the probability that the animal selected is not a chicken is 4/5 or 0.8, which is the answer.

There are a total of 6 + 4 + 10 = 20 animals on Giovanna's farm.

The probability of selecting a chicken randomly is 4/20 = 1/5, since there are 4 chickens out of 20 animals.

Therefore, the probability of not selecting a chicken is the complement of this probability, which is:

1 - 1/5 = 4/5

what is probability?

Probability is a measure of the likelihood that an event will occur. It is a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. The probability of an event is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

For example, if you flip a fair coin, there are two possible outcomes: heads or tails. The probability of getting heads is 1/2, because there is one favorable outcome (heads) out of two possible outcomes (heads or tails).

Since pink dots is the highest(30) and Purple is second highest so purple must be close to 30.

The requried, height of the purple bar on the relative frequency bar graph is 22, and the answer is (D) 22.

Statistics is the study of mathematics that deals with relations between comprehensive data.

Here,
Since the vertical axis of the bar graph is marked off in percentages, we can determine the height of each bar by multiplying its frequency by 2, since 50 students were surveyed (i.e., 100% of the sample size).

The frequency of the purple color pattern is 11, so its height on the bar graph is 11*2 = 22.

Therefore, the height of the purple bar on the relative frequency bar graph is 22, and the answer is (D) 22.

The sine of an angle and the cosine of its complementary angle are related. Given that sin 36° is 0.588, we can use this information to find the cosine of the complementary angle.

The sine and cosine of complementary angles are related by the identity: sin θ = cos (90° - θ). Since sin 36° is given as 0.588, we can find the cosine of the complementary angle by substituting it into the identity.

cos (90° - θ) = sin θ

cos (90° - θ) = 0.588

Now we can solve for the cosine of the complementary angle by taking the square root of both sides:

cos (90° - θ) = √(0.588)

cos (90° - θ) ≈ 0.767

Therefore, the cosine of the complementary angle is approximately 0.767.

Therefore, approximately 3.375π cubic inches volume of water need to be added to each glass in order to completely fill it when three ice cubes are added.

To determine the volume of water needed to completely fill each water glass, we first need to calculate the volume of one water glass.

Given that the diameter of the water glass is 3 inches and the height is 6 inches, we can find the radius (r) by dividing the diameter by 2:

r = 3 / 2 = 1.5 inches

The volume of a cylinder is given by the formula V = πr^2h, where V represents volume, r represents the radius, and h represents the height.

Substituting the values, we have:

V = π(1.5^2)(6)

V = 2.25π * 6

V = 13.5π cubic inches

So the volume of one water glass is 13.5π cubic inches.

Next, we need to calculate the volume of three ice cubes. Each ice cube has side lengths of 1.5 inches, so the volume of one ice cube is (1.5)^3 = 3.375 cubic inches.

Since we need three ice cubes, the total volume of the ice cubes is 3 * 3.375 = 10.125 cubic inches.

To completely fill the glass with water, we need to find the volume of water that, when added to the volume of the ice cubes, will equal the volume of one water glass.

denote the volume of water needed as V_water.

V_water + 10.125 = 13.5π

To isolate V_water, we subtract 10.125 from both sides:

V_water = 13.5π - 10.125

V_water ≈ 3.375π

Therefore, Chase ran 49/8 miles each day.

To find out how many miles Chase ran each day, we need to divide the total distance he ran (36 3/4 miles) by the number of days (6 days).

First, let's convert the mixed number into an improper fraction. 36 3/4 is equal to (4 * 36 + 3)/4 = 147/4.

Now, we can divide 147/4 by 6 to find the distance he ran each day:

(147/4) / 6 = 147/4 * 1/6 = (147 * 1) / (4 * 6) = 147/24.

Therefore, Chase ran 147/24 miles each day.

To simplify the fraction, we can divide both the numerator and denominator by their greatest common divisor (GCD). In this case, the GCD of 147 and 24 is 3.

So, dividing 147 and 24 by 3, we get:

Based on the survey results, a typical parent would spend around $44 on their child's birthday gift, with a margin of error of approximately $2.9 at a 99% confidence level.

To estimate how much a typical parent would spend on their child's birthday gift, we use the sample mean and standard deviation as estimates of the population parameters. The sample mean of $44 serves as the point estimate for the population mean.

To determine the margin of error, we use the standard error, which is the standard deviation divided by the square root of the sample size. In this case, the standard error is approximately $2.5 (standard deviation of $10 divided by the square root of 20). Multiplying the standard error by the critical value corresponding to a 99% confidence level (z-value of 2.58 for a large sample size) gives us the margin of error.

