A certain dataset of systolic blood pressure measurements has a mean of 80 and a standard deviation of 3. Assuming the distribut

ion is bell shaped and we randomly select a measurement.
Required:
a. What percentage of measurements are between 71 and 89?
b. What is the probability a person's blood systolic pressure measures more than 89?
c. What is the probability a person's blood systolic pressure being at most 75?
d. We should expect 15% of patients have a blood pressure below what measurement?
e. Would it be unusual for 3 patients to have a mean blood pressure measurement of more than 84? Explain.

What is the height of a solid box that has a mass of 438 g, a destiny of 2.17 g/cm, a length of 40 cm, and a width of 20 cm.​
lapo4ka [179]
  • <em>Answer:</em>

<em>h ≈ 0.25 cm</em>

  • <em>Step-by-step explanation:</em>

<em>Hi there !</em>

  • <u><em>density formula</em></u>

<em>d = m/V</em>

<em>V = l×w×h</em>

<em>replace</em>

<em>2.17 = 438/(40×20)×h</em>

<em>2.17 = 438/800×h</em>

<em>2.17×800×h = 438</em>

<em>1736h = 438</em>

<em>h = 438/1736</em>

<em>h ≈ 0,25 cm</em>

<em>Good luck !</em>

The vertices of a triangle are located at L(4, –3), M(1, –3), and N(1, 0). What is the approximate perimeter of triangle LMN?
adelina 88 [10]

Answer:

Step-by-step explanation:

you need to find the distance between points L, M, N to know the length of sides LM, MN, NL

use the distance formula

d= √(x2-x1)² +(y2-y1)², where the points are (x1, y1) and (x2, y2)

LM = √(4-1)² + (-3- -3)² = √3² + 0² = 3

MN = √(1-1)² + (-3-0)² = √0² + 9 = 3

NL = √(4-1)² + (-3-0)² = √3² + 9 = √18 = 3√2

The perimeter is LM+MN+NL = 3+3+3√2 = 6+3√2 ≈ 10.243

I need help please and thank you
MAVERICK [17]

Answer:

A

Step-by-step explanation:

5x - 10 > 15

Add 10 to each side

5x-10+10 >15+10

5x > 25

Divide each side by 5

5x/5 >25/5

x>5

There is a open circle at 5 and the line goes to the right since x is bigger
