Answer:

B)-4

Step-by-step explanation:

y=mx+c

sub in a point and gradient/slope to get c

-7=3(-1)+c

-7=-3+c

-7+3=c

c=-4

y=3x-4

if u looking for the y intercept make x=0

y=3(0)-4

y=-4

The two tables give the number of pints of red and blue paint that are used to make different amounts of two shades of purple pa

ValentinkaMS [17]

The two highlighted rows show that for the same amount of blue, Purple #1 uses more red than Purple #2.

This means that Purple #1 is a redder shade of purple than Purple #2.

Purple #2 is a bluer shade of purple than Purple #1.

Step-by-step explanation:

The two highlighted rows show that for the same amount of blue, Purple #1 uses more red than Purple #2.

Making blue's quantity as 3 parts for purple #1 implies red part becomes 1.5 to maintain the ratio 1:2

Purple #1 has 1/3 parts red and 2/3 parts blue. Purple #2 has 1/4th part red and 3/4th part blue.

Hence, Purple #1 is a redder shade of purple than Purple #2.

From the above explanation, Purple #2 is a bluer shade of purple than Purple #1.

Sure hopes this helps you :)

To estimate the mean score μ μ of those who took the Medical College Admission Test on your campus, you will obtain the scores o

Juliette [100K]

Answer: 0.4667

Step-by-step explanation:

According to 68–95–99.7 rule , About 99.7% of all data values lies with in 3 standard deviations from population mean ( $\mu$ ).

Here , margin of error = 3s , where s is standard deviation.

As per given , we have want our sample mean $\overline{x}$ to estimate μ μ with an error of no more than 1.4 point in either direction.

If 99.7% of all samples give an $\overline{x}$ within 1.4 , it means that

$3s=1.4$

Divide boths ides by 3 , we get

$s=0.466666666667\approx0.4667$

Hence, So $\overline{x}$ must have 0.4667 as standard deviation so that 99.7 % 99.7% of all samples give an $\overline{x}$ within 1.4 point of μ .

bekas [8.4K]

Answer:

$\displaystyle 15\:feet\:wide \\ 32\:feet\:long$

Step-by-step explanation:

{2 + 2w = l

{94 = 2w + 2l

94 = 2w + 2[2 + 2w]

94 = 2w + 4 + 4w

94 = 4 + 6w

- 4 - 4

_________

$\displaystyle \frac{90}{6} = \frac{6w}{6}$

$\displaystyle 15 = w$ [Plug this back into both equations above to get the length of 32 feet]; $\displaystyle 32 = l$

I am joyous to assist you anytime.
