Use the slop-intercept form y=mx + b to find the slope m.
m=5

A supermarket offers a delivery service. If a customer pays $9 per month, each delivery costs just $2. Write an equation that sh

Rzqust [24]

The linear function that models the total cost for x deliveries is:

$y(x) = 2x + 9$

-------------------

A linear function has the following format:

$y = mx + b$

In which

m is the slope, that is, the rate of change.
b is the y-intercept, that is, the value of y when x = 0.

In this problem:

Fixed cost of $9 per month, $b = 9$ .
Cost of $2 for each delivery, thus $m = 2$ .

The function for the total cost for x deliveries is:

$y(x) = 2x + 9$

Refer to the previous exercise. The researchers wanted a sufficiently large sample to be able to estimate the probability of pre

Maru [420]

Answer:

The large sample n = 117.07

Step-by-step explanation:

Step(i):-

Given that the estimate error (M.E) = 0.08

The proportion (p) = 0.75

q =1-p = 1- 0.75 =0.25

Level of significance = 0.05

Z₀.₀₅ = 1.96≅ 2

Step(ii):-

The Marginal error is determined by

M.E = $\frac{Z_{0.05} \sqrt{p(1-p)} }{\sqrt{n} }$

$0.08 = \frac{2 X \sqrt{0.75(1-0.75)} }{\sqrt{n} }$

Cross multiplication , we get

$\sqrt{n} = \frac{2 X \sqrt{0.75(1-0.75)} }{0.08 }$

√n = $\frac{2 X0.4330}{0.08} = 10.825$

squaring on both sides , we get

n = 117.07

Final answer:-

The large sample n = 117.07

Find the measurement of arc JL PLLLLLLSSSS HELP 100 points

aalyn [17]

Answer:

108

Step-by-step explanation:

Hey There!

So the arc is equal to its corresponding angle

We are given the angle of KL which is 30 so all we need to do is find the length of arc JK

The angles given and the missing angle are supplementary angles meaning that they will add up to equal 180

so we subtract the given angles from 180 to find the missing angle

180-30-72=78

Now we just add arc JK and arc Kl

30+78=108

so arc JL is equal to 108
