The weights of red delicious apples are approximately normally distributed with a mean of 9 Ounces and a standard deviation of 0
Simora [160]

Answer:

The mean of W is 55 ounces.

The standard deviation of W is 4.33 ounces.

Step-by-step explanation:

Let X: weight of a red delicious apple, and B: the weight of the box and packing material.

The distribution that will represent W: the total weight of the packaged 5 randomly selected apples will be also normally distributed.

Applying the property of the mean: E(aX)=aE(X), the mean of W will be:

\mu_W=E(W)=E(5X+B)=5E(X)+E(B)=5*9+10=45+10=55

Applying the property of the variance: V(aX+b)=a^2V(X), the variance of W will be:

\sigma^2_W=V(W)=V(5X+B)=5^2V(X)+V(B)=25*0.75+0=18.75

The mean standard deviation of W will be the squared root of V(W):

\sigma_W=\sqrt{V(W)}=\sqrt{18.75}=4.33

The mean of W is 55 ounces.

The standard deviation of W is 4.33 ounces.

Can someone help me with this
jolli1 [7]

Answer:

  4 sides

Step-by-step explanation:

A lot of math is about pattern matching. Here, you're asked if sides are the same length (one side matches another), if there are right angles (square corners), and if the number of angles or sides is 4.

You might make the observations ...

  <u>pink</u>: 2 pairs of parallel sides that are the same length (4 sides). Adjacent sides are different length.

  <u>orange</u>: all 4 sides are congruent and at right angles

  <u>blue</u>: 2 pairs of parallel sides that are the same length (4 sides). Adjacent sides are different length.

  <u>green</u>: 2 pairs of parallel sides that are the same length--4 sides and 4 right angles. Adjacent sides are different length.

__

The only feature in common is "4 sides."

A) 197 degree<br> B) 261 degree<br> C) 211 degree<br> D) 236 degree
Alik [6]

Answer:

Option D.) 236 degrees

Step-by-step explanation:

Angle GFE is half of the central angle. Measure of central angle is congruent to it's intersecting arc, therefore;

<em>2 * ∠GFE = Arc GE (?)</em>

2 * 118 = Arc GE (?)

<u>236 = Arc GE (?)</u>

Hope this helps!

Which statement is true about the meaning of the equation
timurjin [86]
An equation says that two things are equal. It will have an equals sign (assuming you know what that is)  like this:
7+2=10-1
What the equal says on the left, is equal to the answer on the right. 
Basically, it's a statement saying "equals that"

I don't fully understand your question, but I hope it helped you at least a little.
