Papessa [141]

Answer:

87.08% percentage of families spend more than $4000 annually on food and drink

Step-by-step explanation:

Given -

average annual expenditure on food and drink for all families is $5700

Mean $(\nu)$ = 5700

standard deviation $(\sigma )$ = 1500

Let X be the no of families spend annually on food and drink

percentage of families spend more than $4000 annually on food and drink =

$P(X > 4000)$ = $P(\frac{X - \nu }{\sigma }> \frac{ 4000 - 5700}{1500})$

= $P(Z > - 1.13)$ Using $(Z = \frac{X - \nu }{\sigma })$

= 1 - $P(Z$

= 1 - .1292

= .8708

= 87.08%

I need help with this question

Black_prince [1.1K]

Answer:

Step-by-step explanation:

The slope-intercept form is found by solving that equation for y.

If $y-3=\frac{1}{2}(x-1)$ then

$y-3=\frac{1}{2}x-\frac{1}{2}$ and

$y=\frac{1}{2}x-\frac{1}{2}+3$ and

$y=\frac{1}{2}x-\frac{1}{2}+\frac{6}{2}$ so

$y=\frac{1}{2}x+\frac{5}{2}$

The answer you have chosen is the correct one! Good job!
