A sample of blood pressure measurements is taken from a data set and those values (mm Hg) are listed below. The values are matc

swat32

Answer:

Step-by-step explanation:

Systolic. Calculate the mean

118+128+158+96+156+122+116+136+126+120+

=1276÷10 = 127.6.

To calculate the median arrange the values from the lowest to the highest.

96,116,118,120,122,126,128,136,156,158.

122+126+2=124.

Disastolic

80+76+74+52+90+88+58+64+72+82= 736÷10=73.6

To calculate the median arrange the values from the lowest to the highest.

52,58,64,72,74,76,80,82,88,90

Median= 74+76=150÷2=75.

Comparison

The Systolic and diastolic blood pressure measures different things, so comparing them is of no use.

It will be good if the relationship between the blood pressure can be investigated because the data are in pairs.

Factor 4n^2 - 5n -6

Allushta [10]

Answer:

(n-2) • (4n+3)

Step-by-step explanation:

4n2-5n-6

Final result :

(n - 2) • (4n + 3)

Step by step solution :

Step 1 :

Equation at the end of step 1 :

(22n2 - 5n) - 6

Step 2 :

Trying to factor by splitting the middle term

2.1 Factoring 4n2-5n-6

The first term is, 4n2 its coefficient is 4 .

The middle term is, -5n its coefficient is -5 .

The last term, "the constant", is -6

Step-1 : Multiply the coefficient of the first term by the constant 4 • -6 = -24

Step-2 : Find two factors of -24 whose sum equals the coefficient of the middle term, which is -5 .

-24 + 1 = -23

-12 + 2 = -10

-8 + 3 = -5 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -8 and 3

4n2 - 8n + 3n - 6

Step-4 : Add up the first 2 terms, pulling out like factors :

4n • (n-2)

Add up the last 2 terms, pulling out common factors :

3 • (n-2)

Step-5 : Add up the four terms of step 4 :

(4n+3) • (n-2)

Which is the desired factorization

Final result :

(n - 2) • (4n + 3)

25 points!!!!!! PLEASE HELP UGHHHHHHHHHHHHHHHHHHHHHHHHHHH

Dovator [93]

Because of the -2 at the end of the function, we know it is shifted down. The +1 means it is shifted left. The answer is the last graph (the one with a y-intercept of -1).

As an estimation we are told 5 miles is 8km Convert 4 km to miles

puteri [66]

Answer: 2.5

Step-by-step explanation:

For this problem, we see that 4km is 1/2 of 8km.

So, we will have to find 1/2 of 5km.

1/2 of 5km = 2.5km

Your answer is 2.5km
