Answer:

Step-by-step explanation:

The angle at E is 90 degrees.

All tangents of a circle always meet the radius at a 90 degree angle.

90 + 67 + G = 180o    All triangles have 180 degrees. Combine left.

157 + G = 180o           Subtract 157 from both sides.

157 - 157 + G + 180 - 157

G = 23

Answer:

(x,y)=(2,8)

Step-by-step explanation:

-6x = -4 -y

-7x = -22 +y

Rearranging the above equations

-6x +y +4 =0 => eq(1)

-7x -y +22 =0 => eq(2)

Adding eq(1) and eq(2)

-6x +y +4 =0

-7x -y +22 =0

___________

-13 x +26 =0

-13x = - 26

x= -26/-13

x= 2

Putting value of x in eq (1)

-6(2) + y +4 =0

-12 +y+4 =0

y-8=0

y=8

So, values of x and y are 2 and 8

(x,y)=(2,8)

Answer:

If my parents are going to pay the 5%, then, they will pay: $2979.

I will need to save $62.06 each month to accomplish my goal.

Step-by-step explanation:

I'm going to a 4-year college that will cost $14895/year.

It means that I will need to pay: 14895*4 = $59.580

If my parents are going to pay the 5%, then, they will pay: $2979.

Now, if I want to save my total contribution for all four years, and I have four years to accomplish  the goal, then:

Then, if I have 4 years to pay it. It means I have 4*12 = 48 months.

Then I will need to save $2979./48 = $62.06 each month to accomplish my goal.

The student needs to pay $744.75 yearly, which is 5% of the annual college cost. To save this amount over four years, they need to save $62.06 each month for 48 months.

The student needs to calculate their contribution to the college expenses. First, we need to find 5% of the annual cost of $14,895.00 to determine the student's yearly contribution:

Yearly Contribution = $14,895.00 * 0.05 = $744.75 per year.

Next, to calculate the total contribution over four years:

Total Contribution = 4 * $744.75 = $2,979.00.

To save the total amount in four years, we divide the total contribution by the number of months in four years (48 months):

Monthly Savings = $2,979.00 / 48 = $62.06.

Therefore, the student needs to save $62.06 each month for 48 months to cover their share of college expenses.

Answer:

62°

Step-by-step explanation:

The 2 shown angles form a straight angle and sum to 180°, that is

7x + 20 + 4x + 6 = 180

11x + 26 = 180 ( subtract 26 from both sides )

11x = 154 ( divide both sides by 11 )

x = 14

the acute angle = 4x + 6 = (4 × 14) + 6 = 56 + 6 = 62°

A is the answer to this question

Find the vertex: -4x^2 + 16x - 7​

Vertex = ( x, f(x)).

x = -b/2a

x = -16/2(-4)

x = -16/-8

x = 2

f(x) = -4x^2 + 16x - 7

Let x = 2

f(2) = -4(2)^2 + 16(2) - 7

f(2) = -4(4) + 32 - 7

f(2) = -16 + 32 - 7

f(2) = 16 - 7

f(2) = 9

Vertex = (2, 9)

Answer:

C(x) = 2

Step-by-step explanation:

The graph of the average cost is shown in the attached image.

Note that, as is to be expected, when the number of booklets produced x increases, then the average cost per booklet decreases.

To calculate the expected cost of producing a booklet when x is very large, look at the graph.

Note that when x = 2 then the average cost is equal to 4, then when x = 5 the average cost is 2.5.

In this way, the bigger x is made, the more the cost approaches 2.

Therefore it can be said that

[tex]\lim_{x \to \infty}C(x)= 2[/tex]

Finally, the expected average cost when the number of booklet  produced is very large is C (x) = 2

Answer:

D. Opposite angles are congruent

With option A, we can see that it is clearly wrong, in a parallelogram, only the opposite sides are congruent, if all of the sides are congruent then the shape is more likely to be a square or a rhombus.

With option B, only the opposites angles are congruent. If all four angles are congruent, that will be more likely to be true when we consider a square or a rectangle.

