What is the slope intercept equation for this graph someone answer the question pls

Answer:

k=2 or 5/4

Step-by-step explanation:

8k^2-26k+20=0

2(4k²-13k+10)=0

(4k²-13k+10)=0/2

4k²-8k-5k+10=0

4k(k-2)-5(k-2)=0

(k-2)(4k-5)=0

either.

k=2

or

k=5/4

Answer:

The runner with a mean running time of 6.2

Step-by-step explanation:

The value range parameters of the three runners are;

The mean running time of the runner, A = 6.2

The mean running time of the runner, B = 7.4

The mean running time of the runner, C = 6.9

The interquartile range of the runner, A = 1.1

The interquartile range of the runner, B = 0.02

The interquartile range of the runner, C = 0.08

Whereby the number of running times for the 3 runners is large, and with the assumption that distribution of the mean is normal, we have

The mean = The mode of  the data

Therefore, the minimum, and maximum running time of the runners are;

Runner A;

Minimum running time = 6.2 - 1.1 = 5.1

Maximum running time = 6.2 + 1.1 = 7.3

Runner B;

Minimum running time = 7.4 - 0.02 = 7.38

Maximum running time = 7.4 + 0.02 = 7.42

Runner C;

Minimum running time = 6.9 - 0.08 = 6.82

Maximum running time = 6.9 + 0.08 = 6.98

The fastest runner has the lowest running time;

Therefore, the fastest runner is runner A with a mean running time of 6.2  with a minimum running time of 5.1

hes right the answer would be 50+200n so 200

Step-by-step explanation:

Cos (angle) = Adjacent/Hypotenuse

Cos 20° = 12/x

Answer:

Actually, 20 divided by 2 1/3 equals 8.57 repeating (8.571428...), which can be rounded to 8.57 to two decimal places.

To see why, we can convert the mixed number 2 1/3 to an improper fraction:

2 1/3 = (2 * 3 + 1) / 3 = 7/3

Then, we can rewrite the division as a fraction and simplify:

20 / (7/3) = 20 * (3/7) = 60/7 = 8.571428...

So, 20 divided by 2 1/3 is approximately 8.57.

Answer:

3/8

Step-by-step explanation:

Answer:

3/8

Step-by-step explanation:

You divide fractions by flipping it around and multiplying it...

The reciprocal of 2 is 1/2

So 3/4*1/2=3/8

in fraction form: 144 and 3/8

Answer:

18x ≥ 160

Step-by-step explanation:

Ashley has two jobs: mowing lawns and babysitting. She earns $10 per hour mowing lawns (x) and $8 per hour babysitting (y). And she wants to earn at least $160 per week.

Let the number of hours = x

At least = Greater than or equal to

Slope intercept form

= y = mx + c

y = $160

Hence

10x + 8x ≥ 160

18x ≥ 160

Answer:

Step-by-step explanation:

because they both are alternate exterior angles

1. If a shift in demand and/or supply has taken place, identify the change and list the determinant.

Answer:

The answer is below

Step-by-step explanation:

The demand has increased or shifted to the right.

The supply did not change.

The determinant for this situation is the increase in demand

However, with the price increment, the will be an increase in supply.

Answer:

<A=135°

now

3x+6+x+2=180

sum of two opposite angle of the cyclic quadrilateral is 180

4x=180-8

x=172/4=43°

<A=3×43+6=135° is your answer

Answer:

you may have done this wrong

Step-by-step explanation:

5x-3=121

add 3 on both sides

5x=-36<------what you did was wrong

you should have ended up with...

5x=124

divide by 5 on both sides

x=24.8

Complete Question

A set of magical wand prices are normally distributed with a mean of 50 dollars and a standard deviation of 4 dollars. A blackthorn wand has a price of 45.20. What proportion of wand prices are lower than the price of the blackthorn wand? You may round your answer to four decimal places

Answer:

0.1151

Step-by-step explanation:

We solve using z score formula

z = (x-μ)/σ, where

x is the raw score = $45.20

μ is the population mean = $50

σ is the population standard deviation = $4

We are solving for x < 45.20

Hence:

z = 45.20 - 50/4

z = -1.2

Probability value from Z-Table:

P(x<45.20) = 0.11507

Approximately to 4 decimal places = 0.1151

Therefore, the proportion of wand prices that are lower than the price of the blackthorn wand is 0.1151
