Answer:

Step-by-step explanation: 122 degrees

Answer:

6 ; 10

18 ; 162

Step-by-step explanation:

Recall :

Rate of change = Slope = Rise / Run = (y2 - y1) / (x2-x1)

2nd point is (1, 7)

3rd point is (2, 13)

Rate of change = (13 - 7) /(2 - 1)  = 6 /1 = 6

3rd and 4th point :

(2, 13)

(3, 23)

Rate of change = (23 - 13) / (3 - 2) = 10 /1 = 10

PART B:

(2, 11) ; (3, 29)

Rate of change = (29 - 11) / (3 - 1) = 18 /1 = 18

(4, 83)

(5, 245)

Rate of change = (245 - 83) /  (5-4) = 162 / 1 = 162

Step-by-step explanation:

Answer: 0

Step-by-step explanation:

So the slope of a line is equal to rise over run, or the change in x over the change in y. We can solve for the change in x and the change in y by finding their differences. For the math, we use the formulas y2 - y1/x2 - x1. Filling in this formula we get, (5-5)/(3-13), which is equal to 0/10. Because 0 divided by anything is 0, the answer here is 0.

Answer:

Hence  Mr Drew will get 20 pieces of a Quarter

Step-by-step explanation:

From the question we are told that:

Money changed [tex]m= 5[/tex]

Number of coins [tex]N=20p[/tex]

Generally the equation for coin change into x is mathematically given by

 [tex]x=\frac{m}{N}[/tex]

 [tex]x=\frac{5}{20}[/tex]

 [tex]x=\frac{1}{4}[/tex]

Therefore oin change into x is given as

 [tex]x=\frac{1}{4}[/tex]

Hence  Mr Drew will get 20 pieces of a Quarter

Answer:

x = 2

Step-by-step explanation:

The measure of minor arc FD is 51x + 1

The measure of major arc FD is 360 - (51x + 1)

m<E = ½[m(major arc FD) - m(minor arc FD)]

36x + 5 = ½[360 - (51x + 1) - (51x + 1)]

72x + 10 = 360 - 51x - 1 - 51x - 1

174x = 348

x = 2

Answer:

1. The sample size is greater than 30.

Step-by-step explanation:

z test is a statistical test, used for hypothesis testing, for verifying statistical significance of a population parameter (from sample statistic)

It is used when in case when the sample size is large, ie greater than 30. It is used when the data follows normal distribution. In case of small sample size, ie less than 30, t test is used.

The set of parametric equations representing the skater's jump is:

x = 52t

y = 5 + 16t²

We have,

Let's denote the time as t.

Horizontal motion:

The skateboarder's horizontal velocity remains constant throughout the jump, so the horizontal position (x) can be represented as:

x = vt

where v is the horizontal velocity, which in this case is 52 ft/s.

Vertical motion:

The vertical position (y) can be determined using the equations of motion under constant acceleration.

The skateboarder experiences acceleration due to gravity (g) acting downward.

The initial vertical position is 5 ft, and the initial vertical velocity is

0 ft/s.

Using the equation of motion:

[tex]y = y_0 + vy_0t + 0.5gt^2[/tex]

Substituting the given values:

y = 5 + 0t + 0.5(32)t²

y = 5 + 16t²

Thus,

The set of parametric equations representing the skater's jump is:

x = 52t

y = 5 + 16t²

Step-by-step explanation:

if y=3x^2

if x is 1 y is 3 because if you substitute x for 1, 1^2 = 1, And 3•1 = 3

if x is 2 y is 12 because if you substitute x for 2, 2^2 = 4 and 3•4 =12

Keep going using this formula, You can go into the negatives by substituting x for a negative number aka -1 or -2

Answer:

1/32

Step-by-step explanation:

There is a 1/8 chance of spinning green on the first spinner and a 1/4 cnace of spinning blue on the second spinner. To find the probability of both spinners landing on the desired color, multiply their probabilities.

1/8 * 1/4 = 1/32 chance of landing on green and then blue.

Answer:

152 square inches

Step-by-step Explanation:

To answer this, please look at the picture below. We can find the area by separating and combine the value of areas after calculating three values for each areas. (Notice that when we separate them, we get three rectangles which we can use the formula of width × length)

We should get 80+48+24 which add up to 152.

Answer:

x = 1/2

Step-by-step explanation:

8x-(4x-3)=5

Distribute the minus sign

8x -4x +3 = 5

Combine like terms

4x+3 =5

Subtract 3 from each side

4x+3-3 = 5-3

4x = 2

4x/4 = 2/4

x = 1/2

Answer:

The Interquartile range is 10.

Step-by-step explanation:

First, we will need to find the mean, the mean of this sequence is 16, you will now need to find quartile 1 and quartile 3. Quartile 1 is 13, and quartile 3 is 23. Lastly, subtract Quartile 3 and Quartile 1 will be the answer.

So, 23-13=10

The Answer will be 10, the interquartile range is 10.

Answer:

231.746 km

Step-by-step explanation:

Formula: [tex]distance = speed[/tex] × [tex]time[/tex]

Solution: To solve for distance use the formula for distance

Rate and speed are similar since they both represent some distance per unit time like miles per hour or kilometers per hour. If rate r is the same as speed s, r = s = d/t. You can use the equivalent formula d = rt which means distance equals rate times time.

Firstly, convert the time from hours to minutes

2 hr 15 min = 2.25 hr

or 2.25 hr = 135 min

Now, use the formula:

135 × 64 = 8640

In km, the distance traveled is 231.74

Answer:

Clearly they are not equivalent because division will get you a smaller number ( except when decimals are in used or special cases ) as an answer and division times the number that will oppositely get you a bigger number ( again, except the decimal or special cases )
