What is the measurement of JL?

Answers

Answer 1

Answer:

Answer:

180 - 90 - 62 = 28

17 /sin90 = x/sin28

x = 7.98

x = 8.00

So JL measures 8

Answer 2

Answer: The measurement of JL is 8

What sort of information can you get from conditional frequencies that you couldn't get by just looking at the relative frequencies?

Answers

Answer:

Conditional frequencies offer more specific information to analyse certain data set.

Step-by-step explanation:

A conditional frequency is a type of relative frequency which involves a condition to be defined.

For example, the conditional frequency of having a house given that the person is female. Notice that this example shows the condition "being female", so the conditional frequency would be all females who own a house.

On the other hand, the relative frequency is just a ratio between the frequency of the data and the total number of data. It's doesn't includes a condition to be defined, that's the difference.

Therefore, conditional frequencies offer more specific information to analyse certain data set.

The average high temperature in Anchorage, Alaska, in January is 21°F with a standard deviation of 10°. The average high temperature in Honolulu in January is 80°F with a standard deviation of 8°. In which location would it be more unusual to have a day in January with a high of 57°F?

Answers

Answer:

In Honolulu it be more unusual to have a day in January with a high of 57°F

Step-by-step explanation:

Given,

The average high temperature in Anchorage, Alaska,

$\mu_1$ = 21° F,

Having standard deviation,

$\sigma_1$ = 10°,

Thus, the z-score for the high temperature of 57° F in alaska,

$z_1=(57-\mu_1)/(\sigma_1)$

$=(57-21)/(10)$

$=3.6$

By the z-score table the probability of the high temperature of 57°F in Alaska = 0.99984 = 99.984 %

Now, the average high temperature in Honolulu is,

$\mu_2=80^(\circ)$

Having standard deviation,

$\sigma_2=8^(\circ)$

Thus, the z-score for the high temperature of 57° F in Honolulu,

$z_2=(57-\mu_2)/(\sigma_2)$

$=(57-80)/(8)$

$=-2.875$

By the z-score table the probability of the high temperature of 57° in Honolulu = 0.00205 = 0.205 %

Since, a probability is unusual if it is less than 5 %,

Hence, In Honolulu it be more unusual to have a day in January with a high of 57°F.

It would be more odd in Honolulu.

The area of a square is found by squaring one of its sides, (A = s2). A certain square has an area of z2 + 18z + 81. Factor the trinomial to find a side of the square.a. side = z + 27
b. side = z + 18
c. side = z + 9

Answers

A = s²
A = z² + 18 z + 81
z² + 18 z + 81 = z² + 9 z + 9 z + 81 = z ( z + 9 ) + 9 ( z + 9 ) =
= ( z + 9 ) ( z + 9 ) = ( z + 9 )²
Answer:
C ) side = z + 9

Answer:

option c is correct.

side = z+9

Step-by-step explanation:

Area of a square(A) is given by:

$A = s^2$