With option C, it is also wrong, unless the shape is a rhombus, square or rectangle.

That leaves us with the last option which is D.

Answer:

So,  the experimental probability of tossing heads using lynn and dawn's results is 2/5

Step-by-step explanation:

No of times the coin is tossed = 30

No of times head came = 12

Probability of tossing heads = No of times head came / No of times the coin is tossed

                                              = 12/30

                                              = 4/10

                                              = 2/5

So,  the experimental probability of tossing heads using lynn and dawn's results is 2/5

Answer:

Step-by-step explanation:

Percent decrease =

(difference in prices)/(original price) × 100

(2.89 - 2.82)/2.89 × 100

= (0.07)/2.89 ×100 ≈ 2.4%

The price of unleaded gas has increased by 2.2% from yesterday to today. This percentage was calculated by finding the price increase ($0.06), dividing it by yesterday’s price ($2.79), and multiplying by 100. The result was then rounded to the nearest tenth of a percent.

To find the percentage increase in the price of a gallon of unleaded gas, you first need to find the difference in the price. In this case, today's price is $2.85 and yesterday's price was $2.79, so the difference is $2.85 - $2.79 = $0.06.

Then, to find the percentage increase, you divide this difference by the original price (which is yesterday's price) and multiply by 100 to turn it into a percentage. So, percentage increase = ($0.06 / $2.79) * 100 = 2.15053.

Finally, you round this to the nearest tenth of a percent, which gives you 2.2%. So, the price of unleaded gas has increased by 2.2% from yesterday to today.

Answer:

Dividing mixed numbers is very similar to multiplying mixed numbers. You just add one step—after changing the divisor into an improper fraction, you then find its reciprocal and multiply. ... First step: Write the whole number and the mixed number as improper fractions.

Step-by-step explanation:

Dividing mixed numbers is essentially similar to dividing whole numbers, with an extra step of converting mixed numbers into improper fractions. The core concepts remain the same but it extends division into fractions.

Dividing mixed numbers is related to dividing whole numbers because the fundamental concepts remain the same. In dividing whole numbers, we take a number (dividend) and distribute it into equal parts. For instance, dividing 6 by 2, we are distributing 6 into 2 equal parts, which will give us 3 in each part.

Similarly, when dividing mixed numbers, we proceed in the same manner. However, it adds an extra step of converting mixed numbers into improper fractions first before proceeding with the division. For example, when dividing 2 1/2 by 1 1/2, we would first convert these into improper fractions and then proceed with the division as we would do with whole numbers.

Therefore, the concept for dividing mixed numbers is essentially an extension of the concept for dividing whole numbers.

[tex]y = 2 \sin( \theta) - 3[/tex]

EXPLANATION

The parent function

[tex]y = \sin( \theta) [/tex]

can be shifted down by 3 units to obtain

[tex]y = \sin( \theta) - 3[/tex]

Also, when the basic sine function is stretched vertically by a factor of 2, the equation becomes,

[tex]y = 2 \sin( \theta) [/tex]

Therefore, a vertical shift down 3 units and stretch factor of 2 gives the equation:

[tex]y = 2\sin( \theta) - 3[/tex]

The correct choice is E.

Answer:

The value of the mean reflects both the number and the value of cases. is false

Step-by-step explanation:

The incorrect statement about the mean is that it's pulled in the direction of the hump in a skewed distribution. In fact, the mean is influenced by every value in the data set, including outliers, and if a distribution is skewed, the mean is pulled towards the tail, not the hump.

The statement that is false about the mean is: 'The mean is pulled in the direction of the hump in a skewed distribution'. Rather, it's the median that stays closer to the 'hump' in a skewed distribution. The mean is affected by every value in the data set, including outliers. If a distribution is skewed, the mean will be pulled in the direction of the skew, which could be towards the tail, not the hump. For example, in a right-skewed distribution with values 1, 2, and 100, the mean would be 34.33, which is closer to the outlier (100) rather than the hump around 1 and 2.
