Step-by-step explanation:
The probability of getting at least 2 twos will be 0.66,
What is probability?Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Probability = Number of favourable outcomes / Number of sample
Given that If a fair die is rolled 5 times, The probability of getting at least 2 twos will be calculated as,
Total outcomes = 5 x 6
Total aoutcomes = 30
Favourable oucomes = 5 x 4 = 20
Probability = 20 / 30
Probability = 0.66
Therefore, the probability of getting at least 2 twos will be 0.66.

The length of a rectangle 5 cm more than its width. If the area of the rectangle is 50 cm2
,
find the dimensions of the rectangle.
Answer:
the length is 10
the width is 5
Step-by-step explanation:
Hey there!
To solve this equation we use the formula
50=5/x
step 1 divide each side by 5
50/5=10
so we can conclude that x (or the width) = 5
then we add 5 (because the length is 5 more then the width)
5+5=10
so length =10 and width = 5

Which system of equations has no solution?
O 5x+5y = 10 and 2x+2y=4
O 3x-6y = 4 and - 4x+8y=7
O 6x+2y = 6 and 7x+3y=9
O 3x-4y = 16 and 2x+3y = 5
Answer:
the first one or the last one
Step-by-step explanation:
5x+5y = 10 and 2x+2y=4
0 = 0
3x-6y = 4 and - 4x+8y=7
0 = 37 / 3
6x+2y = 6 and 7x+3y=9
0 = 3
3x-4y = 16 and 2x+3y = 5

a) − 5 ( 6 n + 6 ) ≤ 30
b) 8 v − 4 ( v − 8 ) > 8
Answer:
a) n ≥ -2
b) v > -6
Step-by-step explanation:
You did not state what you would like us to do with these. I will assume simplify.
a)
− 5 ( 6 n + 6 ) ≤ 30 first, distribute -5
-30 n + -30 ≤ 30 now, add 30 to both sides so we may isolate n our variable
-30 n ≤ 60 now, divide -30 on both sides so we may isolate n completely. When we do this, the sign changes direction
n ≥ -2
b)
8 v − 4 ( v − 8 ) > 8 first, distribute -4 (note: two negatives equal a positive)
8 v - 4v + 32 > 8 now, simplify
4v + 32 > 8 now, subtract 32 from both sides
4v > -24 now, divide both sides by 4 to isolate v
4v > -24
v > -6

Answer:
31.5
Step-by-step explanation:
First we want to find what side NP is equal to. To do that we divide 4 by 12
12/4=3 so side mp=3
next we want to find the scale factor of the rectangles. to do that we divide 4 from 9
9/4=2.25
next we want to find what side st is equal too
to do that we multiply 3 by 2.25
3x2.25=6.75
finally we want to find the perimeter and to do that we do 2(6.75)+2(9)
2(6.75)+2(9)=31.5 so the perimeter of rectangle RSTU is 31.5
hope this helps :)
The set for a school play needs a replica of a historic building painted on a backdrop that is 20 feet long and 16 feet high. The actual building measures 320 feet long by 256 feet high. A stage crewmember writes (x, y) arrow right ( 1/20 x, 1/20y) to represent the dilation. Is the crewmember's calculation correct if the painted replica is to cover the entire backdrop? Complete the explanation.
Answer:
Stage crewmember's calculation is incorrect
Correct = 1/16x 1/16y
Step-by-step explanation:
Given that:
Dimension of backdrop : 20 feets long ; 16 feets high
Actual dimension of building : 320 feets long ; 256 feets high
The correct scale factor can be obtained thus :
Ratio of backdrop dimension to the actual dimension of building
Length : 20 / 320 = 1 /16
Height : 16 / 256 = 1/16
Hence, stage crewmember's calculation of (1/20x ; 1/20y) is incorrect.

Answer:
width = 126 ft
Step-by-step explanation:
I'm going to assume that I am solving for width.
Area = width x length
84 = 2/3 x width
Now divide 84 by 2/3 to get the width (when you divide by a fraction, you actually multiply by its reciprocal, so it is 84 times 3/2)
84 x 3/2 = width
width = 126 feet

Answer:
15x² - 3x - 7
Step-by-step explanation:
(12x² + 2x) - (-3x²+ 5x + 7)
First open the parentheses by applying the distributive property.
To do this, multiply each term you have inside (-3x⅔ + 5x + 7) by -1.
Thus, you would have the following:
12x² + 2x + 3x² - 5x - 7
Add like terms
12x² + 3x² + 2x - 5x - 7
15x² - 3x - 7

Answer:
Step-by-step explanation:
The total number of triangles is 5
The total number of all shapes is 13
The ratio is triangles to total
The ratio is 5 to 13
Note
This problem is not very well defined. Notice the circle at the bottom left. It's less than 1/2 a circle. Question: do you count it or don't you. The answer to that question will influence other partial figures.
All you do is count the total number of figures and the number of triangles. I did count the part circle on the lower left as with the triangles that are missing their tops.

[tex]E(x) = 99[/tex]
Step-by-step explanation:
Given
The attached table
Required
Number of times 3 or 4 will occur
First, we complete the table as follows:
[tex]P(1) + P(2) +......+P(6) =1[/tex]
[tex]0.13 + 0.05 + P(3) + 0.21 + 0.19 + 0.3 = 1[/tex]
Collect Like Terms
[tex]P(3)= 1 -(0.13 + 0.05 + 0.21 + 0.19 + 0.3 )[/tex]
[tex]P(3)= 0.12[/tex]
The expected number of times is:
[tex]E(x)= n * P(x)[/tex]
So, we have:
[tex]E(x) = 300 * (0.12 + 0.21)[/tex]
[tex]E(x) = 300 * (0.33)[/tex]
[tex]E(x) = 99[/tex]
Luis is 0.25 meters shorter than Harry, if Luis is 1.7 meters tall determine Harry’s height.
Answer: 1.95
Step-by-step explanation:
Luis is Harry's height minus 0.25m, which means Harry is Luis' height plus 0.25m.
Luis + 0.25 = Harry
1.7 + 0.25 = 1.95 m

There is a bag filled with 3 blue and 5 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is replaced.
Another marble is taken at random.
What is the probability of getting 2 reds?
Answer: The probability of getting two red marbles is P = 0.141
Step-by-step explanation:
We know that in the bag there are 3 blue marbles and 5 red marbles, then there is a total of 8 marbles in the bag.
The probability of taking at random a red marble is equal to the quotient between the number of red marbles and the total number of marbles, this is:
p = 3/8
Suppose we got a red marble:
Now we replace the red marble we took, so in the bag there are again 3 red marbles and 8 total marbles, then the probability of getting another red marble is again:
q = 3/8
The joint probability (this is, the probability of both events happening) is equal to the product of the individual probabilities, with gives us:
P = p*q = (3/8)*(3/8) = 9/64 = 0.141

On a map drawn to scale, 5 cm represents 30 kilometers. If a line a the same map that connects 2 cities is 7 cm long, what is the distance between the 2 cities?
Answer:
42
Step-by-step explanation:
You can use proportions to solve this problem.
[tex]\frac{5cm}{30km}[/tex]=[tex]\frac{7cm}{xkm}[/tex]
Now just cross multiply.
5cm*Xkm=7cm*30km
you can simplify the cm and km since its multipying.
5x=210
x=42
