Answer:

The best course grade your friend can earn is 0.867 = 86.7%.

The minimum score would your friend would need on the final to earn a 75% for the course is of 0.61 = 61%.

Step-by-step explanation:

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

We have that:

In 70% of the course, the friend has a grade of 81%.

In the other 30%, 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 = 0.7*0.81 + 0.3*1 = 0.867[/tex]

The best course grade your friend can earn is 0.867 = 86.7%.

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 = 0.7*0.81 + 0.3x[/tex]

[tex]0.3x = 0.75 - 0.7*0.81[/tex]

[tex]x = \frac{(0.75 - 0.7*0.81)}{0.3}[/tex]

[tex]x = 0.61[/tex]

The minimum score would your friend would need on the final to earn a 75% for the course is of 0.61 = 61%.

Answer:-61/20

Step-by-step explanation:

Answer:

-3 1/20

Step-by-step explanation:

The denominators share a common multiple of 20.

-5/4 = -25/20

-9/5 = -36/20

-25/20 + -36/20 = -61/20 = -3 1/20

Answer:

[tex]\mathrm{A.} \: \frac{5}{14}\cdot \frac{4}{13}\\[/tex]

Step-by-step explanation:

There are 14 marbles in total, of which 5 of them are red. Therefore, the probability that the first marble she chooses is red is [tex]\frac{5}{14}[/tex].

Since she does not replace the marble, there are now 13 marbles in total, of which 4 are red (she drew one of the red marbles on her first draw). Therefore the probability of her drawing a red marble on her second draw is [tex]\frac{4}{13}[/tex], assuming she draws a red marble on the first draw.

Thus, the probability she draws a red marble on both draws is [tex]\fbox{$\mathrm{A.} \: \frac{5}{14}\cdot \frac{4}{13}$}[/tex].

Hope this helps!

Please mark me brainliest if you can. :)

Explanation: In this expression, +2w, +4w, and +8w are called terms and the numbers in front of the variables, +2, +4, and +8 are called coefficients.

Because the variables are identical,

the three terms in this problem are called like terms.

They can be added together by adding their coefficients.

Since 2 + 4 + 8 is 14, 2w + 4w + 8w is 14w.

Answer:

An equation of the circle with centre (-2,1) and radius 3 is [tex]\mathbf{(x+2)^2+(x-1)^2=9}[/tex]

Option D is correct.

Step-by-step explanation:

Looking at the figure we get centre of circle C (-2,1) and radius of circle r = 3

The equation of circle is of form: [tex](x-h)^2+(x-k)^2=r^2[/tex] where (h,k) is centre and r is radius.

We have centre C (-2,1) so, we have h = -2 and k = 1

We have radius = 3 so, r = 3

Putting values in the equation and finding the required equation:

[tex](x-h)^2+(x-k)^2=r^2\\(x-(-2))^2+(x-1)^2=(3)^2\\(x+2)^2+(x-1)^2=9[/tex]

So,  an equation of the circle with centre (-2,1) and radius 3 is [tex]\mathbf{(x+2)^2+(x-1)^2=9}[/tex]

Option D is correct.

Step-by-step explanation:

The probability that the numbers on the broken calculators are at least 16 will be 0.9997.

Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.

There are 30 calculators numbered 1-30 in a case. If 4 of the calculators are broken.

Then the probability that the numbers on the broken calculators are at least 16 will be

Number of ways to get a sum less than 16 = 1234, 1235, 1236, 1237, 1238, 1239, 2345, 2346 = 8

Probability = 1 – 8 / (³⁰C₄) =  1 – 8/27405 = 0.99970808246
