Please help ASAP volume of rectangular prism

Answer:

z < -2

g is indeterminate

Step-by-step explanation:

For the inequality Z - ( -7 ) < 5

open the parenthesis

z+7 < 5

Subtract 7 from both sides

z+7-7 < 5-7

z < -2

For 8(3g - 2) <= 12(2g + 1)

Expand

24g -16 ≤ 24g + 12

24g - 24g ≤  12+18

0g≤  28

g ≤  28/0

Hence g is indeterminate

Answer:

5,6

Step-by-step explanation:

Answer:

5 and 6

Step-by-step explanation:

5² = 25

6² = 36

Solution :

According to the question, let

A : winning first scholarship

B : winning second scholarship

So for the first scholarship, there are five finalist and only two scholarship will be awarded. And for the second scholarship there are five finalist and only one scholarship will be awarded.

Therefore,

[tex]$P(A)=\frac{2}{5}$[/tex]   and    [tex]$P(B)=\frac{1}{5}$[/tex]

1. So, [tex]$P(A \cap B ) = P(A) P(B)$[/tex]

                      [tex]$=\frac{2}{5} \times \frac{1}{5}$[/tex]

                      [tex]$=\frac{2}{25}$[/tex]                

2. [tex]$P(A \cup B) = P(A)+P(B)-P(A)P(B)$[/tex]

                   [tex]$=\frac{2}{5}+\frac{1}{5}-\frac{2}{25}$[/tex]

                   [tex]$=\frac{13}{25}$[/tex]

3. She should apply to both the scholarships, so as to have a maximum chances of winning at least one scholarship.

Answer:

1) D: none of them

2) C: ae^(ax)

3) A: cot x

4) A: (3,0)

Step-by-step explanation:

1) the degree of the denominator is more than that of the numerator, thus as n approaches infinity, the function would approach zero. The answer is not available among the options

2) y = e^(ax)

dy/dx = ae^(ax)

3) y = log(sin x)

dy/dx = (1/sin x) × d(sin x)/dx

dy/dx = cosx/sin x

dy/dx = 1/(sin x/cos x)

We know from trigonometry that sin x/cos x = tan x. Thus

dy/dx = 1/tan x

dy/dx = cot x

4) An inflection point is usually the point where the second derivative is equal to zero.

f(x) = x³ - 9x²

f'(x) = 3x² - 18x

f"(x) = 6x - 18

Equating to zero gives;

6x - 18 = 0

x = 18/6

x = 3

Thus the inflection point is (3,0)

Answer:

x = 2

Step-by-step explanation:

1. Add 9 to both sides.

6x=3+9

2. Simplify  3+9  to  12.

6x=12

3. Divide both sides by 6.

x=12/6

4.

Simplify 12/6 to 2

x = 2

Answer:

yes

Step-by-step explanation:

7.8 x c + 3.4 = 19

7.8c + 3.4 = 19

7.8c = 19 - 3.4

7.8c = 15.6 (now divide both sides by 7.8)

x = 2

Answer:

Step-by-step explanation:

From the given information:

(i)

The domain includes all runners in a race.

x is "R" y if x beats y

Now, in a race; either x beats y or y beats x

So, x"R"y or y "R" x, but here at least two runners tied.

Thus, the relation is not in total order as x"R"y or y"R"x may not happen.

(j)

S = {a,b,c,d}

The domain = Power set of S

x"R"y if |X| ≤ |Y|

Thus, the relation is a partial order.

(k)

S = {a,b,c,d}

The domain = Power set of S

x"R"y if |X| ≤ |Y|

Answer:

9/10 divided by 3/4 is 6/5  

3/4 divided by 9 is 1/12

6/9 divided by 6/7 is 7/6

5/6 divided by 3/10 is 25/9 but as a mixed number it is 2 7/9

Answer:

B. 0, 1, 2, 3

Step-by-step explanation:

If n were to be 4, the expression would then be incorrect because 36 is not greater than itself. However, if n was 0, 1, 2, or 3, each value would be less than 36, which is what we are looking for.

36 > 9n

36 > 9(0)

36 > 0

Correct!

36 > 9n

36 > 9(1)

36 > 9

Correct!

36 > 9n

36 > 9(2)

36 > 18

Correct!

36 > 9n

36 > 9(3)

36 > 27

Correct!

36 > 9n

36 > 9(4)

36 > 36

Incorrect! This expression would only be correct if the sign was representative of greater than or equal to, rather than just equal to.

I hope this made sense! Have an amazing day. :)

Answer:

0.0082 = 0.82% probability that a randomly selected person will wait more than 42 seconds.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

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 p-value, we get the probability that the value of the measure is greater than X.

Mean wait time of 30 seconds and a population standard deviation of 5 seconds.

This means that [tex]\mu = 30, \sigma = 5[/tex]

What is the probability that a randomly selected person will wait more than 42 seconds?

This is 1 subtracted by the pvalue of Z when X = 42. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{42 - 30}{5}[/tex]

[tex]Z = 2.4[/tex]

[tex]Z = 2.4[/tex] has a pvalue of 0.9918

1 - 0.9918 = 0.0082

0.0082 = 0.82% probability that a randomly selected person will wait more than 42 seconds.

Step-by-step explanation:

Plug in the value:

1/2 b² – 6

1/2 (4)² – 6

Use order of operations (PEMDAS):

There are no parentheses:

Do exponent:

1/2 (16) – 6

Then multiplication and division in the order that they come in:

8 – 6

Then addition and subtraction in the order that they come in:

Answer:

25%

Step-by-step explanation:

You have a 1/2 chance of getting an even number and a 1/2 chance of getting heads, so you multiply these fractions together and get 1/4, which is equal to 25%

Hope this helps you

Step-by-step explanation:

i)Initial School population,

given 15 units = 1200

1 unit =

[tex]1200 \div 15 \\ = 80[/tex]

Number of teachers (initial) = 1 unit = 80.

ii)take j = number of teachers joining the school.

New teacher population = 80+j

[tex] \frac{3}{43} (1280 + j) = 80 + j \\ \frac{3840}{43} + \frac{3}{43} j = 80 + j \\ j - \frac{3}{43} j = \frac{3840}{43} - 80 \\ \frac{40}{43} j = \frac{400}{43} \\ 40j = 400 \\ j = 400 \div 40 \\ = 10[/tex]
