.54 I believe.
20 yellow and 24 blue = 44 cards in all
divide 24 by 44 and you get a .54 repeating decimal.

0.55
Number of favorable outcome/Total number of possible outcome
24/(20+24)

About ______% of the area is between z= -1 and z= 1 (or within 1 standard deviation of the mean)? How do you solve this?

nexus9112 [7]

Answer:

68%

Step-by-step explanation:

<em><u>68-95-99.7% Rule:</u></em>

<em><u /></em>

This is the empirical rule which is used to remember the percentage of values that is within a band of the mean. We say:

68% of the data fall within 1 standard deviation of the mean
95% of the data fall within 2 standard deviation of the mean, and
99.7% of data falls within 3 standard deviations of the mean

Clearly, from the empirical rule, we see that about 68% of the area is between z = -1 and z = 1 (or within 1 standard deviation of the mean)

If the prisms below are similar what is the ratio of the surface area of the smaller prism to the surface area of the larger pri

Ronch [10]

The ratio between the surfaces areas of the two prisms is equal to 6.25.

<h3>How to get the ratio of the surface areas?</h3>

The ratio between the volumes of the prisms is:

$R_v = \frac{375 in^3}{24 in^3} = 15.625$

This number is equal to the cube of the scale of dilation applied to the dimensions of the smaller prism, so the scale factor is:

$\sqrt[3]{15.625} = 2.5$

And the ratio between the areas should be the square of the scale factor, then we will have that the ratio between the surface areas of the two prisms is:

$2.5^2 = 6.25$

Triangle ABC has angle measures as shown. (a) What is the value of x? Show your work. (b) What is the measure of angle C? Show y

Sladkaya [172]

All angles = 180 degrees
3(x-2)+35+52=180
distribute
3x-6+35+52=180
combine like terms
3x+81=180
subtract 81 on both sides
3x=99
divide both sides by 3
x=33
plug in for x
3((33)+2)=
or 180-35-52=93

John and Martha are contemplating having children, but John’s brother has galactosemia (an autosomal recessive disease) and Mart

Rina8888 [55]

<h2>Answer:</h2>

$Probability=\frac{1}{24}$

<h2>Step-by-step explanation:</h2>

As the question states,

John's brother has Galactosemia which states that his parents were both the carriers.

Therefore, the chances for the John to have the disease is = 2/3

Now,

Martha's great-grandmother also had the disease that means her children definitely carried the disease means probability of 1.

Now, one of those children married with a person.

So,

Probability for the child to have disease will be = 1/2

Now, again the child's child (Martha) probability for having the disease is = 1/2.

Therefore,

<u>The total probability for Martha's first child to be diagnosed with Galactosemia will be,</u>

$Probability=\frac{2}{3}\times \frac{1}{2}\times \frac{1}{2}\times \frac{1}{4}\\Probability=\frac{1}{24}$

(Here, we assumed that the child has the disease therefore, the probability was taken to be = 1/4.)

<em><u>Hence, the probability for the first child to have Galactosemia is $\frac{1}{24}$ </u></em>
