Each of the variables t, w, x, y, and z represents a different positive real number. Given the equations below, which of the 4 v
alex41 [277]

Answer:

y has the greatest value.

Step-by-step explanation:

1.23w = t

Divide both sides by 1.23.

w=\frac{t}{1.23}

w=0.813t  --- (1)

1.01x = t

Divide both sides by 1.01.

x=\frac{t}{1.01}

x=0.99t --- (2)

0.99y = t

Divide both sides by 0.99.

y=\frac{t}{0.99}

y=1.01t --- (3)

From (1), (2) and (3), it is clear that y has the greatest value.

Ed takes five 100-point tests in his algebra class. He scores 87, 85 and 87 points on the first three tests. If the scores of hi
trasher [3.6K]

Answer:

Step-by-step explanation:

When we take an average of something, we have to add up all the data on the somethings and then divide by the number of somethings we have. Ed takes 5 tests, and we have scores for them; we also have his current average. What we don't know for sure are 2 of the 5 test scores, but we have enough to determine what they are.

If one test has a score of x, and the other test is 3 points less than that, the score on that last test is x - 3. Putting all of that together into an average problem:

\frac{87+85+87+x+(x-3)}{5}=90 and simplfiying a bit:

\frac{256+2x}{5}=90. Multiply both sides by 5 to get

256 + 2x = 450; subtract 256 from both sides to get

2x = 194 and divide by 2:

x = 97

The one test score was a 97 and the other one, which was 3 less than that, was a 94.

A 12-member jury is to be selected from 15 men and 13 women. Find the probability that this jury has 6 or 7 males.
Bas_tet [7]

Answer:

The right solution is "0.5545".

Step-by-step explanation:

According to the question,

The probability of having 6 or 7 males will be:

= P(6 \ males)+ P(7 \ males)

= \frac{15_C_6\times 13_C_6}{28_C_{12}} + \frac{15_C_7\times 13_C_5}{28_C_{12}}

= \frac{5005\times 1716+6435\times 1287}{30421755}

= \frac{16870425}{30421755}

= 0.5545
