2 3/8 x 3 3/7 = ?<br><br> Please help me! I hate fractions and don't understand!!!!!!!

(Please Help) Drag a statement or reason to each box to complete this proof.

SOVA2 [1]

Answer:

see the explanation and the attached figure

Step-by-step explanation:

we have

$-2(x+1)=8$ ----> given

Divide by -2 both sides

$-2\frac{(x+1)}{-2} =\frac{8}{-2}$ ----> by Division Property of Equality

Simplifying

$x+1=-4$

Subtract 1 both sides

$x+1-1=-4-1$ ----> by Subtraction Property of Equality

Simplifying

$x=-5$

6.3.6. Among the early attempts to revisit the death postponement theory introduced in Case Study 6.3.2 was an examination of th

kakasveta [241]

Answer:

So the Null hypothesis is rejected in this case

Step-by-step explanation:

The number of celebrities is n = 348

So to solve this we would assume that p is the percentage of people that died on the month preceding their birth month

Generally if there is no death postponement then p will be mathematically evaluated as

$p = \frac{1}{12}$

This implies the probability of date in one month out of the 12 months

Now from the question we can deduce that the hypothesis we are going to be testing is

$Null Hypothesis \ \ H_0 : p = 0.083$

This is a hypothesis is stating that a celebrity dies in the month preceding their birth

$Alternative \ Hypothesis H_1 : p < 0.083$

This is a hypothesis is stating that a celebrity does not die in the month preceding their birth

is c is the represent probability for each celebrity which either c = 0 or c = 1

Where c = 0 is that the probability that the celebrity does not die on the month preceding his/ her birth month

and c = 1 is that the probability that the celebrity dies on the month preceding his/ her birth month

Then it implies that

for

n= 1 + 2 + 3 + .... + 348 celebrities

Then the sum of c for each celebrity would be $c_s = 16$

i.e The number of celebrities that died in the month preceding their birth month

We are told that the significance level is $\alpha = 0.05$ , the the z value of $\alpha$ is

$z_{\alpha } = 1.65$

This is obtained from the z-table

Since this test is carried out on the left side of the area under the normal curve then the critical value will be

$z_{\alpha } = - 1.65$

So what this implies is that $H_o$ will be rejected if

$z \le -1.65$

Here z is the test statistics

Now z is mathematically evaluated as follows

$z = \frac{c - np}{\sqrt{np_o(1- p_o)} }$

$z = \frac{16 - (348 *0.083)}{\sqrt{348*0.083 (1- 0.083)} }$

$z =-2.50$

From our calculation we see that the value of z is less than $-1.65$ so the Null hypothesis will be rejected

Hence this tell us that the evidence provided is not enough to conclude that 16 celebrities died a month to their birth month

If a sponsored link was delivered 100 times and 10 people clicked on it, then the number of impressions is 100, the number of cl

Rudik [331]

Answer:

Option A.

Step-by-step explanation:

It is given that a sponsored link was delivered 100 times and 10 people clicked on it.

Number of impressions = 100

Number of clicks = 10

The formula for click-through-rate (CTR) is

$CTC=\dfrac{\text{Total measured clicks}}{\text{Total measured impression}}\times 100$

$CTC=\dfrac{10}{100}\times 100$

$CTC=10$

The click-through-rate (CTR) would be 10%. Therefore, the correct option is A.
