step in the construction is:

From the given construction we may observe that the construction is of a line segment perpendicular to line segment XY.

The steps of construction are as follows:

1) Take a line segment XY.

2) Take a compass and open the  compass more than half the length of XY and then make the arc by keeping the compass one's at X and then at Y.

3) The point where the arc meet draw a straight line such that it pass through the point P.

4) AP will be the perpendicular line to XY and point P is the mid-point of XY.

Answer:

D, 4.62

Step-by-step explanation:

e = √(1 - b²/a²)

To solve for a, first square both sides:

e² = 1 - b²/a²

Then subtract 1 from both sides:

e² - 1 = -b²/a²

Multiply both sides by -1:

1 - e² = b²/a²

Multiply by a²:

(1 - e²) a² = b²

Divide by 1 - e²:

a² = b² / (1 - e²)

Take the square root:

a = b / √(1 - e²)

So the answer is D.

When b = 4 and e = ½:

a = 4 / √(1 - (½)²)

a = 4 / √(1 - ¼)

a = 4 / √¾

a = 8 / √3

a ≈ 4.62

Step-by-step explanation:

From the charts we can see that there 8120 students that are Undergraduates and 2610 students that are Graduates. We add this up to get the total number of students in the University 10730. This Gives us the following fraction of Graduates in the University.

[tex]\frac{2610}{10730} =  0.243[/tex]

[tex]0.243*100  = 24.3[/tex]  ...we multiply by 100 to turn the decimal into a percent

We can then round to the nearest percentage which is 24%.

So the probability of the randomly selected student being a graduate is 24%.
