Answer:
15 blocks
Step-by-step explanation:
We can use the Pythagorean theorem to solve the right triangle
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
12^2 + 9^2 = h^2
144+81 = h^2
225= h^2
Taking the square root of each side
sqrt(225) = sqrt(h^2)
15 = h
Answer:
x = ±11i
Step-by-step explanation:
x^2 = -121
Take the square root of each side
sqrt(x^2) = sqrt(-121)
sqrt(x^2) = sqrt (-1) *sqrt(121)
We know that the sqrt(-1) is i
x = i ( ±11)
x = ±11i
Answer:
1/6
Step-by-step explanation:
We know that 1/2 are apples and 1/3 are bananas
we also know that
apples+bananas+oranges=1
Which means that
1/2+1/3+oranges=1
Add 1/2 + 1/3 by getting the denominators equal
3/6+2/6=5/6
Which means that 5/6+oranges=1
1-5/6=1/6
1/6
write everything below this
1/2+1/3+oranges=1
1/2+1/3=5/6
5/6+oranges=1
oranges=1-5/6
oranges=1/6
The interval of systolic blood pressure lie between 102 and 118.
<h3>What is systolic
blood pressure?</h3><h3>
Blood pressure is measured using two numbers: The first number, called systolic blood pressure, measures the pressure in your arteries when your heart beats. The second number, called diastolic blood pressure, measures the pressure in your arteries when your heart rests between beats.</h3>
Here, mean blood pressure is 110
and standard deviation is 8
By z table, for 68%,
-1 < z < 1
-1 < (x - μ) / σ < 1
on multiply by σ, we get
-σ < x-μ < σ
on adding μ, we get
-σ + μ < x < σ + μ
-8 + 110 < x < 110 + 8
102 < x < 118
Thus, the interval of systolic blood pressure lie between 102 and 118.
