Step-by-step explanation:

$18 {v}^{2} - 15v - 18 \\ = 3(6 {v}^{2} - 5v - 6) \\ = 3 \{6 {v}^{2} - 9v + 4v - 6 \} \\ = 3 \{3v(2 {v} - 3) +2( 2v - 3) \} \\ = 3(2v - 3)(3v + 2)$

zysi [14]

Solution:

We are given that

Shaneese is buying peanuts and cashews.

he has $12 to spend.

peanuts cost $3 per pound and cashews cost $4 per pound.

she buys x pounds of peanuts and y pounds of cashews.

The equation that represents the amount of each is $3x + 4y = 12.$

Now we have been asked to find the y-intercept.

To find the y-intercept , we need to set x=0

when x=0, equation becomes

$3*0 + 4y = 12.$

$0 + 4y = 12.$

$4y = 12.$

Divide both the sides by 4 we get

$y = 3$

Hence the y-intercept is 3.

-hope this helped have a good rest of your day :)

Step-by-step explanation:

Calculate the area of the base (which is a circle) by using thee equation πr² where r is the radius of the circle. Then, multiply the area of the base by the height of the cylinder to find the volume. ... Since the volume V of a right circular cylinder is given by V = πr²h.

Suppose a normal distribution has a mean of 62 and a standard deviation of 4. What is the probability that a data value is betwe

Anon25 [30]

Answer:Given a normal distribution with μ = 62 and σ = 4., calculate the 68-95-99.7 rule, or three-sigma rule, or empirical rule ranges

Calculate Range 1:

Range 1, or the 68% range, states that 68% of the normal distribution values lie within 1 standard deviation of the mean

68% of values are within μ ± σ

μ ± σ = 62 ± 4.

62 - 4. <= 68% of values <= 62 + 4.

58 <= 68% of values <= 66

Calculate Range 2:

Range 2, or the 95% range, states that 95% of the normal distribution values lie within 2 standard deviations of the mean

95% of values are within μ ± 2σ

μ ± 2σ = 62 ± 2(4.)

62 - 2 x 4. <= 95% of values <= 62 + 2 x 4.

62 - 8 <= 95% of values <= 62 + 8

54 <= 95% of values <= 70

Calculate Range 3:

Range 3, or the 99.7% range, states that 99.7% (virtually ALL) of the normal distribution values lie within 3 standard deviations of the mean

99.7% of values are within μ ± 3σ

μ ± 3σ = 62 ± 3(4.)

62 - 3 x 4. <= 99.7% of values <= 62 + 3 x 4.

62 - 12 <= 99.7% of values <= 62 + 12

50 <= 99.7% of values <= 74
