In baseball, each time a player attempts to hit the ball, it is recorded. The ratio of hits compared to total attempts is their batting average. Each player on the team wants to have the highest batting average to help their team the most. For the season so far, Jana has hit the ball 12 times out of 15 attempts. Tasha has hit the ball 9 times out of 10 attempts. Which player has a ratio that means they have a better batting average?
A. Tasha, because she has the lowest ratio since 0.9 > 0.8
B. Tasha, because she has the highest ratio since 27 over 30 is greater than 24 over 30
C. Jana, because she has the lowest ratio since 0.9 > 0.8
D. Jana, because she has the highest ratio since 27 over 30 is greater than 24 over 30
Tasha has the highest batting average because 0.9(27/30) is greater than 0.8( 24/30 ) ( optionD)
What is ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as: 1 : 3 (for every one boy there are 3 girls) 1 / 4 are boys and 3 / 4 are girls.
The batting average for Jana is 12/15 = 0.8
The battling average for Tasha is 9/10 = 0.9
The battling average of Tasha is higher than that of Jana
0.6 can also be in form of 6/10
0.9 can also be in form of 9/10
therefore 8/10 = 24/30 and
9/10 = 27/30
Therefore Tasha has the highest batting average because 27/30 is greater than 24/30

How much of the circle is shaded? Write your answer as a fraction in simplest form.
Answer:
3/8
Step-by-step explanation:
In these type of problems, I like making all of my denominators the same.
1/8 is good.
1/2 is half. 4/8 is also half. I'll use 4/8 because 1/8 also has the 8
A whole circle is 100%, which is 1/1. It's also 8/8
To find the shaded area, we'll first add 1/8 and 4/8. That equals 5/8. We just have to add nominators/top now because the denominator/bottom is the same
Now we'll subtract 8/8 from 5/8. Again denominator is the same, so we only need to subtract the top

The measure of the side length CL is equal to 9m using trigonometric ratio of cosine 60° for thy right triangle ACL
What are trigonometric ratiosThe trigonometric ratios involves the relationship of an angle of a right-angled triangle to ratios of two side lengths. Basic trigonometric ratios includes; sine cosine and tangent.
Angle m∠BAC = 180° - (m∠C + m∠ABC)
m∠BAC = 180° - (90° + 30°)
m∠BAC = 60°
line AL is an angle bisector so;
m∠CAL = 30° and m∠BAL = 30°
which implies triangle ∆ALB is an isosceles with line LB = AL = 18m
considering the right triangle ∆ACL;
angle m∠L = 180° - (90° + 30°)
m∠L = 60°
cos 60° = CL/18 {adjacent/hypotenuse}
1/2 = CL/18m {cos 60° = 1/2}
CL = 18m/2 {cross multiplication}
CL = 9m
Therefore, the side length CL is equal to 9m using trigonometric ratio of cosine 60° for the right triangle ACL.

a sonar operator on a ship detects a submarine at a distance of 500 meters and an angle of depression of 40 degrees. how deep is the submarine?
To determine the submarine's depth, you would need to use trigonometry. The angle of depression (40 degrees) and the distance from the ship to the submarine (500 meters) form a right triangle.
You can use the tangent function (tan) to find the opposite side (depth) of the triangle, given the adjacent side (distance) and the angle.
Depth = distance * tan(angle of depression)
Depth = 500 meters * tan(40 degrees)
You can use a calculator or table to find the value of tan(40 degrees), which is approximately 0.8391.
Depth = 500 meters * 0.8391
Depth = 419.55 meters
So the submarine's depth is 419.55 meters deep.
Right triangles can be used to represent word problems involving angles of elevation and depression. When working right triangles, the trigonometric rates are used to break for the right triangle's sides and angles representing the problem.

For the angle of depression (40 degrees) and the distance from the ship to the submarine (500 meters) the submarine's depth will be 419.55 meters
Right triangles can be used to express word problems with elevation and depression angles. When working with right triangles, trigonometric rates are employed to break for the sides and angles of the right triangle that represent the problem.
Trigonometry would be required to estimate the depth of the submarine.
Given the neighbouring side (distance) and the angle, you can use the tangent function (tan) to get the opposite side (depth) of the triangle.
Depth = distance multiplied by tan (angle of depression)
500 metre depth * tan (40 degrees)
You may determine the value of tan(40 degrees) using a calculator or a table, which is about 0.8391.
So, the value of the depth = 500 meters * 0.8391

how do i go about this
The largest possible value for the probability of A4 is 0.1.
How to determine the largest probability of A4?From the question, we have the following parameters that can be used in our computation:
A1, A2, A3, and A4, be events from a common sample space.
We know that A1 and A2 occur simultaneously with a probability of 0.1, which means that the probability of A1 or A2 occurring is 0.3
We also know that events A1, A2, and A3 each occur with probability 0.3.
So, the probability of A4 occurring is equal to 1 minus the probability of the other three events occurring.
Therefore, the largest possible value for the probability of A4 is:
P(A4) = 1 - (0.3 + 0.3 + 0.3)
P(A4) = 1 - 0.9
P(A4) = 0.1
So, the maximum value that the probability of A4 can take is 0.1.

1. The probability of selecting exactly one tank with high-viscosity material is 0.
2. The probability of selecting at least one tank with high-viscosity material is 1.
3. The probability of selecting exactly one tank with high-viscosity material and exactly one tank with high impurities is 0.25.
1. The probability of selecting exactly one tank with high-viscosity material is calculated by the binomial distribution formula, P(X = n) = (nCx)p^x(1-p)^n-x, where n is the number of trials, x is the number of successes, and p is the probability of success. In this case, n = 4, x = 1, and p = 24/24 = 1. Therefore, P(X = 1) = (4C1)1^1(1-1)^4-1 = 0.
2. The probability of selecting at least one tank with high-viscosity material is calculated by the complement rule, P(X > 0) = 1 - P(X = 0). In this case, P(X > 0) = 1 - (4C0)1^0(1-1)^4-0 = 1.
3. The probability of selecting exactly one tank with high-viscosity material and exactly one tank with high impurities is calculated by the binomial distribution formula, P(X = n) = (nCx)p^x(1-p)^n-x, where n is the number of trials, x is the number of successes, and p is the probability of success. In this case, n = 8, x = 2, and p = 24/24 = 1. Therefore, P(X = 2) = (8C2)1^2(1-1)^8-2 = 0.25.

An individual data point's residual is a measurement of how well a line fits it. Take a look at this straightforward data set with a line of fit through it.
The discrepancy between expected values of y (the dependent variable) and actual values of y is the residual for each observation. Relative to projected and actual y values, residual is equal to yi. Actual y value minus expected y value equals residual; therefore, r I = y I y i.
