Answer:

A: 4p-16

Hope this helps!

Step-by-step explanation:

you have to multiply the 2 to 4p and 8 which gives you 8p-16 and then subtract 4p and that give you 4x-16.

In a certain country, the mean birth weight for boys is 3.27 kg, with a standard deviation of 0.51 kg. Assuming that the distr

Degger [83]

Answer:

0.066

Step-by-step explanation:

We solve this question using z score formula

z = (x-μ)/σ, where

x is the raw score

μ is the population mean

σ is the population standard deviation

For the question

mean birth weight for boys is 3.27 kg, with a standard deviation of 0.51 kg.

x = 2.5

Hence:

z = 2.5 - 3.27/0.51

z = -1.5098

Probability value from Z-Table:

P(x ≤ 2.5) =P(x < 2.5) = P(x = 2.5) =

=0.065547

Therefore, the proportion of baby boys that are born with a low birth weight is 0.066

Circle A is shown. Secant W Y intersects tangent Z Y at point Y outside of the circle. Secant W Y intersects circle A at point X

timama [110]

Circle A is missing, so i have attached it.

Answer:

∠XYZ = 35°

Step-by-step explanation:

We want to find the angle ∠XYZ in the image attached.

To solve that, we will use the formula in the theorem for angle formed by secants or tangents. Thus;

∠XYZ = ½(arc WZ - arc XZ)

From the image, arc WZ = 175° and arc XZ = 105°

Thus;

∠XYZ = ½(175 - 105)

∠XYZ = ½(70)

∠XYZ = 35°

Express in exponential form 200×75

GREYUIT [131]

Do you mean exponential form as in scientific notation or as in prime factorization.

Now matter I will do both.

As in scientific notation.

200*75

=150*100

=1.5*10000

=1.5*10^4

As in prime factorization.

200*75

=2^3*5^2*3*5^2

=2^3 * 3 * 5^4

Do the one your teacher ask for :) Hope it helps!

Determine whether the sides given would form an acute, obtuse, or right triangle. 7, 7, 13

Brut [27]

Let a = 7 , b = 7, and c = 13. c is always the biggest number.

Acute Triangle is when $c^2 \ \textless \ a^2 + b^2$

Right Triangle is when $c^2 = a^2 + b^2$

Obtuse Triangle is when $c^2 \ \textgreater \ a^2 + b^2$
