Answer:

The best course grade your friend can earn is 0.848 = 84.8%.

The minimum score would your friend would need on the final to earn a 75% for the course is of 0.51 = 51%.

Step-by-step explanation:

This is a weighed average problem, in which we multiply each grade by its weight.

We have that:

In 80% of the course, the friend has a grade of 81%.

In the other 20%, he will have x.

What is the best course grade your friend can earn?

This will happen if he earns 100% = 1 on the final test. So

[tex]G = 0.8*0.81 + 0.2*1 = 0.848[/tex]

The best course grade your friend can earn is 0.848 = 84.8%.

What is the minimum score would your friend would need on the final to earn a 75% for the course?

This is x, when the grade is 0.75. So

[tex]0.75 = 0.8*0.81 + 0.2x[/tex]

[tex]0.2x = 0.75 - 0.8*0.81[/tex]

[tex]x = \frac{0.75 - 0.8*0.81}{0.2}[/tex]

[tex]x = 0.51[/tex]

The minimum score would your friend would need on the final to earn a 75% for the course is of 0.51 = 51%.

Answer:

[tex]Blue = 12[/tex]

[tex]Yellow = 9[/tex]

Step-by-step explanation:

Given

[tex]Blue : Yellow = 4 : 3[/tex]

Required

Determine the number of pints of each to make 21 of green paints

First, calculate the total ratio.

[tex]Total = 4 + 3[/tex]

[tex]Total = 7[/tex]

The blue and the yellow pint can be represented individually as:

[tex]Blue = \frac{4}{7} * Green[/tex]

[tex]Yellow = \frac{3}{7} * Green[/tex]

Number of blue paint calculated last week is:

[tex]Blue = \frac{4}{7} * 21[/tex]

[tex]Blue = {4} * 3[/tex]

[tex]Blue = 12[/tex]

[tex]Yellow = \frac{3}{7} * Green[/tex]

[tex]Yellow = \frac{3}{7} * 21[/tex]

[tex]Yellow = {3} * 3[/tex]

[tex]Yellow = 9[/tex]

Answer:

75

Step-by-step explanation:

All the angles would add up to 360

Answer:  0.16 converted to a fraction is 4/25

The probability are for P(h) = 1/2, P(t) = 1/2, P(getting letter P) = 1/12, P(getting a vowel) = 1/2, P(tails then a vowel) = 1/4, P(tails then N) = 1/12, P(heads then D or I) = 1/6.

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

We have a coin tossed, then a letter from the word INDIANAPOLIS is selected at random.

Probability for getting head or tell:

P(h) = 1/2

P(t) = 1/2

The word INDIANAPOLIS has 12 letters with 3I's, 2A's, 2N's, 1D's, 1P's, 1L's, 1O's, and 1S's

Probability for getting letter P:

P(getting letter P) = 1/12

P(heads, then letter P) = P(heads)×P(getting P) = (1/2)(1/12) = 1/24

P(tails) = 1/2

P(getting a vowel) = 6/12 = 1/2

P(tails then a vowel) = (1/2)(1/2) = 1/4

P(tails then N) = (1/2)(2/12) = 1/12

P(heads then D or I) = (1/2)(4/12) = 4/24 = 1/6

Thus, the probability are for P(h) = 1/2, P(t) = 1/2, P(getting letter P) = 1/12, P(getting a vowel) = 1/2, P(tails then a vowel) = 1/4, P(tails then N) = 1/12, P(heads then D or I) = 1/6.

Answer:95

Step-by-step explanation:

95x3=285

There are 95 cards did Steve initially purchase to begin his collection.

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

Steve began a baseball card collection by purchasing some cards.

And, He increased the number of cards in the collection by a constant amount each week after that.

Now, In 3 weeks he collect 285 cards.

Hence, Number of cards to collect in initially is,

⇒ 285/3

⇒ 95

Thus, There are 95 cards did Steve initially purchase to begin his collection.

Solution :

It is given that a psychologist wants to determine the difficulty of the task influences on the estimate of how long people spend working on it.

Now we have to describe a experiment by using a completely randomized design and learn the effect of the difficulty on the estimated time is by randomly assigning 15 students to a Group 1 of easy mazes and other 15 students to the second group 2 of hard mazes. And then we compare the time estimates of the two groups.

Step-by-step explanation:

a) The tax on the burger will be 3% of the cost of the burger.

This means 0.03 of 46.75 (0.03 x 46.75) = $1.40 tax

b) 20% of pre tax bill as tip would be:

0.20 of 46.75 (0.20 x 46.75) = $9.35 tip

c)Total cost of dinner including tax and tip would be:

Original Cost + Tax + Tip

= 46.75 + 1.40 + 9.35

= $57.50 total
