How many cups of yellow paint should you mix with 3 cups of blue paint to make the same shade green? Explain.
Answer:
You should mix 15 cups of yellow paint, because it takes 5 cups of yellow paint + one cup of blue paint to make the same green. Since there's 3 cups of blue paint, multiply that by 5, and you get 15.

Create a binomial probability experiment with the data from the public opinion poll experiment. Use the probability of success and failure from the experiment. Calculate the probability of the number of successes in 100 random tests. For example, if the probability of success is 0.20 and the number of trials is 100, then the number of successes is 20.
give a real answer please this is important for my grade
Step-by-step explanation:
How do you calculate number of successes?
Example:
Define Success first. Success must be for a single trial. Success = "Rolling a 6 on a single die"
Define the probability of success (p): p = 1/6.
Find the probability of failure: q = 5/6.
Define the number of trials: n = 6.
Define the number of successes out of those trials: x = 2.
Binomial probability distribution for the given set of data is
[tex]\ 100C_{x[/tex][tex]( 0.20)^{x} (0.80)^{100-x}[/tex].
What is binomial probability distribution?"Binomial probability distribution is the representation of a probability with only two outcomes success and failure under given number of trials."
Formula used
Binomial probability distribution is given by
[tex]\\n{C}_{x}p^{x}q^{n-x}[/tex]
n= number of experiments
x = 0, 1, 2, 3,.......
p = probability of success
q = probability of failure
According to the question,
Number of trials 'n' = 100
Probability of success 'p' = (20 / 100)
= 0.20
Probability of failure 'q' = 1 - p
= 1 - (20/100)
= (80 / 100)
Substitute the value in the formula we get
Required probability = [tex]\ 100C_{x[/tex][tex]( 0.20)^{x} (0.80)^{100-x}[/tex]
Example:
Tossing a coin 6 times getting exactly two heads.
Number of trials 'n' = 6
Number of heads 'x' =2
Only two possible outcomes head or tail
Probability of getting head 'p' = 1 / 2
Probability of not getting head 'q' = 1 /2
Required probability = [tex]\ 6C_{2[/tex] (1/2)²(1/2) ⁶⁻²
=[tex]\ 6C_{2[/tex] (1/2)⁶
Hence, binomial probability distribution for the given set of data is
[tex]\ 100C_{x[/tex][tex]( 0.20)^{x} (0.80)^{100-x}[/tex]

Solve for z: 5(2z-7) = -2z + 7
A. z = 7/2
B. z= 21/4
C. z= -7/2
D. z= - 7/3
Answer:
A. z = 7/2
Step-by-step explanation:
First, distribute the 5 into 2z and 7 to get 10z - 35 for the left side and the right side should be the same. Add 2z on both sides to get to this equation 12z - 35 = 7. Add 35 on both sides to get 12z = 42. Divide 12 on both sides, since it is an improper whole number, the fraction would be left as 42/12. However, both numbers can be divisible by 6 leaving your z value as 7/2.
Answer:
The answer is
[tex] \frac{7}{2} [/tex]
Step-by-step explanation:
1. Distribute
[tex]5(2z - 7) = - 2z + 7 \\ 10z - 35 = - 2z + 7[/tex]
2. Solve
[tex]10z - 35 = - 2z + 7 \\ \frac{+ 2z \: \: \: \: \: \: \: \: \: \: \: \: \: \: = + 2z \: \: \: \: \: \: \: }{12z - 35 = 7} \\ \frac{ \: \: \: \: \: \: \: \: \: \: \: \: \: + 35 = + 35}{12z = 42 } \\ \\ \frac{12z}{12} = \frac{42}{12} \\ \\ z = 3.5 \: or \: \frac{7}{2} [/tex]

a train covers 165km in 1.5 hours find the constant variation
Answer:
110 km/hour
Step-by-step explanation:

The perimeter of a rectangle is 70 inches. If its length is four times its width, find the dimensions. Write an equation and solve.
Answer: Length = 28cm
Width = 7cm
Step-by-step explanation:
Let the width be represented by x.
Since the length is four times its width. Therefore, the length would be:
= 4 × x = 4x
The perimeter of a rectangle is calculated as:
= 2(length + breadth)
Therefore, 2(4x + x) = 70
2(5x) = 70
10x = 70
x = 70/10
x = 7
Therefore, width = 7cm
Length = 4x = 4 × 7 = 28cm

30. Find the equation of straight line whose slope
is 3 times and y-intercept is double of the line
2x - 3y = 4.
Step-by-step explanation:
gradient/slope = 3
y-intercept
2x - 3y = 4
3y = 2x - 4
y = 2/3x - 4/3
so y-intercept is double -4/3 so... -4/3x2 = -8/3
the equation of the line is
y = 3x - 8/3 or 9x - 3y = 8
Answer:
3y=2x-8
Step-by-step explanation:
when y intercept x=0
2(0)-3y=4
-3y=4
y=-4/3
when x intercept y=0
2x -3(0)=4
2x =4
x=2
point (2,-4/3)
gradient
-3y=-2x +4
y=2x/3-4/3
gradient=2/3
equation
y+4/3=2/3(x-2)
3y+4=2x-4
3y=2x-8
