Supplementary angles are those whose sum is equal to 180° while those that are complementary are those whose sum is equal to 90°. Since, we are given that bre is the complement of itself, its measure can be calculated through the equation,
m∠bre + m∠bre = 90°
m∠bre = 45°

Then, for the relationship of bre and tap, we have the equation,
m∠bre + m∠tap = 180°
45° + m∠tap = 180°
m∠tap = 135°

The measure of tap is equal to 135°.

A card is drawn from a deck of cards numbered one through twenty. The card is NOT replaced and another card is drawn. Find the p

Bess [88]

Answer:

B) P(two prime numbers are drawn in a row) = 14/95

Step-by-step explanation:

Total cards in the deck = 20

Total prime numbered cards in deck = { 2, 3, 5, 7, 11, 13, 17, 19} = 8 cards

So, Probability of picking two prime cards from deck (without replacing)

= Probability of picking first prime card x Probability of picking second prime card

P( picking first prime card ) = $\frac{\textrm{Total prime cards in the deck}}{\textrm{Total available cards}}$

= $\frac{8 }{20} = \frac{2}{5}$

P( picking second prime card ) = $\frac{\textrm{Total prime cards in the deck}}{\textrm{Total available cards}}$

= $\frac{7}{19}$

Hence, the total probability = $\frac{2}{5} \times \frac{7}{19} = \frac{14}{95}$

or, B) P(two prime numbers are drawn in a row) = 14/95

The data on the scores obtained by students in five different entrance exams have been collected from 50 colleges and they are p

Westkost [7]

Answer:

Step-by-step explanation:

1. Add data into excel and name both the columns

2. Select top cell and press Ctrl+T to convert data into table

3. Click on any cell on the table and click pivot table in the 'Insert' tab. You will get a pivot table frame.

a. Which exam did most students attempt?

i. Move 'Test name' field to row in the pivot table. Also move test scores field to the value table.

ii. This by default will give you the sum of scores. Click on the field under 'value' table and change it from 'sum of values' to 'count of values'

The answer is GMAT taken by 13 students

b. Which exam has the highest average score?

i. From the pivot table created in part a, change the field setting to 'Average' instead of count.

The answer is GMAT with 499.07 average

c. Use the pivot table to determine the exam attempted by the student with highest score

i. In the pivot created above, change field setting to 'Max'

The answer is MCAT with 589

What is the exam attempted by the student with lowest score.

i. Change the field setting in the pivot to 'Min'

The answer is GRE with 267

Noel Devine bought a new dishwasher for $320. He paid 20 down and made 10 monthly payments of $34 what actual yearly interest ra

Nookie1986 [14]

IN finding the interest we need to use the following formula:
Interest= Principal x Rate x Time or I= PRT
Substitute values: I= [$20 + ($10 x $34)] -320 =$40
P= $320
R=?
T=10 months/year
I=PRT
Since R is a missing term, we will solve for R using this formula: R=I/PT
R= [$20 + ($10 x $34)-320] / ($320 x 10 months)
T=10 months÷12 months=0.83
R= ($40)/ $320 X 0.83
R= 40/ 265.6
R=15.06024096

Alice chose five positive integers and found that their product was even. What is the maximum number of odd integers she could h

Nat2105 [25]

Answer:

In order for a product to be even, at least one factor must be even (so that the product is divisible by 2). The minimum number of even integers she could have chosen is 1, so the maximum number of odd integers she could have chosen is 4 :)
