Nathan had an infection, and his doctor wanted him to take penicillin. Because Nathan’s father and paternal grandfather were allergic to penicillin, Nathan has a 75% chance of having the same allergy. The doctor performed a skin test to see whether Nathan would react to it. The test is 98% accurate. If the test predicts that Nathan is not allergic to penicillin, what is the probability after the test that Nathan is not allergic to the drug?

For a right triangle, what happens to the value of sine as the angle increases?​

Answers

Answer:

In a right triangle, as the angle increases, the value of the sine increases.

Step-by-step explanation:

Think of the unit circle, a circle with radius 1 unit centered at the origin which is the point with coordinates (0, 0). Draw a radius of the circle from the center, to point (1, 0) on the positive x-axis. The angle formed by this radius and the positive x-axis is 0 degrees. This is an angle in standard position. The endpoint of the radius on the circle has a y-coordinate. The y-coordinate is the sine of the angle. As you choose points on the circle going up from the positive x-axis, the angle formed by the radius connected to the point on the circle and the positive x-axis increases in measure until it coincides with the positive y-axis, where it has a measure of 90 degrees. The sine of the angle is always the y-coordinate of the point on the circle. As the angle increases from 0 to 90 degrees, the y-coordinate increases from 0 to 1. The acute angles of a right triangle can have measures of only between 0 and 90 degrees.

Answer: In a right triangle, as the angle increases, the value of the sine increases.

Steven rolled a 1-6 number cube four times. What is the proballity that Steven rolled an odd number on all four rolls of
the die? (leave your answer as a reduced fraction)

Answers

Answer: 0.0625

Step-by-step explanation:

From the question, Steven rolled a 1-6 number cube four times. This means the 1-6 number cube has numbers 1, 2, 3, 4, 5 and 6. There are 3 odd numbers which are 1, 3 and 5. If the 1-6 number cube is rolled once, the probability will be:

3/6 = 1/2

Since Steven rolled the 1-6 number cube four times, the probability of getting an odd number on all four rolls of the die will be:

= 1/2 × 1/2 × 1/2 × 1/2

= 1/16

= 0.0625

Match each value to the correct entry in matrix AB.

Answers

Answer:

Step-by-step explanation:

The matrix AB is:

[tex]AB=\left[\begin{array}{ccc}50&44&-43\\31&16&7\\37&119&-94\end{array}\right][/tex]

-----------------------------------

This question is solved using multiplication of matrices.

To do this, we multiply the lines of the first matrix by the columns of the second.

-----------------------------------

In this question:

The first matrix is:

[tex]A =\left[\begin{array}{ccc}5&7&2\\4&-1&3\\6&8&-5\end{array}\right][/tex]

The second matrix is:

[tex]B = \left[\begin{array}{ccc}6&11&-4\\2&1&-5\\3&-9&6\end{array}\right][/tex]

------------------------------------

First line:

The first element is the multiplication of the first line of A by the first column of B. So: [tex]AB_{1,1} = 5\times6  + 7\times2 + 2\times3 = 50[/tex]The second element is the multiplication of the first line of A by the second column of B. So:[tex]AB_{1,2} = 5\times11 + 7\times1 + 2\times -9 = 44[/tex]The third element is the multiplication of the first line of A by the third column of B. So:[tex]AB_{1,3} = 5\times -4 + 7\times-5 + 2\times6 = -43[/tex]

------------------------------------

Second line:

Second line of A by each column of B, so:

[tex]A_{2,1} = 4\times6 - 1\times 2 + 3\times3 = 31[/tex]

[tex]A_{2,2} = 4\times11 - 1\times 1 + 3\times (-9) = 16[/tex]

[tex]A_{2,3} = 4\times(-4) - 1\times (-5) + 3\times 6 = 7[/tex]

------------------------------------

Third line:

Third line of A by each column of B, so:

[tex]A_{3,1} = 6\times6 + 8\times 2 - 5\times3 = 37[/tex]

[tex]A_{3,2} = 6\times11 + 8\times 1 - 5\times (-9) = 119[/tex]

[tex]A_{3,3} = 6\times(-4) + 8\times (-5) - 5\times 6 = -94[/tex]

------------------------------------

Thus, the matrix is:

[tex]AB=\left[\begin{array}{ccc}50&44&-43\\31&16&7\\37&119&-94\end{array}\right][/tex]

Answer:

Cans for food drive

Step-by-step explanation:

The header should encapsulate all aspects of the table.

