If y varies inversely with x
and y is 10 when x is 5,
then what is y when x is 2?

Answers

Answer 1

9514 1404 393

Answer:

  25

Step-by-step explanation:

Inverse variation means ...

  y = k/x

For the given values, we can find k to be ...

  k = xy = (5)(10) = 50

Then for x=2, we have ...

  y = 50/x

  y = 50/2

  y = 25 . . . when x=2

A pyramid has a square base. The ratio of the base edge to the height of the pyramid is 2:9. If the base edge is 8 units, what is the volume of the pyramid?

Answers

The ration of the base edge to the height of the pyramid is 1 : 4.5

In this case the base edge is 8 units so the height would be 36 units.

Volume of the pyramid 1/3 * A * H

Multiply those numbers together and you end up with 96 units ^ 3 as the answer.



Hope this helps you in finding the volume of the pyramid!

I don't understand this math problem, please help

Answers

Answer/Step-by-step explanation:

1. <A = <B (alternate angles theorem)

90° = 2x (substitution)

Divide both sides by 2

90/2 = 2x/2

45 = x

x = 45

2. <3 = <5 (corresponding angles theorem)

½x = 60 (substitution)

Multiply both sides by 2

x = 60*2

x = 120

3. Based on supplementary bangle theorem, sum of supplementary angles = 180°. Therefore:

m<LFG + m<ABC = 180°

2.5x + x + 33 = 180 (substitution)

Add like terms

3.5x + 33 = 180

3.5x = 180 - 33

3.5x = 147

x = 147/3.5

x = 42

3a. m<LFG = 2.5x

Plug in the value of x

m<LFG = 2.5(42)

m<LFG = 105°

3b. m<ABC = x + 33

Plug in the value of x

m<ABC = 42 + 33

m<ABC = 75°

In a normal distribution, 68% of the data fall within how many standard
deviations of the mean?
A. Two standard deviations
B. One standard deviation
C. It cannot be determined from the given information.
D. Three standard deviations

Answers

B, my teacher just taught us this :)

In a normal distribution of data, 68% of the data fall within one standard deviations of the mean.

What do you mean by normally distributed data?

Normally distributed data is the distribution of probability which is symmetric about the mean.

The mean of the data is the average value of the given data.The standard deviation of the data is the half of the difference of the highest value and mean of the data set.

According to the empirical rule, also known as 68-95-99.7 rule, the percentage of values that lie within an interval with 68%, 95% and 99.7% of the values lies within one, two or three standard deviations of the mean of the distribution.

[tex]P(\mu - \sigma < X < \mu + \sigma) = 68\%\\P(\mu - 2\sigma < X < \mu + 2\sigma) = 95\%\\P(\mu - 3\sigma < X < \mu + 3\sigma) = 99.7\%[/tex]

Here the mean of distribution of X is [tex]\mu[/tex]  and standard deviation from mean of distribution of X is [tex]\sigma[/tex].

Thus, in a normal distribution of data, 68% of the data fall within one standard deviations of the mean.

Barbara charges $3.50, plus $2.25 for each hour she babysits. If Barbara charges $21.50, how many hours does she babysit?

Answers

Answer:

8 hours

Step-by-step explanation:

The equation is 2.25X + 3.50 = 21.50

X represents the unknown amount of hours she worked. 2.25 is the cost per hour. 3.50 is the fee she charges for every gig. That fee only happens once a gig so naturally it wasn't the number x was placed with.

2.25X + 3.50 = 21.50

2.25X + 3.50 - 3.50 = 21.50 - 3.50

2.25X = 18

2.25X = 18

2.25 2.25
