Answer:
22.5%
Step-by-step explanation:
Find new values:
124(1−0.25)=93
125(1−0.2)=100
Last Year: Boys 124 & Girls 125
This Year: Boys 93 & Girls 100
Total: Last Year 249 & This Year 193
249(1−r)=193
249(1−r)/249=193/249
1−r=0.7751
−r=−0.2249(Subtracted 1)
r=0.2249(Divided by -1)
Final Answer: 22.5%(Multiply by 100 and round to nearest 10th)

A test question asks you to find two side lengths of a 45° -45° -90° triangle. You know that the length of one leg is 6, but you forgot the special formula for 45° -45° -90° triangles. Explain how you can still determine the other side lengths. What are the other side lengths?
Answer:
The other leg is 6 and the Hypotenuse is 6√2
Step-by-step explanation:
because it's a 45 45 90 the legs equal and the Hypotenuse is square root 2 times leg

A manufacturing corporation make tires with a probability 0.79 of lasting over 3,000 miles. What is the probability of exactly seven out of the next eight tires lasting over 3,000 miles?
(Round your answer to three decimal places.)
Answer:
A manufacturing corporation make tires with a probability 0.77 of lasting over 3,000 miles.
Step-by-step explanation:
The probability of exactly seven out of the next eight tires lasting over 3,000 miles will be 0.32.
How to find that a given condition can be modelled by binomial distribution?Binomial distributions consist of n independent Bernoulli trials.
Bernoulli's trials are those trials which end up randomly either on success (with probability p) or on failures (with probability 1- p = q (say))
The probability that out of n trials, there'd be x successes is given by
[tex]\rm P(X =x) = \: ^nC_x \ p^x(1-p)^{n-x}[/tex]
A manufacturing corporation make tires with a probability 0.79 of lasting over 3,000 miles.
The probability of exactly seven out of the next eight tires lasting over 3,000 miles will be
P(x = 7) = ⁸C₇ (0.79)⁷ (1 – 0.79)⁽⁸⁻⁷⁾
P(x = 7) = 0.32

An 8-year-old boy is half his sister's age. When the boy is 12, how old will his sister be?
Answer:
20 years
Step-by-step explanation:
when the boy is 8 and half his sisters age his sister is 16
four years later the boy will be twelve, so if his sister was 16 four years later she will be 20
Answer:
20 years old
Step-by-step explanation:
Let n represent the age of the boy's sister then...
[tex]8=\frac{1}{2}n[/tex]
Multiply both sides by 2
[tex]n=16[/tex]
When the boy is 12, it will be 4 years from when he is 8 therefore...
16 + 4 = 20 years old

Step-by-step explanation:
in order for students to have a club at school they need a minimum of 26 students. If there are 19
students signed up for the club, how many more students does the club need?
What are the solutions? Select the correct choice below and fill in the answer box to complete your
choice
Answer:
7 more students.Basic subtraction:
needed students: minimum required students - students signed up
needed students: 26 - 19
needed students: 7 students, the club needs.
Solution:
We know that the inequality form is x ≥ 26. If we subtract the number of students required by the number of students joined, we will obtain the required students to start the club.
=> Required students - Students joined = Students remained to join=> 26 - 19 = Students remained to join=> 7 studentsHence, the club needs 7 more students to have a club.
A deck is shaped like a parallelogram with a base length of 27 feet and a height of 11 feet. A can of wood stain will cover 40 square feet.
How many cans of stain will be needed to stain the deck?
Enter your answer in the box.
From the area of the parallelogram, it is found that 8 cans of stain will be needed to stain the deck.
What is the area of a parallelogram?The area of a parallelogram of base length l and height h is given by:
A = lh
In this problem, the dimensions are l = 27, h = 11.
Hence, the area, in square feet, is given by:
A = 27(11) = 297.
Each can cover 40 square feet. How many cans are needed for 297 square feet?
[tex]n = \frac{297}{40} = 7.425[/tex]
Rounding up, 8 cans of stain will be needed to stain the deck.

Answer:
130 degrees
Step-by-step explanation:
The right top triangle is isosceles, so the supplementary angle of angle α is (180 - 80)/2 = 50 degrees.
Therefore, α = 180 - 50 = 130 degrees.

Three workers are digging a ditch. They take turns working, and every one of them works for as long as it would take the other two to dig half of the ditch. They finished digging the ditch working in this manner. How many times faster would the three workers have finished digging the ditch if they had all been working at the same time?
The work would be finished 2.25 times faster if they had been doing the work at the same time.
Rate of doing workAssumption;
Provided each one of the workers works for an hour which is equivalent to the time it takes to finish half of the ditch.In essence, the total time required to finish the ditch by 2 workers is; 2 hours.
Hence, for 3 workers working simultaneously, the time required is 1hour 20 minutes. = 80 minutesHowever, since they took 1 hour turns on the job, it follows that; The total time used is;
Total time = 3 × 1hr = 3 hours = 180 hoursHence they could have finished the work in;

tori has to place one more x on the line plot for the eighth month then the total length in hours of all the calls for the eighth month will be 6 hours what is the length in hours of tori's phone calls for just eight months.
Talks 1hr month 9
Talks 1 1/2 hrs 10 and. 11th month
Ta;ks. 3/4 hr 12th month
Line plots are used to express variables using markers
The total phone call for eight months is [tex]10\frac 34[/tex] hours
How to determine the total phone callsFrom the line plot, we have the following summation
[tex]Total = 1hr + 1\frac 12 hr * 2 + \frac 34 hr[/tex]
When the total hours of phone call for the 8th month is added, the summation equation becomes
[tex]Total = 1hr + 1\frac 12 hr * 2+ \frac 34 hr + 6 hr[/tex]
Add the expressions
[tex]Total = 10\frac 34[/tex]
Hence, the total phone call for eight months is [tex]10\frac 34[/tex] hours
