Consider a bell-shaped symmetric distribution with mean of 16 and standard deviation of 1.5. Approximately what percentage of da

fredd [130]

Answer: 95.45 %

Step-by-step explanation:

Given : The distribution is bell shaped , then the distribution must be normal distribution.

Mean : $\mu=\ 16$

Standard deviation : $\sigma= 1.5$

The formula to calculate the z-score :-

$z=\dfrac{x-\mu}{\sigma}$

For x = 13

$z=\dfrac{13-16}{1.5}=-2$

For x = 19

$z=\dfrac{19-16}{1.5}=2$

The p-value = $P(-2$

$0.9772498-0.0227501=0.9544997\approx0.9545$

In percent, $0.9545\times100=95.45\%$

Hence, the percentage of data lie between 13 and 19 = 95.45 %

PLEASE HELP ASAP

7nadin3 [17]

<u>Answer</u>

√7 × √5

√3 × √2

<u>Explanation</u>

√9*√16 = 3 × 4

= 12

= 12/1 ⇒ It is a rational answer.

√7*√5 = √(7×5)

= √35

= 5.916079783.... ⇒ Irrational

√3*√2 = √(3×2)

= √6

= 2.449489743... ⇒ Irrational

4√2*√2 = 4 × √(2×2)

= 4 × √4

= 4 × 2

= 8

= 8/1 ⇒ It is rational

The expressions that would give irrational answers are: √7*√5 and√3*√2

Please Help I Don't Undertand.

If triangles AMN and ABC are similar, then

AM/AB = AN/AC

AM/(AM + MB) = AN/(AN + NC)

Check if this is true:

AM/AB = 21/(21 + 9) = 21/30 = 7/10

AN/AC = 14/(14 + 6) = 14/20 = 7/10

The angle at vertex A is common to both of the triangles.

Then by the side-angle-side (SAS) similarity theorem, the triangles are indeed similar.
