Tim’s goal is to run one marathon in each of the 50 states. To determine the order in which he will run the marathons, he will w

rite the name of each state on a slip of paper and place the slips of paper in a bowl. He will then draw the names of the states one at a time from the bowl until all the slips of paper have been drawn.
If there are 26 states east of the Mississippi River and 24 states west of the Mississippi River, what is the probability that the third state drawn will be east of the Mississippi, given that the first one drawn was east of the Mississippi and the second one drawn was west of the Mississippi?

A) 1/2
B) 13/24
C) 13/25
D) 25/48

This is a conditional probability issue, so the original probability of 26/50 no longer prevails. There have been changes in both the numerator and the denominator.  

The third marathon will be chosen from 48 states, 25 east of the Mississippi and 23 west of the Mississippi. The probability will be 25/48.

so your answer is D) 25/48

I belive the answer is D or B (it is most likely D due to how the probability seems to be more accurate than B)

We know that it is not C because if we times it by two we get 26/50 which is not correct due to the total amount of states.

Answer A is not it because that is a half change when east has a larger chance.

The answer D may be the correct answer as well as for B since they both are more than half the entrees. But B has a little less than probability as compared to the answer D

Find the value of m angle 3-m&lt;1
emmainna [20.7K]

Answer:

The value of m\angle 3-m\angle 1 = 50^{\circ}

Step-by-step explanation:

Vertical Angle theorem: It is about the angles that are opposite to each other.

Also, vertical angle are congruent that means vertical angles are equal.

In the given figure; m\angle 3 and 70^{\circ} are vertical angle

then, by vertical angle theorem,  m\angle3 =70^{\circ}.

Supplementary angle: the sum of the angles whose measure on the straight line is 180 degree.

From the figure, 70^{\circ} , \angle 1 and m\angle 2 =90^{\circ} forms a straight line.

then, by the definition of Supplementary angle;

70^{\circ}+m\angle 1 +m\angle 2=180^{\circ}

Substituting the value of  m\angle 2 =90^{\circ} in above equation:

70^{\circ}+m\angle 1 + 90^{\circ} =180^{\circ} or

160^{\circ}+m\angle 1=180^{\circ}

Simplify:

m\angle 1=180^{\circ}-160^{\circ} =20^{\circ}

therefore,  m\angle 1= 20^{\circ} and m\angle 3=70^{\circ},

the value of m\angle3-m\angle1= 70^{\circ}-20^{\circ} =50^{\circ}.

When finding the margin of error for the mean of a normally distributed population from a sample, what is Alpha, assuming a conf
MArishka [77]

The value of alpha is 0.26, assuming a confidence level of 74%.

<h3>What is the margin of error?</h3>

The significance level α is the probability of making the wrong decision when the null hypothesis is true.

Alpha levels which is also called as significance levels are used in hypothesis tests.

Given

When finding the margin of error for the mean of a normally distributed population from a sample.

The confidence interval = 74% = 0.74.

The value of the alpha is given by;

\rm \alpha =1- Confidence \ interval

Substitute all the values in the formula

\rm \alpha =1- Confidence \ interval\\\\\alpha=1-0.74\\\\\alpha=0.26

Hence, the value of alpha is 0.26, assuming a confidence level of 74%.

Adam buys a bigger turkey than he needs the turkey he buys weighs 7kg the cooking instructions are:
DaniilM [7]
Given:
7 kg turkey

cooking instructions:
over 4kg allow 20 minutes per kg, plus 90 minutes
always leave the turkey to rest for 30 minutes before carving.

7kg * 20 minutes/kg = 140 minutes

140 minutes + 90 minutes = 230 minutes
230 minutes + 30 minutes rest = 260 minutes

260 minutes * 1hr/60 minutes = 4 hours 20 minutes

17:15 is 5:15 pm

17:15 - 4:20 = 12:55 pm

Adam should start cooking at 12:55 pm
