The lengths of human pregnancies are normally distributed with a mean of 268 days and a standard deviation of 15 days. What is t

AfilCa [17]

Answer: A. 0.0164

Step-by-step explanation:

Given : The lengths of human pregnancies are normally distributed with a mean $\mu=268\text{ days}$

Standard deviation : $\sigma=15\text{ days}$

Let X be the random variable that represents the length of pregnancy of a randomly selected human .

z-score : $z=\dfrac{X-\mu}{\sigma}$

For X = 300

$z=\dfrac{300-268}{15}\approx2.13$

Now, the probability that a pregnancy last at least 300 days will be :-

$P(X\geq300)=P(z\geq 2.1333)=1-P(z$

Hence, the probability that a pregnancy last at least 300 days =0.0164

Kyleigh put a large rectangular sticker on her notebook.the height of the sticker measures 10 cm. the base is half as long as th

mixer [17]

Hey there! Welcome to Brainly! I'm happy to help you!

When we are talking about the height and base, let's use the variables h and b. With the information we have been given, we can make the following equations below.

h=10 (the height is 10)

b=h/2 (base is half as long as the height)

We see that h is equal to ten. b is equal to h divided by two, so it is therefore ten divided by 2! We take the value for h and the plug it into the second equation!

b=10/2

b=5

So, we now know that the height is 10 cm and that the base is 5 cm. However, we need to find the area. To find the area of a rectangle, we just multiply the base by the height!

10(5)=50

Therefore, the area of the sticker is 50 cm².

I hope that this helps! Have a wonderful day!

Which triangles are similar?

likoan [24]

Answer:

option B) ΔABE ∼ ΔADC

Step-by-step explanation:

The picture of the question in the attached figure

we know that

If two triangles are similar, then its corresponding sides are proportional and its corresponding angles are congruent

In this problem

Triangles ABE and ADC are similar by AA Similarity Theorem

because

m∠ ABE≅m∠ADC

m∠ BAE≅m∠DAC

The corresponding sides are

AB and AD

BE and DC

AE and AC

$\frac{AB}{AD}=\frac{BE}{DC}=\frac{AE}{AC}$
