Answer:

Slope: -2/3

Y Intercept: 0,-3

Step-by-step explanation:

To find the slope, use the formula (y1-y2)/(x1-x2)

(1-(-1))/(-6-(-3))

-2/3

So the slope is: -2/3

If the slope is 3/2, then the using the formula of y=mx+b, we can find the y intercept (b)

y = -2/3x + b

insert any point of x and y

-1 = -2/3(-3)+b

-1=-2+b

so b = -3

thus, the Y intercept is 0,-3

andriy [413]

Answer:

Sue must score 94 on the final test to earn a B.

Step-by-step explanation:

There are five tests in total.

Sue's average on the first four tests is 84.

If after the final test, she scores X, she will have a B on average of five tests.

Vending machines can be adjusted to reject coins above and below certain weights. The weights of legal U.S. quarters have a norm
tigry1 [53]

Answer: The percentage of legal quarters will be rejected by the vending machine = 2.275%

Step-by-step explanation:

Given: The weights of legal U.S. quarters have a normal distribution with a mean of 5.67 grams and a standard deviation of 0.07 gram.

Let x be the weights of legal U.S. quarters .

Required probability: P(x5.81)

=P(\dfrac{x-\mu}{\sigma}\dfrac{5.81-5.67}{0.07})\\\\=P(z2)\approx0.02275    \ \ \ [By\  P-value\ calculator]

The percentage of legal quarters will be rejected by the vending machine = 2.275%

Convert 60ft/s to km/h can someone tell me how to work this problem out?
stellarik [79]
3280.839895 ft = 1 km
60 ft = 60/3280.839895 = 0.018288 km

60 ft/s = 0.018288 km/s = 0.018288 x 60 x 60 = 65.8368 km/h

is it
A. 3 friends took 1 slice each (total is 3 slice) or
B. 3 friends took 1 slice total

if A, go to AAAAAA
if B. to to BBBBB


AAAAAAAAAA
3 slices taken
fraction is parts out of whole
what is left
left=original-taken
taken=3
original=8
8-3=5
5=left
fraction is 5/total=5/8


BBBBBB
taken=1
fraction is parts out of whole
what is left
left=original-taken
taken=1
original=8
8-1=7
7=left
fraction is 7/total=7/8





if 3 slices taken total then 5/8 left
if 1 slice taken totl then 7/8 left
