Answer:

125 degrees

Step-by-step explanation:

We can use triangles to help us. In this case since we need Angle WXY let's use triangle WXY.

Since we are given that Angle ZWY=43, we can use this to determine that Angle XWY=43.

We are also given that XYW=12.

Since angles in a triangle add up to 180 degrees...

Angle WXY = 180-(43+12)

Angle WXY = 180-55

Angle WXY = 125

Using the bar graph, approximately what percent of the total population shown in the table is Cherokee?

seropon [69]

Answer:

about 35%

Step-by-step explanation

added together they = about 890,000. cherokee = about 310,000. 310,000 divided by 890,000 is 0.348.... 890,000 times 35% is like 310,something.

Jessie has a total of 36 coins of dimes and nickels. Total value is $2.35. How many of each kind of coins does he have?

Viktor [21]

There are 2 dollars so that would equal 20 dimes.

Proof:

10 cents = a dime

20 x 10 = 200 = 2 dollars

There are 35 cents to that would equal 3 dimes and 1 nickel.

Proof:

10 cents = a dime

5 cents = a nickel

3 x 10 = 30

1 x 5 = 5

So the final answer would be 23 dimes and 1 nickel.

Suppose that 10% of the undergraduates at a certain university are foreign students, and that 25% of the graduate students are f

Deffense [45]

Answer:

0.6154 = 61.54% probability that the student is an undergraduate

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Foreign

Event B: Undergraduate.

There are four times as many undergraduates as graduate students

So 4/5 = 80% are undergraduate students and 1/5 = 20% are graduate students.

Probability the student is foreign:

10% of 80%

25% of 20%. So

$P(A) = 0.1*0.8 + 0.25*0.2 = 0.13$

Probability that a student is foreign and undergraduate:

10% of 80%. So

$P(A \cap B) = 0.1*0.8 = 0.08$

What is the probability that the student is an undergraduate?

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.08}{0.13} = 0.6154$

0.6154 = 61.54% probability that the student is an undergraduate

A parallelogram has a base of 3.5 units and a corresponding height of 2 units. What is its area?

lara31 [8.8K]

The formula for calculating area of parallelogram is given as:

Area = base x height

So, here in this question,

Base = 3. 5 units

Height = 2 units

Area = 3.5 x 2

= 7 unit^2
