Answer: $2.90

Step-by-step explanation: So you get 10% if you just move the decimal one place to the left so that would be 10%= 1.45 and then you mutiply that by 2 since 10% times 2 is 20% and that is your answer

Answer:

b

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

Following Pythagorean Theorom, we know a^2 + b^2 = c^2. We know b and c.  a^2 + 5^2 = 13^2.

a^2 + 25 = 169

a^2 = 144

a = √144

a = 12

So, the answer is 12, which means we pick D

Answer: fifty six tenths

Step-by-step explanation:

7/10 x 8 → turn 8 into a fraction → 7/10 x 8/1 → multiply the numerators → 7 x 8 = 56 → multiply the denominators → 10 x 1 = 10 → and get your answer, 56/10

Answer:

The correct answer is E, 551.6 square feet.

Step-by-step explanation:

I think we can assume that the two ends are perfect semi-circles, although that's not clearly specified.

In that case, the total area we have is that of a 15x25 foot rectangle, plus a circle with a diameter of 15ft.

So lets work that out.  The rectangle is easy, as the area is just width times height. 15 ft * 25 ft is 375 ft²

The area of a circle is defined as πr².  We're given the diameter, which is twice the radius, so the collective area of the two ends would be π × 7.5² which equals π × 56.25, or approximately 176.7 square feet.

Now we just need to add those together:

375 + 176.7 = 551.7

The difference in answer will be due to rounding, so we know that the correct answer is E, despite their answer being rounded incorrectly.

Answer: A

Step-by-step explanation:

Ron's conclusion that the observed frequency will eventually be closer to the expected frequency is reasonable and supported by probability theory.

It is a branch of mathematics that deals with the occurrence of a random event.

The law of large numbers states that as the sample size increases, the observed frequency of an event will converge to the expected frequency based on the theoretical probability of the event. In this case, the expected frequency of pulling a blue pen is 3/6 or 1/2, which is based on the theoretical probability of pulling a blue pen.

Although Ron pulled a blue pen only 1 time in 4 trials, it is important to note that he replaced the pen each time.

This means that each trial was independent of the others, and the probability of pulling a blue pen in each trial remained the same at 3/6 or 1/2.

As Ron continues to repeat the trials and increase the sample size, the observed frequency of pulling a blue pen will become closer and closer to the expected frequency of 1/2, as predicted by the law of large numbers.

Therefore, Ron's conclusion that the observed frequency will eventually be closer to the expected frequency is reasonable and supported by probability theory.

Answer:

Step-by-step explanation:

−3/4÷2/−8=?

In the second fraction, move the negative sign from the denominator to the numerator and the value remains the same.

The equivalent equation is

−3/4÷ −2/8=?

Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.

Take the reciprocal of the second fraction by flipping the numerator and denominator, leaving the negative sign on the numerator, and changing the operation to multiplication. Then the equation becomes

−3/4× −8/2=?

For fraction multiplication, multiply the numerators and then multiply the denominators to get

−3× −8/4×2= 24/8

Since 24 divided by 8 equals 3 then,

24/8 =3

Therefore:

−3/4÷ 2/−8= 3
