Answer:

32 degree

Step-by-step explanation:

total pentagon exterior angles = 360 degrees

2x + 3x + 71 + 85 + 44 = 360

5x + 200 = 360

5x = 160

x = 32 degree

Answer:

x = 32

Step-by-step explanation:

Recall that the sum of all external angles of a polygon always adds up to 360°

hence

71° + 85° + 44° + 3x° + 2x° = 360

200° + 5x° = 360°

5x° = 360° - 200°

5x° = 160°

x = 160/5

x = 32

When the function f(x) = 4(2)x is changed to f(x) = 4(2)x − 13, what is the effect? (5 points)

PtichkaEL [24]

Answer:

If x = o then f(0) = 4(2) * 0 = 0

If f(x) = 4(2) 0 - 13

then f(x) = -13 at x = 0

A study was conducted to compare the proportion of drivers in Boston and New York who wore seat belts while driving. Data were c

allochka39001 [22]

Answer:

a) The test statistic is $z = -2.51$

b) The pvalue is 0.0060.

Step-by-step explanation:

Question a:

Ha: pB < pNY

This means that the alternate hypothesis is rewritten as:

$H_a: p_{B} - p_{NY} < 0$

While the null hypothesis is:

$H_0: p_{B} - p_{NY} = 0$

The test statistic is:

$z = \frac{X - \mu}{s}$

In which X is the sample mean, $\mu$ is the value tested at the null hypothesis and s is the standard error

pB = 0.581, pNY = 0.832

This means that $X = 0.581 - 0.832 = -0.251$

0 is tested at the null hypothesis:

This means that $\mu = 0$

Standard error = 0.1

This means that $s = 0.1$

Test statistic:

$z = \frac{X - \mu}{s}$

$z = \frac{-0.251 - 0}{0.1}$

$z = -2.51$

The test statistic is $z = -2.51$

Question b:

The pvalue is the probability of finding a proportion less than -0.251, that is, a difference of at least 0.251, which is the pvalue of Z = -2.51.

Looking at the z-table, Z = -2.51 has a pvalue of 0.0060

The pvalue is 0.0060.
