Answer:

4/9 x 15/8 = 5/6

Step-by-step explanation:

Make 8/15 a reciprocal (basically just means to turn the fraction upside down).

Then turn the division sign into a multiplication sign and multiply across, and there you have it!

Answer:

B. Married, widowed, or divorced men have high income jobs. A high income job tends to make an individual more dedicated. This dedication leads a man to get married.

Step-by-step explanation:

A lurking variable is one that is not measured in the given study but it will affect the relationship between the explanatory and response variables.

Now, in this case, we see that divorced or widowed men, are said to earn quite a little more than men that are of the same age who have never been married.

Now, we are told it does not imply that a man can raise his income by getting married.

This means that majority who have high income tend to consider getting married.

Thus, we can infer that having a high income job leads to a man being more dedicated and this leads him to getting married.

Answer:

235

Step-by-step explanation:

first, separate the floor into 3 different rectangles to calculate the area and then add them together.

area of rec=L*B

rec 1: 9*12.5=112.5

rec 2: (13.5-5.5)*(19.5-9-7)=28

rec 3:7*13.5=94.5

Then:

112.5+28+94.5=235

Answer:

KL = 23

KM = 29

Step-by-step explanation:

By applying cosine rule in the given triangle KLM,

cos(∠M) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

cos(52°) = [tex]\frac{LM}{KM}[/tex]

cos(52°) = [tex]\frac{18}{KM}[/tex]

KM = [tex]\frac{18}{\text{cos}52}[/tex]

KM = 29.24

KM ≈ 29

By applying sine rule,

sin(52°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

sin(52°) = [tex]\frac{KL}{29.24}[/tex]

KL = 29.24[sin(52°)]

    = 23.03

    ≈ 23

KL = 23

Answer:

A, B, D

Step-by-step explanation:

Answer:

A, B, D

Step-by-step explanation:

40% is the same as the fraction 4/10.

Compare 4/10 with 3/20 (A):

LCM of 10 and 20 is 20, so make the denominators of all fractions to 20

We now have 8/20 and 3/20

Now you can just simply look at the numerators. 3 is obviously less than 8 so option A is less than 40%

Compare 4/10 with 23/100 (A):

LCM of 10 and 100 is 100, so make all denominators 100

Now compare 40/100 and 23/100

40>23 so 23/100 is less than 40%

Compare 4/10 with 3/5 (C):

We can further reduce 4/10 to 2/5, and conveniently it has the same denoninator as 3/5. 3 is NOT less than 2, so C is ruled out.

Compare 4/10 with 1/8 (D):

LCM of 10 and 8 is 40, so we'll use that as our denominator

We now have 16/40 and 5/40.

5 is less than 16, so we include D in our answer.

Answer:

70 miles per hour

Step-by-step explanation:

Distance = speed * time

speed = distance / time

------------------------------

Total Distance

speed = 62

time = 5

62 * 5 = 310 miles

Distance travelled in first 2 hours

speed = 50

time = 2

50 * 2 = 100 miles

Remaining distance

310 - 100 = 210 miles

Speed to cover 210 miles in 3 hours

distance = 210

time = 3

210/3 = 70 miles per hour

Answer: 70, 130

Step-by-step explanation:

In the given normal distribution with a mean of 100 and standard distribution of 15, 95% of values will fall between 70 and 130 using the Empirical rule of 95%.

Step-by-step explanation:

A normal distribution with a mean of 100 and a standard distribution of 15 is given.

We will find where 95% of data fall in the given normal distribution.

It states that in a normal distribution approximately 95% of observations fall within two standard deviations from the mean on both sides of the normal curve.

The mean in a normal distribution is the center of the normal curve.

The standard deviation in a normal distribution is the distance from the mean to the required point on either side.

We have,

Mean = 100

Standard deviation = 15

Applying the 95% rule we get,

On the right side of the normal curve

Mean + 2 x standard deviation = 100 + 2x 15 = 100 + 30 = 130.

On the left side of the normal curve,

Mean - 2 x standard deviation  = 100 - 2x15 = 100 - 30 = 70.

Thus, we see that by using the Empirical rule of 95%, 95% values will fall between 70 and 130.

Step-by-step explanation:

Answer:

x=37

Step-by-step explanation:

By Vertical Angles Theorem (VAT), (4x+2) is equal to 150º, so then you just subtract 2 from both sides of the equation 4x+2 = 150, to make it 4x = 148, and then divide both sides by 4 to isolate x, and then you get x=37.
