Answer:
58.3% to the nearest tenth.
Step-by-step explanation:
The prime numbers from 1 to 6 are 2,3 and 5.
The probability of a prime number taken from the result of the 300 throws:
= (sum of the frequencies for 2, 3 and 5) / ( total throws)
= (60 + 55 + 60) / 300
= 0.5833 or 58.3%.
1in=4ft
5.25in=5.25*4=21ft
3.5in=3.5*4=14ft
Actual length=21ft, Actual width=14ft
Answer:
The correct option is;
(x, y) → (215·x, 215·y)
Step-by-step explanation:
An enlargement is a form of transformation involving an alteration of the size of the shape. When a shape is to be enlarged, the center of the shape is noted and the enlargement of the dimensions of the shape from that center is by multiplication of each point by the factor of the enlargement or the scale factor.
Therefore, based on the requirement for enlargement, and given the dimension of the point from the center as (x, y) the enlargement then is (215·x, 215·y), where 215 is the scale factor.
To help solve this problem, create a simple equation.
Let x = weekly allowance.
(x/2) + $4 = $11. Subtract 4 from each side
(x/2) = 7. Multiply each side by 2
x = $14.
Joe's weekly allowance is $14
Hey there! :) I only see two questions so I assume you need help with those two if I am not mistaken. So lets start out with number 9!
So, for number 9 we have 5/4- 5/8. Always when you don't have the same denominators( the bottom number) we must find common denominators. So since 4*2= 8 our common denominator is 8! So this is a piece of cake since 5/8 is already in eighths. So we multiply 5*2= 10 and 4*2 = 8 so 5/4 is 10/8. Then we do 10/8- 5/8= 5/8. We only subtract the numerator and the denominator stays the same.
On to number 10! We have 2/3- 2/7. So lets find a set of common denominator. We can do 21, since 3*7= 21 and 7*3= 21! So 2*7= 14 and 3* 7 =21. So for 2/3 we have 14/21. For the 2/7, we do the same thing as before 2*3= 6 and 7*3= 21. So, 2/7= 6/21. Then the last step! Subtract 14/21- 6/21= 8/21. Then we simplify if needed! We don't need to simplify because it can't go any lower.
I hope I helped and explained it well! :D
