So it is C because when you use rise over run, then you just look at the line were the line crosses trough the caskets and then you see that rise is 1 and run is two so it is 1/2 but if you convert the fraction into a decimal, the. It will be 0.5. The b is we’re the line goes trough the y-axis. So y=1/2+4 but you have to convort it into a decimal and it will be C y=0.5x+4. You welcome

When money is spent on goods and services, those who receive the money also spend some of it. The people receiving some of the t

Bad White [126]

Solution :

If $S_n$ is the total spending generated after n transactions, then $a_n$ is the spending generated during the n-th transaction. Since the government spends D dollars, then $a_1$ = D.

Then the second person will receive D dollars and spend $D_c$ dollars. Therefore, $a_2=D_c$ . The next person will receive $D_c$ dollars, which means they are spending $a_3 = (D_c)c = Dc^2$ dollars. Therefore,

$a_1 = D$

$a_2=D_c$

$a_3 = Dc^2$

$a_4 = (Dc^2)c= Dc^3$

....

$a_n=Dc^{n-1}$

∴ $S_n=a_1+a_2+a_3+....+a_n$

$S_n = D+Dc+Dc^2+Dc^3+...+Dc^{n-1}$

$S_n= D(1+c+c^2+...+c^{n-1})$

$S-n=D . \frac{1-c^n}{1-c}$

Suppose Z has a standard normal distribution with a mean of 0 and standard deviation of 1. 27% of the possible Z values are grea

inessss [21]

Answer:

27% of the possible Z values are greater than 0.613

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

$\mu = 0, \sigma = 1$

27% of the possible Z values are greater than

The 100 - 27 = 73rd percentile, which is X when Z has a pvalue of 0.73. So X when the z-score is 0.613.

$Z = \frac{X - \mu}{\sigma}$

$0.613 = \frac{X - 0}{1}$

$X = 0.613$

27% of the possible Z values are greater than 0.613

Y = 8 2 + 3y = Use the substitution method. 9 ਨੇ (4, - 4) 8

Annette [7]

The answer is 26.
This is because, since y is equal to 8, you would put 8 in replacement of y, which is called substituting. It would look something like this.
2 + 3y
2+ 3(8)
2+ 24
26
