Answer:

67

Step-by-step explanation:

I THINK THIS IS THE ANSWER

I've attached an image showing the data relationship.

Answer:

1) y does not change based on changes in x: no-correlation

2) y tends to increase as x increases: positive correlation

3) y tends to decrease as x increases: negative correlation

Step-by-step explanation:

1) y does not change based on changes in x: This means that there is no correlation between y and x since change in x doesn't affect y.

2) y tends to increase as x increases: This implies positive correlation because the output increases with increase in input.

3) y tends to decrease as x increases: This implies negative correlation because the output decreases with increase in input values.

Answer:

y tends to decrease as x increases: negative!

y tends to increase as x decreases: positive!

y does not change based on changes in x: no correlation!

I just checked with a calculator, and the mean stays the same.

So the answer is the first option! :D

Answer:

x=1

Step-by-step explanation:

Distribute 5/8 to x and -1/3 which will result you in 5/8x - 5/24

The equation now looks like this:

5/8x - 5/24= 5/12

Move -5/24 to the other side by adding 5/24 on both sides

5/8x - 5/24 + 5/24 = 5/12+5/24

(Multiply 2 and 5/12 on both the numerator and denominator which will result you to 10/12 add 5/24 which is 15/24)

Result:

5/8x=15/24

Multiply by 8/5 on both sides:

x=1

Answer:

No, P(A) ≠ P(A|B)

Step-by-step explanation:

Condition must be held in order to two events be independent of each other:

[tex]P(A B) = P(A)P(B) => P(A) = P(A|B)\\Or\\P(B) = P(B|A)[/tex]

[tex]P(A)=\frac{42}{81}\\P(B) =\frac{46}{81}\\P(A B) = \frac{20}{81}\\P(A|B) =\frac{P(A B)}{P(B)} = \frac{20}{46} \neq P(A) => P(AB) = \frac{20}{81} \neq P(A)P(B) = \frac{23}{81}\\\\P(B|A)=\frac{P(AB)}{P(A)}=\frac{20}{42} \neq P(B) => P(AB) = \frac{20}{81} \neq P(A)P(B)= \frac{23}{81}\\\\[/tex]

Note: (AB) means (A ∩ B)

The probability of P(A) is not equal to the probability of P(A|B) option third No, P(A) ≠ P(A|B) is correct.

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.

Two events must be independent of each other, condition must be maintained:

P(A and B) = P(A) × P(B)

The probability:

P(A) = 42/81

P(B) = 46/81

P(AB) = 20/81

P(A|B) = P(AB)/P(B) = 20/46 ≠ P(A) = 20/81 ≠ P(A)P(B) = 23/81

P(B|A) = P(AB)/P(A) = 20/42 ≠ P(B) = 20/81 ≠ P(A)P(B) = 23/81

Thus, the probability of P(A) is not equal to the probability of P(A|B) option third No, P(A) ≠ P(A|B) is correct.

Answer:

xy=5

Step-by-step explanation:

from the question, y varies directly with x and y

Then y ∝ xy

If we introduce proportionality sign we have

y=r xy

Where r= proportionality constant

Then if we substitute the given values

y = 25 when r = 5.

We have

y=r xy

25=5xy

Divide both sides by 5

xy=25/5

xy=5

Hence, equation that models the statement is xy=5

Answer x=22/5 or 4.4

Step-by-step explanation:

1. Combine like terms

15x-12=54

2. Add 12 to both sides

15x=66

3. Divide both sides by 15

15x/15=66/15

4. x=22/5 or 4.4

9514 1404 393

Answer:

  x = 4.4

Step-by-step explanation:

This equation has x-terms on one side of the equal sign and constants on both sides.

First, collect terms.

  15x -12 = 54

Then add the opposite of the constant that is on the same side as the x-term.

  15x = 66

Now, divide by the coefficient of x.

  x = 66/15 = 22/5

  x = 4.4

Answer:

f=4

Step-by-step explanation:

-11f = 7(1-2f)+5

step 1 distribute what is outside of the parenthesis to the inside of the parenthesis

-11f=7-14f+5

step 2 combine like terms

-11f=12-14f

step 3 add 14 to each side

3f=12

step 4 divide each side by 3

f=4

Answer:

YD=6.9

Step-by-step explanation:

In an isosceles trapezoid both diagonals have an equal length. Given this, since diagonal AC is equal to 17.2, diagonal BD must be equal to 17.2. Diagonal BD is made up of segments BY and YD, so the lengths of BY and YD must add to equal 17.2. Since BY is 10.3, the equation YD+10.3=17.2 can be used to find the value of YD. To solve this, subtract 10.3 from both sides of the equation to find that YD is equal to 6.9.

Answer:

Step-by-step explanation:

x + 0.7 = 1 - 0.2x

Add 0.2x to both sides

x + 0.2x + 0.7 = 1 - 0.2x + 0.2x

1.2x + 0.7 = 1

Subtract 0.7 from both sides:

1.2x + 0.7 - 0.7 = 1 - 0.7

1.2x = 0.3

Divide both sides by 1.2:

1.2x/1.2 = 0.3/1.2

x = 0.25

Answer:

X=0.25

Step-by-step explanation: x + 0.7 = 1 - 0.2x

Add 0.2x to both sides

x + 0.2x + 0.7 = 1 - 0.2x + 0.2x

1.2x + 0.7 = 1

Subtract 0.7 from both sides:

1.2x + 0.7 - 0.7 = 1 - 0.7

1.2x = 0.3

Divide both sides by 1.2:

1.2x/1.2 = 0.3/1.2

x = 0.25

Step-by-step explanation:

The ratio of bananas to strawberries is 3:4.

That means for every 3 bananas you buy, you buy 4 strawberries.

That also means that for every 4 strawberries you buy, you buy 3 bananas.

The number of bananas you buy is 3/4 of the number of strawberries you buy.

If you buy n strawberries, then the number of bananas you buy is

Answer:

it is and y=4x

(i'm pretty tired so I can't include an explanation.)

Answer:

Yes it's a proportional relationship

Step-by-step explanation:

0x4=0

2x4=8

4x4=16

6x4=24

8x4=32

Step-by-step explanation:

Amount borrowed=400

interest rate=4%

Amount of interest after x years =0.04XxX400=$16x

Total to be paid back=400+0.04XxX400=400+16(1)

1) the amount of interest.if Franco pays back the loan in x=1 years is

16x1=$16

2) the amount of interest,if Franco pay back the loan in x=2 years is,

16x2=$32

3) the amount of franco will pay the lender after 2 years will be

400+(16x2)=400+32=$432

Answer:

[tex]2 \sqrt{ - 2 } [/tex]
