Answer:
49 ÷ 7 = 7
Step-by-step explanation:
We assume your intended quotients are ...
49 ÷ 7 = 7
4.9 ÷ 7 = 0.7
0.49 ÷ 0.7 = 0.7
0.049 ÷ 0.07 = 0.7
The one that is different is 49 ÷ 7.
__
Evaluation of the quotients tells you which is different. Inspection of place values also tells you which is different. In all but the first quotient, the 4 and the 7 are in the same number place, so the quotients will be the same value.

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:
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.

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
A basket is filled with apples. There are 10 green apples, which is 25% of the total number of apples in the basket. Which equation can be used to determine x, the total number of apples in the basket
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)

~[tex]\frak{Amphitrite1040:)}[/tex]Find the height of the triangle if the area is 36 m 2
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
Estelle has 6 liters of juice. If she pours 0.25 liters into each glass, how many glasses of juice will she make?
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.
According to LIMRA, 77% of husband-wife families with kids under 18 years old have life insurance. A random sample of six husband-wife families was selected. What is the probability that five or more families have life insurance?
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

What is the result when the number 44 is increased by 25%?
Answer:
55
Step-by-step explanation:
25% = 1/4
1/4 of 44 is 11
44+11= 55.
Answer: 44 increased by 25% = 55
Step-by-step explanation:
25% x 44 = 11
44 + 11 = 55

John makes a commission of 6% when he sells a house how much is john's commission if he is sells a house for $300,000
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

for the salad bar Jenning must divide 8 bags of lettuce equally among 3 serving bowls how many bags of lettuce would be in each serving Bowl if they were divided equally?
A. 3/8
B. 3/7
C. 2 1/3
D. 2 2/3
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]
(1+2) +3 = 1 + (2 + 3)

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]
The state of Georgia has several statewide lottery options. One of the simpler ones is a "Pick 3" game in which you pick one of the 1000 three-digit numbers between 000 and 999. The lottery selects a three-digit number at random. With a bet of $1, you win $390 if your number is selected and nothing ($0) otherwise.
(a) With a single $1 bet, what is the probability that you win $390?
(b) Let x denote your winnings for a $1 bet, so x = $0 or x = $390. Construct the probability distribution for X. Use 3 decimal places.
(c) The mean of the distribution equals ___________ X cents for the dollar paid to play.
(d) Would this be considered a gain for you?
No. For every $1 I pay, I will lose $0.39 on average.
No. For every $1 I pay, I will lose $ 0.61 on average.
Yes. For every $1 I pay, I will win $0.39 on average.
(e) If you play "PICK 3" 100 times, how much should you expect to lose?
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
