Find the value of x and explain how you found it. Make sure to cite the problem and share what you see before you explain your s

klemol [59]

Answer:

THE VALUE OF X = 3 .

Step-by-step explanation:

From the Δ RQP and Δ TSP ;

⇒ ∠ TPS = ∠ RPQ ( since both are common angle )

⇒ RQ ≈ TS ( parallel lines )

⇒ ∠ PRQ = ∠ PST ( Corresponding angle )

∴ Δ RQP ≅ Δ TSP ( BY ASA RULE )

Now ,

$\frac{RP}{TP} = \frac{QP}{PS}$

$\frac{9 + X}{9} = \frac{6 + 2}{6}$

⇒ X = 3

Find two whole numbers with a sum of 15 and a product of 54

likoan [24]

A+b=15----(1)
a*b=54----(2)

(1) a=15-b ----(3)

put(3) in(2)

(15-b)*b=54
15b-b^2=54
b^2-15b+54=0
(b-9)(b-6)=0
so b=9 or b=6

if b=9 then a=15-9=6
if b=6 then a=15-6=9

answer two numbers are 6 and 9

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 %
