Find a. Round to the nearest tenth.
Kazeer [188]

9514 1404 393

Answer:

  21.8 cm

Step-by-step explanation:

A useful way to write the Law of Sines relation when solving for side lengths is ...

  a/sin(A) = b/sin(B)

Then the solution for 'a' is found by multiplying by sin(A):

  a = sin(A)(b/sin(B)) = b·sin(A)/sin(B)

__

We need to know the angle A. Its value is ...

  A = 180° -75° -31.8° = 73.2°

Then the desired length is ...

  a = (22 cm)sin(73.2°)/sin(75°) ≈ (22 cm)(0.9573/0.9659)

  a ≈ 21.8 cm

_____

I like to use the longest side and largest angle in the equation when those are available. That is why I chose 75° and 22 cm.

Answer:

-19

Step-by-step explanation:

Take the second term and subtract the first term to find what we are adding (or subtacting ) each time

-7 -(-3) =

-7+3

-4

We are subtracting 4 each time

Subtract 4 from the next term

-15 -4 = -19

The next term is -19

A newspaper article indicated that 43 percent of cars with black seats are white, 46 percent of cars with black seats are blue,
NNADVOKAT [17]

Complete question :

A newspaper article indicated that 43 percent of cars with black seats are white, 46 percent of cars with black seats are blue, 7 percent of cars with black seats are red, and 4 percent of cars with black seats are black. A test was conducted to investigate whether the color of cars with black seats was consistent with the newspaper article. A random sample of cars of these colors was selected, and the value of the chi-square test statistic was x = 8.2. Which of the following represents the p-value for the test?

A) P(x2 ≥ 8.2) = 0.08

B) P(x2 ≥ 8.2) = 0.04

C) P(x2 ≤ 8.2) = 0.96

D) P (x2 = 8.2) = 0.00

E) The p-value cannot be calculated because the sample size is not given.

Answer:

P(χ² ≥ 8.2) = 0.04

Step-by-step explanation:

We need to obtain the degree of freedom ;

Number of levels, k - 1

k = (white, blue, red, black) = 4

df = k - 1= 4 - 1 = 3

The test statistic, χ² = 8.2

The Pvalue is the probability of a Chisquare statistic with 3 degree of freedom is equal to or more extreme than the statistic value, 8.2

Using the Pvalue for calculator from Chisquare statistic, at 3 degree of freedom

Pvalue(8.2, 3) = 0.042

Hence,

P(χ² ≥ 8.2) = 0.04
