Answer:
The equation for height is
Step-by-step explanation:
we are given
An iron ball is bobbing up and down on the end of a spring
So, height function must be trigonometric in nature
So, we can use formula
now, we can find A , B and D
Calculation of A:
maximum height 46 inch
minimum height =18 inch
so,
Calculation of B:
It takes the ball 2 seconds to go from its maximum height to its minimum height
So, half of time period is 2 sec
now, we can use period formula
we can find B
Calculation of D:
Max=46
min=18
now, we can plug these values into formula
and we get
First you have to figure out the total.
42+35+23= 100
So plug it in.
23/100
23%
Your answer is 23%.
Hope this helped ^-^
A) Divide and compare in decimal form -
9/25 = 0.36
4/6=2/7 = 1/4 = 0.25
0.6... > 0.25
B) Fraction to decimal conversion:
4/16 = 2/8 = 1/4 = 0.25
Use long decision or a calculator - 1 divided by four
C) Again, 9/25 = nine divided by twenty-five = 0.36
% Science class)
0.36 = 36%
Move decimal place to right twice and place “%” at the end.
12,176/24 = 1522/3 or 507 1/3
Answer:
129
Step-by-step explanation:
Considering the survey to be representative, you can simply multiply the share of students <em>p</em> preferring “Track & Field” with the whole school population at the same time to estimate the number of such students in the whole school.
First we need to find the relative share <em>p</em> of such answers in the study by dividing it by the sum of answers, assuming that the table is complete for that random sample:
<em>p</em> = 4/(8 + 5 + 4) = 4/17
Then for the whole school we get 550 <em>p</em> ≈ 129.4
