a gym class has 10 boys and 12 girls. how many ways can a team of 6 be selected if the team must have the same number of boys and girls
Answer:
The number of ways of selecting the team is 26,400 ways.
Step-by-step explanation:
Given;
total number boys in the gym, b = 10 boys
total number of girls in the gym, g = 12 girls
number of team to be selected, n = 6
If there must equal number of boys and girls in the team, then the team must consist of 3 boys and 3 girls.
Number of ways of choosing 3 boys from the total of 10 = [tex]10_C_3[/tex]
Number of ways of choosing 3 girls from a total of 12 = [tex]12_C_3[/tex]
The number of ways of combining the two possibilities;
[tex]n = 10_C_3 \times 12_C_3\\\\n = \frac{10!}{7!3!} \ \times \ \frac{12!}{9!3!} \\\\n = \frac{10\times 9 \times 8}{3\times 2} \ \times \ \frac{12\times 11 \times 10}{3\times 2} \\\\n = 120 \times 220\\\\n = 26,400 \ ways[/tex]
Therefore, the number of ways of selecting the team is 26,400 ways.

An arc of 10 meters is formed by a central angle A on a circle radius 4. The measure of A In degrees (to two decimal places) is___.
A. 143.24
B. 36.76
C. 2.50
D. 216.76
Answer:
arc length = circumference • [central angle (degrees) ÷ 360]
central angle (degrees) = 360 * arc length / circumference
circumference = PI * 2 * 4 = 25.1327412287
central angle (degrees) = 360 * 10 / 25.1327412287
central angle (degrees) = 143.2394487828

Find the volume of a cone whose height is 12 and whose radius is 4. Use 3.14 for Pi and round your final answer to one decimal place.
Answer:
201.088 cubic units
Step-by-step explanation:
Given data
height= 12 units
radius= 4 units
The expression for the volume of a cone is given as
Volume = 1/3*πr^2h
Substitute the given data to find the volume of the cone
Volunme= 1/3* 3.142* 4^2* 12
Volume = 1/3* 3.142* 16*12
Volume= 1/3* 603.264
Volume= 201.088 cubic units

The standard normal curve shown below is a probability density curve for a continuous random variable. This means that the area underneath the entire curve is 1. What is the area of the shaded region between the two z-scores indicated in the diagram?
A. 0.6375
B. 0.4263
C. 0.6825
D. 0.6872
E, 0.8937
Answer:
D
Step-by-step explanation:
use the formula for this
The area of the shaded region between the two z-scores is 0.4263.
The z-scores in the diagram are -1.0 and 1.0. The z-score of -1.0 represents a point that is 1 standard deviation below the mean, and the z-score of 1.0 represents a point that is 1 standard deviation above the mean.
The shaded region represents the area under the standard normal curve between the two z-scores. This area is equal to the probability that a standard normal variable will take on a value between -1.0 and 1.0.
To find the area of the shaded region, we can use a z-table. A z-table is a table that shows the area under the standard normal curve for different z-scores.
Looking up the z-scores of -1.0 and 1.0 in the z-table, we find that the area between the two z-scores is 0.4263.

There are four people in Haydens family. Each person always eats 3/4 of a cheese pizza. How many whole pizzas should they order?
Solve and Draw a picture to solve the problem.
Write and equation that matches this problem
The equation that matches the problem is: Total pizzas = 4 × (3/4). Hayden's family should order 3 whole pizzas.
To solve this problem, we need to find the total number of pizzas needed for Hayden's family. Since each person eats 3/4 of a pizza, we can multiply this fraction by the number of people in the family:
Total pizzas = 4 × (3/4) = 12/4 = 3
Therefore, Hayden's family should order 3 whole pizzas.
As for the picture, imagine a circle representing a whole pizza. Divide it into four equal parts to represent each person's portion (3/4). Repeat this division three times to represent the three pizzas needed.

Answer:
y = 2x.
Step-by-step explanation:
The slope = (6 - (-4))/(3 - (-2))
= (6 + 4)/(3+2)
= 10/5
= 2.
Using this and the point (3, 6) we have:
y - 6 = 2(x - 3)
y = 2x - 6 + 6
y = 2x.

A man owns 3/4 of the share of a business and sells 1/3 of his
shares for Birr 10,000. What is the value of the business in Bir?
Given:
A man owns 3/4 of the share of a business and sells 1/3 of his shares for Bir 10,000.
To find:
The value of the business in Bir.
Solution:
Let x be the value of the business.
It is given that a man owns 3/4 of the share of a business and sells 1/3 of his shares for Bir 10,000.
[tex]x\times \dfrac{3}{4}\times \dfrac{1}{3}=10000[/tex]
[tex]x\times \dfrac{1}{4}=10000[/tex]
Multiply both sides by 4.
[tex]x=4\times 10000[/tex]
[tex]x=40000[/tex]
Therefore, the value of the business is 40,000 Bir.

?
In an arithmetic sequence, every pair of consecutive terms differs by a fixed number c, so that the n-th term [tex]a_n[/tex] is given recursively by
[tex]a_n=a_{n-1}+c[/tex]
Then for n ≥ 2, we have
[tex]a_2=a_1+c[/tex]
[tex]a_3=a_2+c = (a_1+c)+c = a_1 + 2c[/tex]
[tex]a_4=a_3+c = (a_1 + 2c) + c = a_1 + 3c[/tex]
and so on, up to
[tex]a_n=a_1+(n-1)c[/tex]
Given that [tex]a_3=126[/tex] and [tex]a_{64}=3725[/tex], we can solve for [tex]a_1[/tex]:
[tex]\begin{cases}a_1+2c=126\\a_1+63c=3725\end{cases}[/tex]
[tex]\implies(a_1+63c)-(a_1+2c)=3725-126[/tex]
[tex]\implies 61c = 3599[/tex]
[tex]\implies c=59[/tex]
[tex]\implies a_1+2\times59=126[/tex]
[tex]\implies a_1+118 = 126[/tex]
[tex]\implies \boxed{a_1=8}[/tex]

Answer:

Answer:
For the equation y=log(x-k), the domain depends on the value of K. Sliding K moves the left bound of the domain interval. The range and the right end behavior stay the same. For the equation y=log x+k, the domain is fixed, starting at an x-value of 0. The vertical asymptote is also fixed. The range of the equation depends on K.
