Answer: B

Step-by-step explanation:

[tex]f(x) = \frac{12}{x} - 18 \\ [/tex]

let its inverse be m :

[tex]m = \frac{12}{x} - 18 \\ \\ m + 18= \frac{12}{x} \\ \\ x = \frac{12}{m + 18} \\ \\ { \boxed{ \boxed{f {}^{ - 1}(x) = \frac{12}{x + 18} }}}[/tex]

Answer:

x = 55

Step-by-step explanation:

To find the value of x

3x - 35 = 130 (vertically opposite angles are equal)

3x = 130 +35

3x = 165

x = 165/3

x = 55

Step-by-step explanation:

Step-by-step explanation:

The amount of money used for scholarship and the fraction of the estate gotten by Miss Maple are :

The entire fraction of the estate = 1/1

Fraction given to children = 2/3

Fraction left = Total - fraction given to children

Fraction left = 1/1 - 2/3 = 1/3

For scholarship :

1/5 of fraction left :

1/5 of 1/3 = 1/5 × 1/3 = 1 /15

Fraction Given to grand children :

1/5 - 1/15 = 2/15

Amount of money used for scholarship :

1/15 × 8424000 = $561,600

B.)

Since There are four grand children and it was equally shared among them:

Miss Maple is one of the grand children:

Fraction each grandchild gets is :

2/15 ÷ 4

2/15 ÷ 4/1

2/15 × 1/4 = 2/60 = 1/30

Hence, miss Maple will get 1/30

Tables are used to show the relationship between variables in a visual form. The equation of the situation is: [tex]y = 7x[/tex]

The complete table is as follows:

[tex]\left[\begin{array}{cccccc}{Pages}&1&2&4&6&8\\{Photos}&7&14&28&42&56\end{array}\right][/tex]

Given that:

[tex]2\ page = 14\ photos[/tex]

Let:

[tex]y \to pages[/tex]

[tex]x \to photos[/tex]

So, we have:

[tex]2y = 14x[/tex]

Divide by 2

[tex]y = 7x[/tex]

To fill the table, we simply multiply both sides by the same constant.

Multiply by 0.5

[tex]2\ page \times 0.5= 14\ photos \times 0.5[/tex]

[tex]1\ page = 7\ photos[/tex]

Multiply by 2

[tex]2\ page \times 2 = 14\ photos \times 2[/tex]

[tex]4\ page = 28\ photos[/tex]

Multiply by 3

[tex]2\ page \times 3 = 14\ photos \times 3[/tex]

[tex]6\ page = 42\ photos[/tex]

So, the table is as follows:

[tex]\left[\begin{array}{cccccc}{Pages}&1&2&4&6&8\\{Photos}&7&14&28&42&56\end{array}\right][/tex]

Answer:

2nd option

Step-by-step explanation:

note that

5n ← generates multiples of 5, that is

5 × 1 = 5

5 × 2 = 10

5 × 3 = 15

5 × 4 = 20 , etc

5, 10, 15, 20, ....... are multiples of 5

but 5n + 1 does not generate multiples of 5 as

5 + 1 = 6

10 + 1 = 11

15 + 1 = 16

20 + 1 = 21

6, 11, 16, 21 are not multiples of 5

Step-by-step explanation:

$15300

$15606

300 is 2% of 15000, so we add that. The result we have is $15300.

306 is 2% of 15300, so we add that to the original value. The result is $15606.

Side note:

All you need to know is the Interest Rate Formula: [tex]p(1+r/100)^n[/tex]. By the way, that's the simple compound interest rate formula. The simple interest rate formula is [tex]p+(r/100)^n[/tex].

Answer:

non mutually exclusive event

Step-by-step explanation:

im not sure on this tho

Answer:

Let them be "x"

5x+3x= $2000

8x= $2000

x= 2000/8

x= 250

5* 250= 1250.

3*250= 750.

The numbers are ordered, such that the first number (the largest one) is:

(5 + 1/2)

And the last number (the smaller one) is (5 + 1/3). Only by knowing this, we will see that the correct options are A and C.

We want to see which of the following numbers is not on the list:

A) √25

B) 5.45

C) 5 12  

D) 5.34

One of these numbers can only be in the list if it is larger than  (5 + 1/3) and smaller than (5 + 1/2).

To see this easier, let´s rewrite both of these:

5 + 1/2 = 5 + 0.5 = 5.5

5 + 1/3 = 5 + 0.33 = 5.33

Then if a number is smaller than 5.33, the number can't be in the list.

Here we can see two numbers that are smaller than 5.33

These are:

Option A) √25 = 5 < 5.33

Option C) 5.12 < 5.33

And there is no number larger than 5.5

Concluding, the numbers that are not in Demichael's list are:

√25 and 5.12

Answer:

44

Step-by-step explanation:

Let S = strawberry count

Chocolate = 1/4 * 80 = 20

Vanilla = 1/5 * 80 = 16

Total = C + V + S

80 = 20 + 16 + S

80 - 20 - 16 = S = 44

Answer:  Choice C.

The difference between our sample mean and our hypothesized mean was statistically significant.

=========================================================

Explanation:

The null hypothesis is always set up in a way to state the following: "The mean mu is equal to some value"

The mu is a greek letter often used as the population mean symbol. The actual symbol itself looks like this [tex]\mu[/tex]

When we reject the null, we reject the idea that the mu is whatever stated value we said in the null. So we must go with the alternative hypothesis.

The sample mean we computed (xbar) is different enough from the mu value that we're able to make such a rejection. We consider this statistically significant, which is another way of saying that such a difference is not simply due to random chance.
