Answer:

p = 0

Step-by-step explanation:

The given equality is p= -2p - 15p

Simplifying, p = (-2-15)p

=> p= -17p

Moving all the terms to the left hand side:

=> p + 17 p =0

=> 18 p =0

The only value of p for which this equality will hold is when p= 0/18 = 0

Validation:

Substituting p = 0 in the original equality:

p= -2p - 15p

LHS = p = 0

RHS = -2p - 15p

= -2*0 -15*0 = 0-0 = 0

So the two sides are equal and the equality is valid for p = 0.

Scores on a certain intelligence test for children between ages 13 and 15 years are approximately normally distributed with μ=10

Tju [1.3M]

Answer: 0.8238

Step-by-step explanation:

Given : Scores on a certain intelligence test for children between ages 13 and 15 years are approximately normally distributed with $\mu=106$ and $\sigma=15$ .

Let x denotes the scores on a certain intelligence test for children between ages 13 and 15 years.

Then, the proportion of children aged 13 to 15 years old have scores on this test above 92 will be :-

$P(x>92)=1-P(x\leq92)\\\\=1-P(\dfrac{x-\mu}{\sigma}\leq\dfrac{92-106}{15})\\\\=1-P(z\leq })\\\\=1-P(z\leq-0.93)=1-(1-P(z\leq0.93))\ \ [\because\ P(Z\leq -z)=1-P(Z\leq z)]\\\\=P(z\leq0.93)=0.8238\ \ [\text{By using z-value table.}]$

Hence, the proportion of children aged 13 to 15 years old have scores on this test above 92 = 0.8238

What’s (3b-5c)(2x+5y) squared

lukranit [14]

Answer: In your problem, you said that they are squared. However, it is not written as squared. We just have to multiply them.

We can use the FOIL method.

(3b - 5c)(3x + 5y)

6bx + 15by - 10cx - 25cy

There are no like terms, so that expression is our final answer.
