For breakfast, Clarissa can choose from oatmeal, cereal, French toast, or scrambled eggs. She thinks that if she selects a break

fast at random, it is likely that it will be oatmeal. Is she correct? Complete the sentence to explain. Enter the probability in the explanation as a simplified fraction.

Clarissa is not correct. If she were to choose one from the stack at random, it means that she has a 25%, or a 1/4 chance to pick the oatmeal, just like the other breakfast items.

If there were to be more oatmeals than any of the other items, it will heighten the chance of her getting oatmeal which would be the only way to make her statement correct.

Answer:

x=3

Step-by-step explanation:

∠DBC+∠VBC is 180° since it is a straight line, ∠VBC=20x+5

The sum of all angles in a triangle is 180°, 9x-2 + 40° +∠DBC=180°

To find x, you can find ∠DBC first.  *Don't forget BRACKETS

∠DBC=180-(20x+5)

∠DBC=180-(9x-2 + 40°)

Now equal the equations to each other to find x.

180-(20x+5)=180-(40+9x-2)

180-20x-5=180-40-9x+2

175-20x=142-9x

175-142=20x-9x

33=11x

x=33/11

∴x=3

Newborn males have weights with a mean of 3272.8 g and a standard deviation of 660.2 g. Newborn females have weights with a mean
Maksim231197 [3]

The correct option is:   a female who weighs 1500 g

<em><u>Explanation</u></em>

<u>Formula for finding the z-score</u> is:  z= \frac{X-\mu}{\sigma}

Newborn males have weights with a mean(\mu) of 3272.8 g and a standard deviation(\sigma) of 660.2 g.

So, the z-score for the newborn male who weighs 1500 g will be.......

z(X=1500)=\frac{1500-3272.8}{660.2}=-2.685... \approx -2.69

According to the normal distribution table,  P(z=-2.69)=0.0036 = 0.36\%

Now, newborn females have weights with a mean(\mu) of 3037.1 g and a standard deviation(\sigma) of 706.3 g.


So, the z-score for the newborn female who weighs 1500 g will be.......

z(X=1500)=\frac{1500-3037.1}{706.3}=-2.176... \approx -2.18

According to the normal distribution table,  P(z=-2.18)=0.0146 = 1.46\%

As we can see that the <u>probability that a newborn female has weight of 1500 g is greater than newborn male</u>,  so a newborn female has the weight of 1500 g that is more extreme relative to the group from which he came.
