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.

What is the value of the x variable in the solution to the following system of equations? (5 points) 2x − 3y = 3 5x − 4y = 4 Sel
Rama09 [41]

Answer:

D. There is no x value as there is no solution to this system

Step-by-step explanation:

2x − 3y = 3                                  5x − 4y = 4

5x - 4y = 4               -4y = -5x + 4                         y = 5/4x - 1

2x - 3(5/4x - 1) = 3

2x - 15/4x + 3 = 3

-7/4x = 0

x = 0
