Answer:

a) 31/33
b) $124
c) $930

Step-by-step explanation:

a) You want the ratio ...

(Salena's earnings)/(Drew's earnings)

It is convenient to fill in the numbers from the first line of the table:

(Salena's earnings)/(Drew's earnings) = 31/33

b) Salena's earnings in 4 days will be double her earnings in 2 days.

4 days' earnings = 2×$62 = $124

c) Salena's earnings in 30 days will be 10 times her earnings in 3 days.

30 days' earnings = 10×$93 = $930

_____

<em>Alternate solution</em>

You can go to the trouble to write an equation for Salena's earnings (s) in terms of the number of days (d). That would be ...

s = 31d

Then you can fill in d=4 or d=30 to find her earnings for 4 or 30 days. For this problem, enough information is given in the table that shortcuts can be used, simplifying the problem immensely.

I dont get this please help

Viktor [21]

Step-by-step explanation:

the side lengths of the base (the ground triangle) are equal. that means every ground side length is 8 in.

and that also makes the 3 triangles of the side areas of the pyramid equal.

so, for the surface area of the pyramid we need to calculate the area of one side area triangle, multiply it by 3 (as we have 3 side areas) and add the area of the ground triangle.

the area of a triangle is

baseline × height / 2

so, for a side area triangle we get

8 × 14 / 2 = 8×7 = 56 in²

all 3 side areas together are then

3×56 = 168 in²

the ground area triangle is then

8 × 6.9 / 2 = 4 × 6.9 = 27.6 in²

so, the total surface area of the pyramid is

168 + 27.6 = 195.6 in²

performance determine the slope and the y-intercept given the following linear functions. 1.f(x)=3x-10

Monica [59]

Answer:

Slope: 3

Y-Intercept: -10

Step-by-step explanation:

This equation is in slope-intercept form, it is written as y = mx + b where m is the slope and b is the y-intercept. This means 3 is the slope and -10 is the y-intercept.

Let n1equals50, Upper X 1equals30, n2equals50, and Upper X 2equals10. Complete parts (a) and (b) below. a. At the 0.05 leve

Viefleur [7K]

Answer:

Null hypothesis: $p_{1} = p_{2}$

Alternative hypothesis: $p_{1} \neq p_{2}$

$z=\frac{0.6-0.2}{\sqrt{0.4(1-0.4)(\frac{1}{50}+\frac{1}{50})}}=4.082$

$p_v =2*P(Z>4.082)=4.46x10^{-5}$

So the p value is a very low value and using any significance level for example $\alpha=0.05$ always $p_v$ so we can conclude that we have enough evidence to reject the null hypothesis, and we can say the the proportion 1 is significantly different from proportion 2.
