Answer:
[tex]V =\frac{E}{IT}[/tex]
Step-by-step explanation:
You can isolate the "V" variable by dividing by IT on both sides:
[tex]\frac{E}{IT} =\frac{VIT}{IT}[/tex]
On the left, the IT from the top and bottom cancel, leaving you with just V:
[tex]V =\frac{E}{IT}[/tex]
1.On field day, the P.E. coach divides the students into two groups, Positives and Negatives. He wants to have the same amount of students of each group on each side of a rope, to play Tug-of-War.
He uses the following expression to figure out how many students of a certain group he still needs to create an even match.
–5 + 20
Evaluate the expression and write the answer below. Write only a number, either positive or negative. No letters
Answer:
-15
Step-by-step explanation:
because -5 + 20 = -15.
The coach needs 15 negative players to join the negative team in order to get 20 players (which would make the teams even)

Find h.
8 in.
h = [?] in.
6 in.
PLEASE HELP MEEEEE
Answer:
h = [tex]\sqrt{55}[/tex] in
Step-by-step explanation:
A right triangle is formed by h, slant height and radius
Here the legs are h and 6 ÷ 2 = 3, hypotenuse is 8
Using Pythagoras' identity in the right triangle
h² + 3² = 8²
h² + 9 = 64 ( subtract 9 from both sides )
h² = 55 ( take the square root of both sides )
h = [tex]\sqrt{55}[/tex] in

42%
Step-by-step explanation:
Answer:
42%
Step-by-step explanation:
[tex]\frac{21}{50}[/tex] as a percent
[tex]\frac{21}{50}=\frac{y}{100}[/tex]
50 · y = 21 · 100
50y = 2100

1) Solve for Side A
2) Solve for Angle B
Answer:
1) 42.51
2) 39.76
Answer:
solution given;
let
AB=a
AC=b=30ft
AB=c=20ft
<A=115°
By using Cosine rule.
a²=b²+c²-2bc cos angle
a²=30²+20²-2*30*20 Cos 115°
a²=1807.1419
a=√[1807.1419]
a=42.51
Side A is 42.51ft.
Again
Cos B=[tex] \frac{a²+c²-b²}{2ac} [/tex]
Cos B=[tex] \frac{42.51²+20²-30²}{2*42.51*20} [/tex]
Cos B=0.7687

Vijay missed 12 out of his last 16 free throws. Considering this data, how many of his next 20
free-throw attempts would you expect Vijay to miss?
misses
Answer: 15
Step-by-step explanation: i don’t know
Answer:
15
Step-by-step explanation:
The fraction computed shows that the number of his next 20 free-throw attempts that you expect Vijay to miss is 15.
How to solve the fraction?
From the information given, Vijay missed 12 out of his last 16 free throws. The fraction missed will be:
= 12/16
= 3/4
Therefore, the number of his next 20 free-throw attempts that you expect Vijay to miss will be:
= 3/4 × 20
= 15
For a 95% confidence interval what would the sample size need to be as it's most conservative to have a 2% margin of error
Answer:
The size of the sample 'n' = 2401
Step-by-step explanation:
Step:1
Given that the margin of error = 2 % = 0.02
The margin of error is determined by
[tex]M.E = \frac{Z_{0.05} \sqrt{p(1-p)} }{\sqrt{n} }[/tex]
we know that the proportion
[tex]\sqrt{p(1-p)} < \frac{1}{2}[/tex]
Step:2
The margin of error is determined by
[tex]0.02 = \frac{1.96( \frac{1}{2} ) }{\sqrt{n} }[/tex]
[tex]\sqrt{n} = \frac{1.96}{2 X 0.02}[/tex]
√n = 49
Squaring on both sides, we get
n = 49 × 49
n = 2401
Final answer:-
The size of the sample 'n' = 2401
The Basketball Boosters Club plans a pancake supper to raise $1,200. They can serve 240 people. They
will charge $6 for adult tickets and $2 for children's tickets. How many adult and children tickets should
they sell to make $1,200?
A) 160 adult tickets and 80 student tickets
B) 60 adult tickets and 180 student tickets
C) 180 adult tickets and 60 student tickets
D) 200 adult tickets and 40 student tickets
[tex]\huge{ \mathfrak{ \underline{ Answer} \: \: ✓ }}[/tex]
let the number of
adults be x children be yTotal number of people : adults + children
x + y = 240x = 240 - y - [1]Total money earned from adults :
6 × x = 6xTotal money earned from children :
2 × y = 2yTherefore, total money = money earned from each Adult and children.
6x + 2y = 1200 -[2]Now, let's plug the value of x from equation [1] into equation [2]
6 (240 - y) + 2y = 12001440 - 6y + 2y = 1200-4y = 1200 - 1440-4y = - 240y = 60let's plug the value of y in equation [1]
x = 240 - yx = 240 - 60x = 180Hence, we get :
total adults = x = 180total children = y = 60Correct option is C

And orange falls of a display at a store and rolls 5 meters in 2.5 seconds.What is the average speed of the orange
Answer:
The orange moves at 2M/s
5/2.5=2
2meters/secon
The average speed of the orange is 2 m/sec.
Given that, orange falls off a display at a store and rolls 5 meters in 2.5 seconds.
We need to find the average speed of the orange.
What is the average speed formula?Average speed is the mean value of the speed of a body over a period of time. The formula for average speed is needed since the speed of a moving body is not constant and varies across a period of time. Even with varying speeds, the values of total time and the total distance covered can be used, and with the help of the formula for average speed, we can find a single value to represent the entire motion.
The formula for average speed is given as:
Average Speed = Total distance covered ÷ Total time taken
Now, average speed=5/2.5=2 m/sec.
Therefore, the average speed of the orange is 2 m/sec.

A shopper in a grocery store purchases 22 items on average. A store manager believes that the mean is greater than 22. She surveyed a randomly selected group of 36 customers and found that the mean of the number of items purchased was 23.2. The population standard deviation is 3.7 items. At α = 0.05, can it be concluded that the mean is greater than 22 items?
Answer:
The is no significant evidence to conclude that mean is greater than 22
Step-by-step explanation:
H0 : μ = 22
H0 : μ > 22
The test statistic :
(xbar - μ) ÷ (σ/sqrt(n))
xbar = 22.3 ; n = 36 ; μ = 22 ; σ = 3.7
(22.3 - 22) ÷ (3.7/√36)
0.3 ÷ 0.6166666
Test statistic = 0.486
The Pvalue using a Pvalue calculator from Zscore is :
Pvalue = 0.313
α = 0.05
Pvalue > α ; We fail to reject the Null ; The is no significant evidence to conclude that mean is greater than 22
The measures of the angles of a triangle are in the extended ratio 3:3:10 what is the mesasure of the smallest angle?
Answer:
33.75°
Step-by-step explanation:
Given data
Ratio= 3:3:10
combined ratio= 3+3+10= 16
The sum of angles in a triangle is 180°
Hence the smallest angle is represented by the ratio 3
therefore let the angle be x
Applying the part to all method
3/16= x/180
16x= 180*3
16x=540
x= 540/16
x= 33.75°
Hence the smallest angle is 33.75°

stay safe healthy and happy...For what value of x is line / parallel to line m in this figure?
Answer:
132
Step-by-step explanation:
The angle with a measure of 48 degrees and the angle labeled "x" are supplementary angles. Supplementary angles add up to equal 180
This means that we can find the value of the missing angle by subtracting the measure of the known angle from 180
So x = 180 - 48
180 - 48 = 132
Hence, x = 132
