Kalo randomly surveyed 25 students at his school and found that 19 of them have at least one sibling. Based on these data, how many of the 125 students at his
school would be expected to have at least one sibling?
Answer:
95 students
Step-by-step explanation:
25 students -- 19 have sibling
1 student -- (19/25)
125 students -- (19/25) * 125 = 95
Therefore, 95 students out of 125 are expected to have at least one sibling.
Thenks and mark me brainliest :))
Answer:
95
Step-by-step explanation:
Calculate the experimental probability of choosing a student who has at least one sibling: It is 19/25, or 0.56.
If 125 students are selected, this probability applies. Multiply 125 by 0.56:
0.56(125 students) = 95
95 students could be expected to report having at least one sibling.

Find the 8th Term for the Geometric Sequence for which a1 - 3 and r = -2
Answer:
-384
Step-by-step explanation:
geometric sequence : every new element is generated by multiplying the previous element always with the same number r.
a(n) = a(n-1) * r
a(n) = a(1) * r^(n-1)
so, a(1) = 3, r = -2
a(8) = ?
a(8) = a(1) * r^7 = 3 * (-2)^7
a negative number to an uneven power is again a negative number.
so, (-2)^7 = -128
3 * -128 = -384 = a(8)

Solve for y:
x + 2y = -8
y=-1/2x+4
y=-1/2x-4
y=-2x - 4
y=1/2x-4
Answer:
x + 2y = -8 = y = -4 - 1/2x
y= -1/2x + 4 = y = 4
y= -1/2x - 4 = y = -4
y=-2x - 4 = y = -4
y=1/2x-4 = y = -4
Step-by-step explanation:
(x + 2y = -8 = y = -4 - 1/2x)
[tex]x+2y=-8\\2y=-8-x\\y=-4-\frac{1}{2}x\\[/tex]
In a company there are 33 male and 42 female staff. Calculate the percentage of male and female staffs
Answer: 44%, 56%
Step-by-step explanation:
Given
A company has 33 males and 42 female staff
So, the total staff is the sum of male and female
[tex]\Rightarrow \text{Total=}33+42\\\Rightarrow \text{Total=}75[/tex]
The percentage of male staff is
[tex]\Rightarrow \text{Male }\%=\dfrac{33}{75}\times 100\\\\\Rightarrow \text{Male }\%=44\%[/tex]
The percentage of female staff is
[tex]\Rightarrow \text{female }\%=\dfrac{42}{75}\times 100\\\\\Rightarrow \text{female }\%=56\%[/tex]

Answer:
[tex]10^3[/tex] times
Step-by-step explanation:
Given
Let
[tex]P \to[/tex] Park Crest Middle School
[tex]T \to[/tex] Total
So, we have:
[tex]P = 400[/tex]
[tex]T = 406240[/tex]
Required
Determine the number of times T is greater than P
This is calculated by dividing T by P.
i.e.
[tex]n = \frac{T}{P}[/tex]
So, we have:
[tex]n = \frac{406240}{400}[/tex]
[tex]n = 1015.6[/tex]
Approximate
[tex]n \approx 1000[/tex]
As a power of 10, we have:

Solve for b.
-3b+2.5 = 4
Answer:
b = −0.5
Step-by-step explanation:
Let's solve your equation step-by-step.
−3b+2.5=4
Step 1: Subtract 2.5 from both sides.
−3b+2.5−2.5=4−2.5
−3b=1.5
Step 2: Divide both sides by -3.
-3b/-3 = 1.5/-3
The value of 'b' in the equation given is -0.5
Given the expression for which we could solve for the unknown:
-3b + 2.5 = 4Subtract 2.5 from both sides
-3b = 4 - 2.5
-3b = 1.5
divide both sides by -3 to isolate b
-3b/-3 = 1.5/-3
b = -0.5
Therefore, the value of b in the equation given is -0.5

Find m
Answer:
D. 70.53
Step-by-step explanation:
To solve this problem, one must use the right angle trigonometric rations. These ratios can be used to describe the ratio between the sides and an angle in a right triangle. Please note, each side is named relative to the angle that one is looking at, thus the same side can acquire different names based on the angle one uses to describe it. The trigonometric ratios are the following:
[tex]sin(\theta)=\frac{opposite}{hypotenuse}\\\\cos(\theta)=\frac{adjacent}{hypotenuse}\\\\tan(\theta)=\frac{opposite}{adjacent}[/tex]
In this case, one is asked to find the measure of (<CBA), one is given the hypotenuse (the side opposite the right angle), and the side adjacent to this angle. Therefore, one should use the cosine (cos) function to find this angle.
[tex]cos(\theta)=\frac{adjacent}{hypotenuse}[/tex]
Substitute,
[tex]cos(CBA) = \frac{3}{9}[/tex]
Simplify
[tex]cos(CBA) = \frac{1}{3}[/tex]
Inverse operations,
[tex]CBA=cos^-1(\frac{1}{3})[/tex]
Compute,
m<CBA = 70.53

Answer:
The answer is 52
Step-by-step explanation:
the question is
30 minus 12 divided by 3 times 2
so start with 12 divided by 3 that would equal 4

Kevin is rolling two dice together and adding them up. Which sums should come up the most frequently?
Answer:
7 occurs most frequently.
Step-by-step explanation:
If we roll two dice, we do get sample space as
(1,1) = 1+1 =2 (4,1)=4+1=5
(1,2)= 1+2 =3 (4,2)= 34+2=6
(1,3)= 1+3=4 (4,3)= 4+3=7
(1,4)=1+4=5 (4,4)= 4+4=8
(1,5)=1+5=6 (4,5)= 4+5 =9
(1,6)=1+6=7 (4,6)= 4+6=10
(2,1)= 2+1=3 (5,1)= 5+1=6
(2,2)=2+2=4 (5,2)=5+2 =7
(2,3)= 2+3=5 (5,3) =5+3=8
(2,4)=2+4=6 (5,4) =5+4 =9
(2,5)=2+5=7 (5,5)=5+5=10
(2,6)=2+6=8 (5,6)=5+6=11
(3,1)=3+1=4 (6,1)= 6+1=7
(3,2)=3+2=5 (6,2)=6+2=8
(3,3)=3+3=6 (6,3)=6+3=9
(3,4)=3+4=7 (6,4) =6+4 =10
(3,5) =3+5=8 (6,5)=6+5=11
(3,6)=3+6=9 (6,6)=6+6=12
2 occurs for 1 time
3 occurs for 2 times
4 occurs for 3 times
5 occurs for 4 times
6 occurs for 5 times
7 occurs for 6 times
8 occurs for 5 times
9 occurs for 4 times
10 occurs for 3 times
11 occurs for 2 times
12 occurs for 1 time.

At a location 30m from the base of a flagpole, the angle of elevation is 34 degrees. Determine the height of the flagpole to the nearest meter.
Answer:
20.2 m
Step-by-step explanation:
At a location 30m from the base of a flagpole, the angle of elevation is 34 degrees. Determine the height of the flagpole to the nearest meter.
We solve this question using the Trigonometric function of Tangent
tan θ = Opposite/Adjacent
θ = 34°
Adjacent =30m
Opposite = Height of the flag pole = x
Hence
tan 34 = x/30
Cross Multiply
tan 34 × 30m
= 20.235255505 m
Approximately = 20.2 m
Hence, the height of the flag pole to the nearest meter = 20.2m
