A population has a mean of 300 and a standard deviation of 40. Suppose a sample of size 100 is selected and is used to estimate

bazaltina [42]

Answer:

a: 0.9544 9 within 8 units)

b: 0.9940

Step-by-step explanation:

We have µ = 300 and σ = 40. The sample size, n = 100.

For the sample to be within 8 units of the population mean, we would have sample values of 292 and 308, so we want to find:

P(292 < x < 308).

We need to find the z-scores that correspond to these values using the given data. See attached photo 1 for the calculation of these scores.

We have P(292 < x < 308) = 0.9544

Next we want the probability of the sample mean to be within 11 units of the population mean, so we want the values from 289 to 311. We want to find

P(289 < x < 311)

We need to find the z-scores that correspond to these values. See photo 2 for the calculation of these scores.

We have P(289 < x < 311) = 0.9940

Which statement is true about the flight of 2 rockets?

umka21 [38]

Answer:

The first rocket, g(x), reached its maximum height before the second rocket, h(x).

Step-by-step explanation:

Each equation is in vertex form, so we can read the vertex of the rocket's path from the equation.

y = a(x -h)^2 +k . . . . . . has vertex (h, k)

g(x) has vertex (time, max height) = (4, 170).

h(x) has vertex (time, max height) = (5, 170).

The rockets have the same maximum height (170), but the first rocket, g(x), reaches that height in 4 seconds, one second sooner than the second rocket, h(x).

The first rocket, g(x), reached its maximum height before the second rocket, h(x).

Write an equation that is parallel to the line 2x - 3y = 9 and passes through the point (4, -1).

insens350 [35]

Answer: $y = \frac{2x}{3} - \frac{11}{3}$

Step-by-step explanation:

Equation of the line given ;

$2x - 3y = 9$

To find the slope of the line we will make y the subject of formula , that is

$3y = 2x - 9$

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

Therefore ; the slope = $\frac{2}{3}$

Two lines are said to be parallel if they have the same slope

This means that the slope of the second line = $\frac{2}{3}$

Using the formula $y-y_{1}= m ( x - x_{1} )$ to find the equation of the line , we have

$y - (-1 ) = \frac{2}{3} (x - 4 )$

$y + 1 = \frac{2x}{3} -\frac{2}{3}(4)$

$y + 1 = \frac{2x}{3} - \frac{8}{3}$

$y = \frac{2x}{3}- \frac{8}{3} - 1$

$y = \frac{2x}{3} - \frac{11}{3}$
