Hi there! :)
Answer:
Length = 10.5 m, width = 7 m.
Step-by-step explanation:
Given:
Perimeter, or P = 35 m
Ratio of l to w = 3 : 2
Since the ratio is 3 : 2, let l = 3x, and w = 2x.
We know that the formula for the perimeter of a rectangle is P = 2l + 2w. Therefore:
35 = 2(3x) + 2(2x)
35 = 6x + 4x
35 = 10x
x = 3.5
Plug this value of "x" into each expression to solve for the dimensions:
2(3.5) = w
w = 7 m
3(3.5) = l
l = 10.5 m
Therefore, the dimensions are:
Length = 10.5 m, width = 7 m.
Answer: 0.38
Step-by-step explanation:
Since the variable x is represented by a standard normal distribution, the probability of x > 0.3 will be calculated thus:
P(x > 0.3)
Then, we will use a standard normal table
P(z > 0.3)
= 1 - p(z < 0.3)
= 1 - 0.62
= 0.38
Therefore, p(x > 0.3) = 0.38
The probability of x > 0.3 is 0.38.
Answer:
-42
Step-by-step explanation:
f(8)=6(1-8)
because of that 1-8 is -7 so you times by 6 and get -42
Answer:
2 and a half @ 2.5 inches (sorry i can't type the fraction)
Step-by-step explanation:
- english is my second language so sorry if you doesn't understand:
(1/2, 1/4)=(x,y)
based on the graph shown that each grid on the y axis represents 1/4, that is the smallest scale stood in the y axis.
this means 2 grid= 1/4 x 2 = 1/2 @ 0.5 inches.
since the '5 months-hair-length' is above about 2 grid above 2 inch:
2 inch + 0.5 inch= 2.5 inch
