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.

Answer:
N K Q
Step-by-step explanation:
Answer:
She is going 1mph
Step-by-step explanation:
each lap is 1/4 of a mile and 1/4 of an hour so 4 laps = 1 mile and in 1 hour
Answer:
11 hours
Step-by-step explanation:
let he works at first store x hours and at car wash y hours. Then
x+y=25
multiply by 4
4x+4y=100 ...(1)
12x+15y=333
divide by 3
4x+5y=111 ... (2)
(2)-(1) gives
y=111-100=11
From the figure attached with this answer have octagon ABCDEFGH.
We can make a cut to create a plane section in the following shapes:
1. Rectangle
Here ADEH form a rectangle. To make rectangle we take ADEH
2. Octagon
For getting Octagon just cut ABCDEFGH form octagon
3. Triangle
To get triangle cut opposite diagonals. From the figure we can see AOB,BOC,COD,DOE,EOF,FOG,GOH and HOA are triangles.
4. Trapezoid
To get trapezoid ABCD form trapezoid and EFGH form another trapezoid
