Answer:

y=6

Step-by-step explanation:

y= -3/2(-4) : y=4

y=-2 3/4(-4)

y=3/2. 4

y= 3×4/2

y =12/2

12/2 =6

y =6

Answer:

315,360 I had to assume you needed that number, 292000+8%=315360

Answer:

x = 40 or x = 4(10)

Step-by-step explanation:

If x is the total number of apples in the basket then the equation would be

x = 40 or x = 4(10). (Double check to make sure I'm correct)

Answer:

the answer should be 27.72

Answer:

4 pounds and 2/3 of a pound

each bag would contain 2 pounds and 1/3 of a pound so two pounds would be two times that so 4 pounds and 2/3 of a pound is the answer.

i.dk if this is what u needed but good luck

hope this helped

Answer:

121π square centimeters

Step-by-step explanation:

We can find the radius of the circle by taking the average of the two diameters provided. (15+7)/2=11. Then we plug that into the area of a circle equation. Area = π[tex]r^{2}[/tex] and that yields the answer.

Answer:

1/ 1000 ;

X : _____ 0 ___________ 390

P(x) : ___ 999/1000 ___ 1/ 1000 ;

0.39 ;

D ;

-$61

Step-by-step explanation:

1.)

Probability of winning with a single bet:

Winning numbers in lottery = 1

Lottery size = 1000

P(winning per bet) = 1/ 1000

2.)

X : _____ 0 ___________ 390

P(x) : ___ 999/1000 ___ 1/ 1000

3.)

Σx*p(x)

(0 * 999/1000) + (390 * 1/1000)

0 + 390 / 1000

= 0.39

4)

Expected winning :

Loss = - 1 * 999/1000 ; win = 390 * 1/1000

- 0.999 + 0.39 = - 0.609 = - $0.61

Hence, on average, for every $1 bet, I lose $0.61 on average

E.)

Expected winning for playing 100 times ;

Loss per play:

Expected winning * 100

-$0.61 * 100 = -$61

Loss of - $61 on average

Answer:

Yes, they are similar.

[tex]AB\approx 127.3947[/tex]

Step-by-step explanation:

Part 1)

Yes.

First, ∠D and ∠B are both right angles, so they are congruent.

Next, ∠DCE and ∠BCA are vertical angles. So, their measures are congruent.

Then by Angle-Angle Similarity, we acquire:

[tex]\Delta EDC\sim \Delta ABC[/tex]

Part 2)

The corresponding sides of similar triangles are proportional.

Therefore:

[tex]\displaystyle \frac{DE}{DC}=\frac{AB}{BC}[/tex]

By substitution:

[tex]\displaystyle \frac{103}{76}=\frac{AB}{94}[/tex]

Cross-multiply:

[tex]76AB=9682[/tex]

So:

[tex]AB=9682/76\approx127.3947[/tex]

Answer:

18,000

Step-by-step explanation:

6% is 0.06

300,000 * 0.06 = 18,000

Answer:

John's commision is $18,000

Step-by-step explanation:

This is is essentially asking what 6% of $300,000 is.

6% in decimal form equals 0.06

You then multiple the decimal to the orginal value.

(0.06)(300,000) = 18,000

John's commision is $18,000

Answer:

[tex]Unit = 2\frac{2}{3}[/tex]

Step-by-step explanation:

Given

[tex]Bags = 8[/tex]

[tex]Bowls = 3[/tex]

Required

Determine the amount in each bowl

This implies that we calculate the unit measurement. This is calculated using:

[tex]Unit = \frac{Bags}{Bowls}[/tex]

[tex]Unit = \frac{8}{3}[/tex]

[tex]Unit = 2\frac{2}{3}[/tex]

Answer:

Area=1/2bh

Given area of 36m^2

1/2(x)(x-1)=36

Multiply both sides by 2 to remove deminator

(x)(x-1)=72

X^2-x=72

X^2-x-72=0 then factor

(x-9)(x+8)=0

X=9,-8 however since area must be positive, take the absolute value of 8

1/2(9m*8m)=36m^2

Answer:

Step-by-step explanation:

It's because the only whole number factor pair to 10 is 2x5 and luckily, it turned out that 5-3=2, so there are no decimals or fractions.

Answer: I think the red moon is equal to 64 because 64 is half of 128, and I think the purple square is equal to 12 because if you add all of the other shapes, they equal 52 and 64 - 52 is 12.

Answer:

0.5819 = 58.19% probability that five or more families have life insurance

Step-by-step explanation:

For each family, there are only two possible outcomes. Either they have insurance, or they do not. The probability of a family having insurance is independent of other families. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

77% of husband-wife families with kids under 18 years old have life insurance.

This means that [tex]p = 0.77[/tex]

A random sample of six husband-wife families was selected.

This means that [tex]n = 6[/tex]

What is the probability that five or more families have life insurance?

This is

[tex]P(X \geq 5) = P(X = 5) + P(X = 6)[/tex]

In which

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 5) = C_{6,5}.(0.77)^{5}.(0.23)^{1} = 0.3735[/tex]

[tex]P(X = 6) = C_{6,6}.(0.77)^{6}.(0.23)^{0} = 0.2084[/tex]

[tex]P(X \geq 5) = P(X = 5) + P(X = 6) = 0.3735 + 0.2084 = 0.5819[/tex]

0.5819 = 58.19% probability that five or more families have life insurance

Answer:

24 glasses

Step-by-step explanation:

We are given that

Estelle has juice=6 liters

She pours juice in one glass=0.25 L

We have to find the number of glasses of juice made by her.

Using unitary method

0.25 L juice pour in 1 glass

1 L juice pour in 1/0.25 glasses

6 liters  juice pour in glasses=[tex]\frac{1}{0.25}\times 6[/tex]

6 liters  juice pour in 24 glasses

Hence, she will make 24 glasses of juice.

Answer:

4 feet

Step-by-step explanation:

Let x be the height of the tower when finished.

We have been given that Priya takes a break when the tower is 2 and 1/2 feet tall, which is 5/8 of the height of the tower she wants to build.

This means that 5/8 of x equals 2 and 1/2. Let us represent this information in an equation.

5/8*x=2 and 1/2

Let us convert our given mixed fraction into an improper fraction.

5/8*x=5/2

Let us multiply both sides of our equation by 8/5.

8/5*5/8*x=5/2*8/5

x=8/2

x=4
