Which of the following equations is modeled by the graph.

Sergio [31]

Answer:

a = 50t

Step-by-step explanation:

The graph goes through (0,0) so the y intercept is 0

a=5t

a=50t

a=50 + t not it

a=10t

The slope is y/x since the y intercept is 0

m = 50/1 = 50

The equation for the line is

y = 50x+0

y = 50x

Using the variables given

a = 50t

$v = \frac{4}{3} \times \pi \times ({ \frac{8}{2} })^{3} \\$

$v = \frac{4}{3} \times 3 \times {4}^{3} \\$

$v = {4}^{4}$

$v = {2}^{8}$

$v = 256 \: \: {cm}^{3}$

The weight of oranges growing in an orchard is normally distributed with a mean weight of 6.5 oz. and a standard deviation of 1.

sergey [27]

Add 3 standard deviations above and below the mean to get the range in which 99.7% of the data in a normal distribution will fall
6.5 + 4.5 = 11
6.5 - 4.5 = 2
So 2 to 11 ounces would be the interval
