Multiply each number by 3

Answer:

[tex] \frac{168}{120} = \frac{21}{15} = \frac{7}{5} = 1.4[/tex]

So the percent increase is 40%.

The percentage increase from 120 to 168 is 40%. This is calculated by finding the increase (48), dividing it by the original number (120), and multiplying the result by 100.

The question asks for the percentage increase from 120 to 168. To find this, we first determine the increase in the number, which is 168 - 120 = 48. The percentage increase is then calculated by dividing this increase by the original number (120 in this case), and then multiplying the result by 100 to get the percentage. So, the calculation would be (48/120) * 100 = 40. Therefore, the percentage increase from 120 to 168 is 40%.

(b) Similar to part (a), the closest probability to 0.37 is 0.3707. The corresponding z-value for this probability is -0.31 (since we want the probability for z less than 0). Therefore, z_0 = -0.31.

(c) The probability of P(-z_0 <= z <= z_0) = 0.92 represents the area under the standard normal distribution curve between -z_0 and z_0. From the standard normal distribution table, we can find the z-value that corresponds to the area of 0.46 (half of 0.92) as 1.75. Thus, we can write:

z_0 = 1.75/2 = 0.875

(d) P(z > z_0) = 0.095 represents the area under the standard normal distribution curve to the right of z_0. From the standard normal distribution table, we can find the z-value that corresponds to the area of 0.905 (1-0.095) as 1.645. Thus, we can write:

(b) The probability of drawing a card below a 2 is 4/52 or 1/13. This is because there are only 4 cards (A, K, Q, J) that are above a 2, and there are 52 total cards in the deck.

(c) To find the probability that a card is both above a jack and below a 2, we need to find the number of cards that satisfy both conditions. There are no cards that satisfy both conditions, so the probability is 0/52 or 0.

(d) To find the probability that a card is either above a jack or below a 5, we need to find the number of cards that satisfy either condition. There are 48 cards above a jack and 20 cards below a 5 (A, 2, 3, 4), but we need to subtract the overlap (cards that are both above a jack and below a 5), which is only 2 (A and 2). So the total number of cards that satisfy either condition is 48 + 20 - 2 = 66. The probability is then 66/52 or 33/26, which simplifies to 1 7/26.

The specific heat of the brass can be calculated using the formula:

Q = mcΔT

where Q is the heat transferred, m is the mass of the brass, c is the specific heat of the brass, and ΔT is the change in temperature.

First, calculate the heat transferred from the brass to the water:

Qbrass = mcΔT = (125 g)(c)(100 °C - 35 °C) = 9375c J

Next, calculate the heat transferred from the water to the brass:

Qwater = mcΔT = (76 g)(4.184 J/g. °C)(35 °C - 25 °C) = 3191.84 J

Since the heat lost by the brass is equal to the heat gained by the water:

Qbrass = Qwater

9375c J = 3191.84 J

c = 0.34 J/g. °C

Therefore, the specific heat of the brass is 0.34 J/g. °C.

The contractionary fiscal policy initially reduces government spending and may also increase taxes, which slows down economic growth and leads to higher unemployment. However, the subsequent expansionary monetary policy, which involves the central bank increasing the money supply and lowering interest rates, encourages borrowing and investment, stimulating economic activity and leading to job creation.

The concentration of the H2SO4 solution is 0.0395 M.

To find the concentration of the H2SO4 solution, we can use the balanced equation and the concept of stoichiometry. From the equation, we can see that 1 mole of H2SO4 reacts with 2 moles of NaOH.

First, find the moles of NaOH used in the titration:
moles of NaOH = volume of NaOH (L) × concentration of NaOH (M)
moles of NaOH = 0.02595 L × 0.657 M = 0.01704 moles

Now, using the stoichiometry of the balanced equation, we can find the moles of H2SO4:
moles of H2SO4 = moles of NaOH ÷ 2 = 0.01704 moles ÷ 2 = 0.00852 moles

Next, find the concentration of the H2SO4 solution:
concentration of H2SO4 (M) = moles of H2SO4 ÷ volume of H2SO4 (L)
concentration of H2SO4 (M) = 0.00852 moles ÷ 0.2157 L = 0.0395 M

If we have access to the data, we can use statistical tests such as the Shapiro-Wilk test or the Kolmogorov-Smirnov test to determine if the data is normally distributed. However, since we only have information about the population average and effect size, we cannot directly test for normality.

However, based on the central limit theorem, we can assume that if the sample size is large enough (typically >30), the distribution of the variable of interest will be approximately normal. In this case, since we do not have information about the sample size, we cannot definitively say if the data is normally distributed.

J = 2K - 6 (Jade is 6 years less than twice Kevin's age)

J - 2 = 3(K - 2) (two years ago, Jade was three times as old as Kevin)

We can use the first equation to substitute for J in the second equation:

(2K - 6) - 2 = 3(K - 2)

Simplifying this, we get:

2K - 8 = 3K - 6

K = 2

So Kevin is currently 2 years old, and Jade is:

J = 2K - 6 = 2(2) - 6 = -2

This doesn't make sense as an age, so there may be an error in the problem statement or in our solution method.

Let's use algebra to solve for Amanda's current age, which we can call A. Then we can use that to find her age 3 years from now. We have:

L = 3A - 2 (Len is 2 less than 3 times Amanda's age)

L + 3 = 2(A + 3) + 7 (three years from now, Len will be 7 more than twice Amanda's age)

Substituting the first equation into the second, we get:

(3A - 2) + 3 = 2(A + 3) + 7

Simplifying this, we get:

A = 5

So Amanda is currently 5 years old, and her age 3 years from now will be:

A + 3 = 5 + 3 = 8

Let's use algebra to solve for Faith's current age, which we can call F. Then we can use that to find Janna's and William's ages. We have:

J = 2F (Janna is twice as old as Faith)

W = F + 9 (William is 9 years older than Faith)

J - 3 = 3(F - 3) - 9 (three years ago, Janna was 9 less than 3 times Faith's age)

Substituting the first two equations into the third, we get:

(2F) - 3 = 3(F - 3) - 9

Simplifying this, we get:

F = 6

So Faith is currently 6 years old, Janna is:

J = 2F = 2(6) = 12
