Answer:
8
Step-by-step explanation:
You add 4 to get the next number.
(-8) + 4 = (-4)
(-4) + 4 = 0
0 + 4 = 4
4 + 4 = 8
The quotient of two times a number and 5 is no more than 14.

Step-by-step explanation:
5 members or 20% of the math league did not come to the meet. how many total members are there
5 = (20%) x (total)
5 = (0.20) x (total)
Divide each side by (0.20):
Total = (5 / 0.20)
Total = 25

( -8)(2)
= 16
Step-by-step explanation:
where there's x put-3 and where there's y put-5
I don't see =0 so I don't believe you will have to equate further
Answer:
-16
Step-by-step explanation:
Hello There!
For this one we also need to plug in the values and solve
(-3+(-5)(-3-(-5)
first lets distribute the -3 to -3 and -(-5)
-3x-3=9
-3x5=-15
9-15=-6
now lets distribute the -5 to the -3 and -(-5)
-5x-3=15
-5x5=-25
-25+15=-10
-10-6=-16
so the answer would be -16
25 liters of water are pumped into a dam in 20 seconds
how much water will be pumped in within 3 minutes??? help please
1 minute = 60 seconds.
3 minutes x 60 seconds = 180 seconds.
180 seconds / 20 = 9
25 liters x 9 = 225
Total water in 3 minutes = 225 liters
Answer:
225 liters
Step-by-step explanation:
There is 25 liters in 20 seconds, so you keep adding 20 seconds while adding 25 liters each time. 180 = 3 minutes
25 20
50 40
75 60
100 80
125 100
150 120

There are 6 red marbles, 8 blue marbles, and 11 green marbles in a bag. What is the probability that you will randomly draw either a red or a blue marble?
A) 24%
B) 32%
C) 56%
D) 10%
Answer:Total marbles = 6 + 8 + 11 = 25
Total red or blue marbles = 6 + 8 = 14
P(either a red or blue) = 14/25
Change it to percentage = 14/25 x 100 = 56%

Answer:
9 inches
Step-by-step explanation:
Let's call the width x and length 2x
The perimeter is calculated by adding all side lengths
so x + 2x + x + 2x = 54 inches add like terms
6x = 54 divide both sides by 6
x = 9 inches that's the answer.

Answer:
15.9
Step-by-step explanation:
Formula:
a² + b² = c²
6² + x² = 17²
36 + x² = 289
x² = 253
[tex]\sqrt{x^2} =\sqrt{253}[/tex]
x = 15.91
The value of x will be equal to x = 15.9.
The Pythagorean theorem says that the sum of the square of the perpendicular and the base will be equal to the square of the hypotenuse of the right-angle triangle.
Given that the sides of the triangle are,
a = 6,
b = x
c = 17
The value of x will be calculated as,
a² + b² = c²
6² + x² = 17²
36 + x² = 289
x² = 253
x = 15.91
Therefore, the value of x will be equal to 15.91.

Without doing calculations choose the equation that you can NOT use to answer the question. What number is 55% of 80?
Answer: See explanation
Step-by-step explanation:
You didn't specify the equations but let me solve the question.
55% of 80.
The above statement simply means that you need to multiply 55% by 80. This will be:
= 55% of 80
= 55/100 × 80
= 0.55 × 80
= 44
Therefore, 55% of 80 is 44
Based on your question, any other equation that doesn't give 44 as an answer cannot be used to answer the question.

A rectangular yard is X feet wide. The yard is 4 feet longer than it is wide. The perimeter P of yard is given by the equation P= 4x + 8. If the perimeter of the yard is 84 feet how long is the yard?
A. 19 feet
B. 23 feet
C. 24 feet
D. 28 feet
Given:
Width of the rectangular yard = x feet
Length of the rectangular yard = x+4 feet
Perimeter of the rectangular yard is:
[tex]P=4x+8[/tex]
Perimeter of the yard = 84 feet
To find:
The length of the rectangular yard.
Solution:
Perimeter of the yard is 84 feet.
[tex]4x+8=84[/tex]
[tex]4x=84-8[/tex]
[tex]4x=76[/tex]
Divide both sides by 4.
[tex]x=\dfrac{76}{4}[/tex]
[tex]x=19[/tex]
So, the width of the rectangular yard is 19 feet.
Length = [tex]19+4[/tex]
Length = [tex]23[/tex]
The length of the rectangular field is 23 feet.
Therefore, the correct option is B.

Eight percent of all college graduates hired by companies stay with the same company for more than five years. The probability, rounded to four decimal places, that in a random sample of 11 such college graduates hired recently by companies, exactly 2 will stay with the same company for more than five years is: the absolute tolerance is /-0.0001
Answer:
0.1662 = 16.62% probability that exactly 2 will stay with the same company for more than five years
Step-by-step explanation:
For each graduate, there are only two possible outcomes. Either they stay for the same company for more than five years, or they do not. Graduates are independent. This means that 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.
Eight percent of all college graduates hired by companies stay with the same company for more than five years.
This means that [tex]p = 0.08[/tex]
Sample of 11 college graduates:
This means that [tex]n = 11[/tex]
The probability, rounded to four decimal places, that in a random sample of 11 such college graduates hired recently by companies, exactly 2 will stay with the same company for more than five years is: the absolute tolerance is +-0.0001
The tolerance means that the answer is rounded to four decimal places.
The probability is P(X = 2). So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 2) = C_{11,2}.(0.08)^{2}.(0.92)^{11} = 0.1662[/tex]
0.1662 = 16.62% probability that exactly 2 will stay with the same company for more than five years
I need help with Mean, Median and Mode
Answer:
there is no attachments but The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set. The median is the middle value when a data set is ordered from least to greatest. The mode is the number that occurs most often in a data set.

Answer:
F = (-2,4); E = (-2,0); D = (2,0)
Step-by-step explanation:
F = 4 points from A, so by a scale factor of 2, it would be 2 times father away from A. The same thing applies for all of the other points; just find how much father A is from a point, then dilate that point by multiplying it by the scale factor, and settling the point closer or father from A.
