Answer: 48oz = $1.68, 32oz = $0.80

Step-by-step explanation:

Let A be the price of the 48oz bottle and B the price for the 32oz bottle.

We are told that:

A = B + $0.88

------

The unit price is defined as the $ per oz.  

Let Au be the unit price for the 48oz size, and

Bu is the unit price for the 32oz size.

[This means that Au*(48) = A and Bu*(32) = B]

We are told that:

Bu + $0.01 = Au

=======

Find the cost of each.

A = B + $0.88

Au*(48) = Bu*(32) + $0.88

Substitute (Bu + $0.01) for Au

(Bu + $0.01)*(48) = Bu*(32) + $0.88

(48Bu + $0.48) = Bu*(32) + $0.88

16Bu + $0.48 =  $0.88

16Bu  =  $0.40

Bu = $0.025

The 32 oz bottle sells for $0.025/oz, or $0.80 a bottle

B = $0.80

Since A = B + $0.88

A =  $0.80 + $0.88

A = $1.68

The unit prices of 48-oz bottle and 32-oz bottle are $0.0183  and $0.01.

One type of operation in mathematics is division. We divide the phrases or numbers into the same number of components during this operation.

Given, 48-oz bottle is $0.88 more than the 32-oz bottle.

That means,

0.88 > 32 x ( 0.01)

0.88 > 0.32

And the unit price of the 32-oz bottle is $0.01 more than the unit price of the 48-oz bottle.

Unit price of 48-oz bottle,

= 0.88 / 48

= 0.0183

Unit price of the 48-oz bottle is $0.0183.

Therefore, $0.0183  and $0.01 are the unit prices of 48-oz bottle and 32-oz bottle.

The height of the mountain using the angles of elevation is 2.346 miles

let

x = distance from the mountain to your current position

h = height of the mountain

Therefore, using trigonometric ratios,

angle of elevation of the current position to the mountain = 8°

angle of elevation of the former position to the mountain = 4.5°

Therefore,

tan ∅ = opposite / adjacent

where

∅ = angle of elevation

tan 8  = h / x

tan 4.5 = h / x + 13

Hence,

x tan 8 = h

(x + 13) tan 4.5 = h

using substitution,

x tan 8  = (x + 13) tan 4.5

x tan 8 = x tan 4.5 + 13 tan 4.5

0.1405408347x = 0.07870170682x + 1.02312218872

0.1405408347x - 0.07870170682x =  1.02312218872

0.0613x = 1.02312218872

x = 1.02312218872 / 0.0613

x = 16.6900489396

x = 16.690 miles

Therefore,

h = 16.6900489396 × tan 8

h = 16.6900489396 × 0.1405408347

h = 2.34561947798

h = 2.346 miles.

The null and alternative hypotheses for the question of whether there is strong evidence to conclude that the standard deviation of performance time exceeds the historical value of 0.75 seconds are as follows:Null hypothesis: σ ≤ 0.75Alternative hypothesis: σ > 0.75.

The test statistic used to test this hypothesis is given by:t = (s/√n) / (σ/√n) = s/σWhere s is the sample standard deviation, n is the sample size, and σ is the population standard deviation (which is hypothesized to be 0.75 in this case).In this particular scenario, there were 17 players and the sample standard deviation of performance was 0.09 seconds.Using the formula, we can calculate the test statistic:t = 0.09/0.75 = 0.12 Since we are testing the alternative hypothesis that the standard deviation exceeds the historical value of 0.75 seconds (i.e., we are interested in the right tail of the t-distribution), we need to find the critical value for a one-tailed t-test with 16 degrees of freedom and a significance level of 0.05.

Using a t-distribution table or a calculator, we find the critical value to be 1.746. Since our calculated test statistic of 0.12 is less than the critical value of 1.746, we fail to reject the null hypothesis.There is not strong evidence to conclude that the standard deviation of performance time exceeds the historical value of 0.75 seconds.

a. The function is D(t) = $2400 - $200t.  b. The domain of D(t) is 0 ≤ t ≤ 12 c. The slope of the function is -200, indicating that the debt decreases by $200 per month. d. It is decreasing.

a. Let:

amount of debt remaining = D(t)

where t represents time in months.

Since Catherine is making equal payments over a 12-month period, each payment will be $2400 divided by 12, which is $200.

The function that represents the amount of debt remaining after t months can be calculated by subtracting the total payments made up to that point from the initial loan amount:

D(t) = 2400 - 200t

b. The domain for this function is the set of non-negative integers up to 12 since Catherine is making payments over a 12-month period. Therefore, the appropriate domain for this function is 0 ≤ t ≤ 12.

c. The slope of the function is the coefficient of the t term, which is -200. The slope of -200 means that for each additional month, the debt decreases by $200.

d. The function is decreasing because the coefficient of the t term (-200) is negative. As time (t) increases, the debt remaining (D(t)) decreases.

When a system of equations has infinitely many solutions, it is considered consistent and dependent.

This means that the equations are not contradictory and there are multiple solutions that satisfy both equations. In contrast, an inconsistent system of equations has no solutions and a consistent, independent system has exactly one unique solution.

For the given system of equations y = x + 5 and y = -5x - 1, we can see that both equations can be rearranged to the form y = mx + b, where m represents the slope and b represents the y-intercept. In this case, the slopes are different (-5 and 1) and the y-intercepts are different (-1 and 5). Therefore, the two lines intersect at a single point and the system has only one solution.

Answer:

The mean and variance of a y is 5 and 9 respectively.

Step-by-step explanation:

Let x1 and x2 be independent random variables.

Suppose the mean and variance of x1 are 2 and 4, respectively. Suppose, the mean and variance of x2 are 3 and 5, respectively. We need to find the mean and variance of y.

Mean of y,

The mean of y is given by the sum of the means of x1 and x2.

Mean of y = Mean of x1 + Mean of x2

Mean of y = 2 + 3

Mean of y = 5

Thus, the mean of y is 5.

Variance of y,

The variance of y is given by the sum of the variances of x1 and x2.

Variance of y = Variance of x1 + Variance of x2

Variance of y = 4 + 5

Variance of y = 9

Some of these extraneous commands are built into programming languages and are known as runtime environments or runtime systems. The environment in which a programme or application is run is known as the runtime environment.

Programs may access all the features they want and operate independently of operating systems thanks to runtime environments, which is one of their main advantages.

False. the statement "If a variable x does not depend on a variable y, both coefficients are equal to zero" is false.

The coefficient of determination (R-squared) and the coefficient of correlation (Pearson's correlation coefficient) are related but distinct measures.

The coefficient of determination, denoted as R², measures the proportion of the variance in the dependent variable (y) that can be explained by the independent variable(s) (x). It ranges from 0 to 1, where a value of 0 indicates that the independent variable(s) do not explain any of the variance in the dependent variable, and a value of 1 indicates that the independent variable(s) completely explain the variance in the dependent variable.

On the other hand, the coefficient of correlation, denoted as r, measures the strength and direction of the linear relationship between two variables (x and y). It also ranges from -1 to 1, where a value of -1 indicates a perfect negative linear relationship, a value of 0 indicates no linear relationship, and a value of 1 indicates a perfect positive linear relationship.

If a variable x does not depend on variable y, it means there is no linear relationship between the two variables. In this case, the coefficient of correlation (r) would be 0, indicating no linear relationship. However, the coefficient of determination (R²) could still be non-zero if there are other independent variables that explain the variance in the dependent variable y.

Therefore, the statement "If a variable x does not depend on a variable y, both coefficients are equal to zero" is false.
