Answer:
The tree is 14 ft. tall.
Step-by-step explanation:
Height of the building/ Height of the tree = Shadow of building/ Shadow of tree
30/x = 75/35 Cross multiply
75x = (30)(35)
75x = 1050
x = 1050/75
x = 14
Answer:
Therefore, the number of female statistics student ages that must be obtained in order to estimate the mean age of all female statistics student is 3625 female statistics student
Step-by-step explanation:
Here, we have
Where:
n = Required sample size
σ = Standard deviation = 18.3
E = Margin of error = 1/2 year
= Critical score from the confidence level = 1.645
Therefore,
Therefore, the number of female statistics student ages that must be obtained in order to estimate the mean age of all female statistics student = 3625 female statistics student.
<span>They use 9 blocks each, a total of 18 blocks.
Bill: 4b + 2
Ron: 8b - 5
To look for the value of b; I assume that both used the same number of blocks.
4b + 2 = 8b - 5
4b - 8b = -5 -2
-4b = -7
-4b/-4 = -7/-4
b = 1.75</span>
Bill: 4b + 2 where b = 1.75 ; then, 4(1.75) + 2 = 7 + 2 = 9
<span>Ron: 8b - 5 where b = 1.75; then, 8(1.75) -5 = 14 - 5 = 9</span>
You can use the Ruffini's rule. The answer using this method is,
And you can see that the multiplicity of the zero x=-4 is 2, and the multiplicity of the zero x=+3 is 1.
Answer:
2261.94671
Step-by-step explanation:
You must first find the circumference of the track. Using 2(pi)r.
Where pi=3.14... and r=radius
you can find the radius by dividing the diameter by 2, 120/2=60
Afterwards you input 60 into the equation. 60*(pi)*2= 376.99111843077515
Using that number you multiply it by 6 because she ran the circumference 6 times. 6*376.99111843077515 = 2261.94671
NOTE: The question may require you to simplify at certain times so answers may vary slightly. EX: pi = 3.14, Circumference = 377
