Answer:

B. ∠6, D. ∠2, E. ∠3, F. ∠4

Step-by-step explanation:

∠2, ∠3, ∠4 & ∠6 are exterior angles as they present outside the triangle. Here, only ∠1 & ∠5 are present in the interior of the triangle.

Hope it helps ⚜

Each car in a rental fleet is either red or white, and there are 75 cars total. There are three more white than twice the number

professor190 [17]

Number of red cars = x
Number of white cars = y

x + y = 75
y + 3 = 2x

x + y = 75
y = 75 - x

(75 - x) + 3 = 2x
78 = 3x
26 = x

y + 3 = 2(26)
y + 3 = 52
y = 49

There are 49 white cars.

According to the Central Limit Theorem, which statements(s) are TRUE. There may be more than 1 correct answer. A. An increase in

Liono4ka [1.6K]

Answer:

Options A, B and C are correct.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean $\mu = p$ and standard deviation $s = \sqrt{\frac{p(1-p)}{n}}$

From the Central Limit Theorem, we have that:

The larger the sample size, the closer to the normal distribution the distribution of sample means is.

No matter the sample size, the mean is the same.

The larger the sample size, the smaller the standard deviation.

The smaller the sample size, the larger the standard deviation.

So the correct options are:

A, B, C

Ermias and Jeremiah both leave the bookstore at the same time, but in opposite directions. If Jeremiah travels 8 mph faster than

Pie

Answer:

Jeremiah travels at 26.667 mi/hr and Ermias travels at 18.667 mi/hr.

Step-by-step explanation:

Say Ermias' speed is 's' and Jeremiah's is 'v'

distance = rate * time

distance = ( v * time) + ( s * time)

v = s + 8

240mi = ( (s+8) * 8 ) + ( s + 8)

240 = (8s +64) + s + 8

240 = 9s + 72

240 - 72 = 9 s

168 = 9 s

18.6666667 = s

v = 18.6666667 + 8

v = 26.6666667

Allisa [31]

Answer:

t= 0

Step-by-step explanation:

Using the rules of logarithms

log x + log y = log(xy)

$log_{b}$ 1 = 0

Given

$log_{x}$ a + $log_{x}$ $\frac{1}{a}$ = t ,then

$log_{x}$ (a × $\frac{1}{a}$ ) = t

$log_{x}$ 1 = t , thus

t = 0