Therefore, the typical amount spent on a child's birthday gift is estimated to be $44, with a margin of error of approximately $2.9. This means that we can be 99% confident that the true mean amount spent by parents falls within the range of $41.1 to $46.9.

The width of the tent is twice the width of one side which is 10.5 feet.

We know a right-angled triangle has three sides they are -: Hypotenuse,

Opposite and Adjacent.

We can remember SOH CAH TOA which is,

sin = opposite/hypotenuse, cos = adjecen/hypotenuse and

tan = opposite/adjacent.

Given, Brothers Bob and Tom Katz buy a tent that has a center pole 6.25 feet high and the sides of the tent make a 50° angle with the ground.

Here the opposite is the height with the reference angle of 50° and we have to determine the adjacent which is the width of the tent.

∴ tan50° = Height of the pole/width.

1.19 = 6.25/width.

width = 6.25/1.19.

width = 5.25 feet.

But the total width of the tent will be twice as we have obtained only one side width.

The height of the pile is increasing at a rate of 4.8 feet per minute when the pile is 25 feet high.

The formula for the volume of a cone is V = (1/3)πr^2h.

Since the base diameter and height are always the same, we can express the volume as

V = (1/3)π(r^2)(h^2).

Taking the derivative with respect to time t, we get

V/dt = (2/3)πrh(dh/dt) + (1/3)πr^2(dh/dt).
Since r = h/2, we can substitute this into the equation and simplify to get

dV/dt = (1/3)π(h^3/2)(dh/dt + h(dh/dt)).

Plugging in the given values, we get

30 = (1/3)π(625/4)(dh/dt + 25(dh/dt)), which gives us dh/dt = 4.8 ft/min when h = 25 ft.

There is a strong positive linear relationship between x and y with a slope coefficient of 1.535 and an intercept of 1.558.

The correlation coefficient and coefficient of determination both indicate a high degree of association between the two variables, and the t-test and confidence interval for the slope coefficient confirm the significance of this relationship.

The engineer fitted the straight line to the given data using the method of Least Squares. The equation of the line is y = 1.535x + 1.558, where x represents the independent variable and y represents the dependent variable.

The correlation coefficient between x and y is r = 0.9884, which indicates a strong positive correlation between the two variables. The coefficient of determination, r^2, is 0.977, which means that 97.7% of the total variation in y is explained by the linear relationship with x.

To test the significance of the slope coefficient, t-test can be performed using the formula t = b/SE(b), where b is the slope coefficient and SE(b) is its standard error. In this case, b = 1.535 and SE(b) = 0.057.

Therefore, t = 26.93, which is highly significant at any reasonable level of significance (e.g., p < 0.001). This means that we can reject the null hypothesis that the true slope coefficient is zero and conclude that there is a significant linear relationship between x and y.

In addition to the t-test, we can also calculate the confidence interval for the slope coefficient using the formula:

b ± t(alpha/2)*SE(b),

where alpha is the level of significance (e.g., alpha = 0.05 for a 95% confidence interval) and t(alpha/2) is the critical value from the t-distribution with n-2 degrees of freedom (where n is the sample size).

For this data set, with n = 7, we obtain a 95% confidence interval for the slope coefficient of (1.406, 1.664).

The value of q is -27.

Recall Vieta's Formulas, which state that for a quadratic equation \(ax^2\) + bx + c = 0 with zeroes alpha and beta, the sum of the zeroes is equal to -b/a, and the product of the zeroes is equal to c/a.

In our equation \(x^2\) - 3x + q, the sum of the zeroes alpha and beta is -(-3)/1 = 3.

We are given that 2 alpha + 3 beta = 15. Substitute alpha = (15 - 3 beta)/2 into the equation.

Replace the value of alpha in the sum of zeroes equation: (15 - 3 beta)/2 + beta = 3.

Simplify the equation by multiplying both sides by 2: 15 - 3 beta + 2 beta = 6.

Combine like terms: 15 - beta = 6.

Subtract 15 from both sides: -beta = -9.

Multiply both sides by -1 to solve for beta: beta = 9.

Substitute the value of beta into the sum of zeroes equation: alpha = (15 - 3 * 9)/2 = -3.

Since we have the values of alpha and beta, we can find q using the product of the zeroes formula: q = alpha * beta = -3 * 9 = -27.
