Answer:

3. 9 (6/12)

4. 4 (3/12)

Step-by-step explanation:

Question 3:

6 (2/6) × 1 (1/2)

multiply the whole number by the denominator

6 x 6 = 36 + 2 (numerator) = 38/6

2 x 1 = 2 + 1 = 3/2

(38/6) x (3/2)

multiply (3/2) by 3

3 x 3 = 9

2 x 3 = 6

38/6 x 9/6

38 x 9 = 342

6 x 6 = 36

19/2 = 9 (1/2) or 9 (6/12)

Question 4:

5 (2/3) × (3/4)

15 + 2 = 17

17/3 x 3/4

17 x 4 = 68

3 x 4 = 12

3 x 3 = 9

4 x 3 = 12

(68/12) x (9/12)

68 x 9 = 612

12 x 12 = 144

612/144 = 4 (1/4) or 4 (3/12)

I hope this helps! I'm sorry if this is confusing.

In a Caesar Cipher system, if encryption is done by the rule c = E(p+k) = p + 9, then the letter ‘q’ is encrypted as what other

Vaselesa [24]

Answer:

Step-by-step explanation:

There has to be a mod 26 operation for c, since the alphabet only has 26 letters.

But otherwise

$c = E(p+k) = p + 9 \mod{26}$

p is the initial position of the letter. So for example, a = 0, b = 1, c = 2, q = 16, z = 25...

9 is by how much the encrypted character will change relative to the original.

We want to cipher the letter q.

So p = 25.

$c = E(p+k) = p + 9 \mod{26}$

$c = 25 + 9 \mod{26}$

$c = 34 \mod{26}$

The remainder of 34 divided by 26 is 8.

$c = 8$

Which means that q is encrypted as 'i'.

An advertisement for a popular weight-loss clinic suggests that participants in its new diet program lose, on average, more than

Sedbober [7]

Testing the hypothesis, it is found that:

The null hypothesis is: $H_0: \mu \leq 10$

The alternative hypothesis is: $H_1: \mu > 10$

The critical value is: $t_c = 1.74$

The decision rule is:

If t < 1.74, we do not reject the null hypothesis.
If t > 1.74, we reject the null hypothesis.

Since t = 1.41 < 1.74, we do not reject the null hypothesis, that is, it cannot be concluded that the mean weight loss is of more than 10 pounds.

Item a:

At the null hypothesis, it is tested if the mean loss is of at most 10 pounds, that is:

$H_0: \mu \leq 10$

At the alternative hypothesis, it is tested if the mean loss is of more than 10 pounds, that is:

$H_1: \mu > 10$

Item b:

We are having a right-tailed test, as we are testing if the mean is more than a value, with a significance level of 0.05 and 18 - 1 = 17 df.

Hence, using a calculator for the t-distribution, the critical value is: $t_c = 1.74$ .

Hence, the decision rule is:

If t < 1.74, we do not reject the null hypothesis.
If t > 1.74, we reject the null hypothesis.

Item c:

We have the standard deviation for the sample, hence the t-distribution is used. The test statistic is given by:

$t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}$

The parameters are:

$\overline{x}$ is the sample mean.
$\mu$ is the value tested at the null hypothesis.
s is the standard deviation of the sample.
n is the sample size.

For this problem, we have that:

$\overline{x} = 10.8, \mu = 10, s = 2.4, n = 18$

Thus, the value of the test statistic is:

$t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}$

$t = \frac{10.8 - 10}{\frac{2.4}{\sqrt{18}}}$

$t = 1.41$

Since t = 1.41 < 1.74, we do not reject the null hypothesis, that is, it cannot be concluded that the mean weight loss is of more than 10 pounds.

WILL GIVE BRAINLIEST IF RIGHT how do you find the growth factor of a graph

notsponge [240]

Answer:

The growth "rate" (r) is determined as b = 1 + r.

Step-by-step explanation:

A growth factor is the factor by which a quantity multiplies itself over time. When trying to find the growth rate, you have to remember that the original exponential formula was y = ab^x. You will notice that in these new growth and decay functions, the b value (growth factor) has been replaced either by (1 + r) or by (1 - r). The growth "rate" (r) is determined as b = 1 + r.

Which shows the expression below in simplified form? (2.4 × 1018) + (3.4 × 1015)

RUDIKE [14]

Answer: 5894.2

Step-by-step explanation:

You'll want to follow PEMDAS to simplify this expression.

1.) P - Parentheses

2.) E - Exponents

3.) M - Multiplication

4.) D - Division

5.) A - Addition

6.) S - Subtraction

We'll start with what's inside the parentheses:

(2.4 × 1018) + (3.4 × 1015)

(2,443.2) + (3,451)

Now all you have to do is add the values together to get your answer!

2,443.2 + 3,451

5894.2
