3, -12, 48, …; 6th term

1 answer:

6 0

Pattern : Multiply by -4 to get to the next number
3 x (-4) = -12
-12 x (-4) = 48
To get to the 6th term : 3 x (-4)^5 = 3 x (-1024) = -3072

The department of public safety has an old memo stating that the number of accidents per week at a hazardous intersection varies

ELEN [110]

Answer:

P-value = 0.1515

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 2.2

Sample mean, $\bar{x}$ = 2

Sample size, n = 52

Alpha, α = 0.05

Population standard deviation, σ = 1.4

First, we design the null and the alternate hypothesis

$H_{0}: \mu =2.2\\H_A: \mu < 2.2$

We use one-tailed(left) z test to perform this hypothesis.

Formula:

$z_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }$

Putting all the values, we have

$z_{stat} = \displaystyle\frac{2 - 2.2}{\frac{1.4}{\sqrt{52}} } = -1.03$

Now, we calculate the p-value from the normal standard table.

P-value = 0.1515

ruslelena [56]

Answer:

3052.08 m³

Step-by-step explanation:

$\boxed{volume \: of \: sphere = \frac{4}{3}\pi {r}^{3} }$

Given that the radius is 9m, r=9.

Volume of sphere

$= \frac{4}{3} (3.14)(9^{3} )$

= 3052.08 m³