Cans of food are brought by the teachers to be donated to the food drive. Hence the answer should be cans for food drive.

Cans recycled are out of context as the cans of food are for donation as seen in the table, not for recycling.

Favourite food and favourite teacher cannot be measured by the data provided which is which teacher bringing how many cans of food for donation. Hence, these 2 are not the answer as well.

Point M is the midpoint of point A and point B.
What are the coordinates of point B?

Answers

Answer:

the real answer is (8,-4)

Step-by-step explanation:

If the midpoint of the AB is (5.5, 0) then the coordinate of the B will be given as (8, -4).

What is coordinate geometry?

Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.

Point A is at (3, 4) and point M is at (5.5,0).

Point M is the midpoint of points A and B.

Then the point of B is given as

[tex]\rm (x_1,y_1) = (2x-x_2, 2y-y_2)\\\\(x_1,y_1) = (2\times 5.5 - 3, 2\times 0-4)\\\\(x_1,y_1) = (8, -4)[/tex]

The length of a rectangle is $3x+10$ feet and its width is $x+12$ feet. If the perimeter of the rectangle is 76 feet, how many square feet are in the area of the rectangle?

Answers

Answer:

352ft²

Step-by-step explanation:

Given the length of a rectangle = 3x+10

Width of the rectangle = x+12

Perimeter of the rectangle = 76ft

For us to get the area of the rectangle we need to get the value of its length and width.

Given the perimeter of a rectangle P = 2(L+W) where;

L is the length and W is the width, on substitution

76 = 2(3x+10+x+12)

76 = 2(4x+22)

76 = 8x+44

8x = 76-44

8x = 32

x = 32/8

x = 4

Substituting x = 4 into the function of the length and width we have;

Length = 3(4)+10

Length = 22feet

Width = 4+12

width = 16feet

Area of the rectangle = Length * Width

Area of the rectangle = 22feet * 16feet

Area of the rectangle = 352ft²

b. Zhen completes 6 1/2 audiobooks in an hour.
c. Zhen spends 6 1/2 hours working per audiobook.

Answers

Answer:

c. Zhen spends 6 1/2 hours working per audiobook.

Step-by-step explanation:

The table below gives some completed audio lengths and the amount of time Zhen spends on the audiobook.

We observe that from the table, in 6.5 hours, Zhen completes 1 audiobook.

In fact, across the table:

[tex]\dfrac{6\frac{1}{2}}{1}=\dfrac{22\frac{3}{4}}{3\frac{1}{2}}=\dfrac{65}{10}=6\dfrac{1}{2} $ hour per audiobook[/tex]

Therefore, in this situation, 6.5 hours mean that Zhen spends 6.5 hours working per audiobook.

Gloria has a $125,000 home financed with a 30-year loan at 6%. If she wished to pay one extra monthly payment each year, how many months will t take her to pay off her mortgage?

Answers

Answer:

  295 months

Step-by-step explanation:

You want to know the number of months required to pay off a 30-year loan of $125000 at 6% if an extra payment is made each year.

Number of payments

The number of payments required will depend on the actual payment schedule, and the way the lender computes interest due.

The attached calculation shows it takes 319 payments. The assumption is that they are evenly spaced at 13 payments per year (one every 4 weeks), and the interest is computed on the interval between payments.

Number of months

If 13 payments are made per year, the number of years it takes to pay off the loan will be ...

  319/13 = 24 7/13

24 years and 7 months is 295 months.

__

Additional comment

If the first payment is made on Jan 28, and payments are made every 4 weeks, there will be 2 payments in Dec. That is, except for the last month of the year, there will be 1 payment per month.

If regular monthly payments are made, but one of the payments is doubled, the result may be different.

Two numbers are in the ratio 7:5 . When 10 is subtracted from each term , the ratio becomes 3:2 .Find the numbers.

Answers

Answer:

Denote the two numbers: a and b

Two numbers are in the ratio 7:5

=> a/b = 7/5

=> a = (7/5) x b     (1)

When 10 is subtracted from each term , the ratio becomes 3:2

=> (a - 10)/(b - 10) = 3/2

=> 2 x (a - 10) = 3 x ( b - 10)

=> 3 x b - 2 x a = 10

From (1) => 3 x b - 2 x (7/5) x b = 10

             => (1/5) x b = 10

             => b = 50

             => a = (7/5) x b = (7/5) x 50 = 70
