Zachary' Diner old 28 milkshake with whipped cream on top and 72 milkshake without whipped cream,  percentage of the milkshake had whipped cream is 28%.

Zachary ordered 28 milkshake with whipped cream on top and 72 milkshake without whipped cream.

So total number of milkshake is 100

So percentage of milkshake had whipped cream will be,

28/100 x 100

=28%

A percentage is a ratio or fraction where the full value is always 100. Sam, for instance, would have received 30 out of a possible 100 points if he had received 30% on his arithmetic test. In ratio form, it is expressed as 30:100 and in fraction form as 30/100.

Finding the percentage of a whole in terms of 100 is what percentage calculation refers to. A percentage can be found in one of two ways:

Null hypothesis: proportion of errors = 46%. Alternative hypothesis: proportion of errors ≠ 46%. Hypothesis test done using sample proportion and significance level of 0.05.

What is null hypothesis ?

The null hypothesis is a characteristic arithmetic theory suggesting that no statistical relationship and significance exists in a set of given, single, observed variables between two sets of observed data and measured phenomena.

To test if there is sufficient evidence to refute the hospital director's claim, we would perform a hypothesis test. The test statistic in this case would be the sample proportion of lab reports with errors (95 errors out of 250 total lab reports), and we would compare this to the null hypothesis value of 46%. The p-value for this test represents the probability of observing a sample proportion as extreme or more extreme than the observed proportion, given that the null hypothesis is true.

If the p-value is less than the significance level of 0.05, we would reject the null hypothesis, which means we have sufficient evidence to conclude that the proportion of lab reports with errors is not equal to 46%. On the other hand, if the p-value is greater than or equal to the significance level of 0.05, we would fail to reject the null hypothesis, which means we do not have sufficient evidence to conclude that the proportion of lab reports with errors is different from 46%.

Null hypothesis: proportion of errors = 46%. Alternative hypothesis: proportion of errors ≠ 46%. Hypothesis test done using sample proportion and significance level of 0.05.

When the sample sizes are large, a chi-squared test (also known as a chi-square or 2 test) is a statistical hypothesis test used in the study of contingency tables. To put it another way, the main purpose of this test is to determine if two categorical factors (two dimensions of the contingency table) have independent effects on the test statistic (values within the table).

The test, specifically Pearson's chi-squared test and its variations, is valid if the test statistic is chi-squared distributed under the null hypothesis. If there is a statistically significant difference between the expected frequencies and the observed frequencies in one or more categories of a contingency table, it can be determined using Pearson's chi-squared test. A Fisher's exact test is used as an alternative for contingency tables with smaller sample sizes.

The smallest positive integer that is neither prime nor square and that has no prime factor less than 50 is 3137.

This can be determined by using the prime factorization method. Prime factorization is a process of breaking down a number into its prime factors. The prime factors of a number are the factors that are only divisible by one and itself. For 3137, the prime factors are 3, 7, 17 and 37 since these are the only prime numbers that can divide 3137 evenly. Since none of the prime factors are less than 50, 3137 is the smallest positive integer that is neither prime nor square and that has no prime factor less than 50.

not sure

Step-by-step explanation:

"Every graph represents a function" - statement is false.

Correct option: D

The vertical line test is used to verify function. That is, a graph must have a unique y value for it to be referred to as a function for a certain (unique) value of x.

If for a particular x, and y values are coming it means it is not a function.

Hence, every graph is a function is false.

Because if it crosses y axis twice it means for a particular x value , two different value of y will exist. And that is not possible for a function

Hence option D is correct: The statement is false because a graph that crosses the y-axis two times does not represent a function.

Answer: x = -2

Step-by-step explanation:

The area bounded by the graphs of y and y0 over the given interval is A = ∫y0 dy|2-∫y0 dy|0.

The area bounded by the graphs of the indicated equations y and y0 over the given interval can be calculated using the formula A=∫y0 dy. To calculate the area, we need to first find the antiderivative of y0, which is F(y0) = ∫y0 dy. Then, we need to evaluate the integral from the lower limit of the given interval to the upper limit of the given interval. For example, if the given interval is from x=0 to x=2, then the area bounded by the two graphs would be A=F(y0)|2-0 = ∫y0 dy|2-0. Once we have evaluated the integral, we can calculate the area of the graph by subtracting the lower limit result from the antiderivative In this example, A=F(y0)|2-0 = ∫y0 dy|2-0 = F(y0)|2-F(y0)|0 = ∫y0 dy|2-∫y0 dy|0. Thus, the area bounded by the graphs of y and y0 over the given interval is A = ∫y0 dy|2-∫y0 dy|0.

Two sails are similar triangles.

So the angles of two sails are equal and the corresponding sides are proportional.

We can write the relation as,

x / 30 = x- 2 / 26 = y + 9 / 5y - 3

Consider x / 30 = x- 2 / 26.

Cross multiplying,

26x = 30(x - 2)

26x = 30x - 60

-4x = -60

x = 15

Consider x / 30 = y + 9 / 5y - 3.

Substituting x = 15,

15 / 30 = y + 9 / 5y - 3

1 / 2 = y + 9 / 5y - 3

Cross multiplying,

5y - 3 = 2y + 18

3y = 21

y = 7

Unknown sides are,

x = 15 feet

The equations are given below.

−12x + 9y = 7              ...1

The Typewriters should be guaranteed for 7.72 months, which would give a 5% chance of requiring a major repair before the end of the guarantee period.

Typewriter repair times have a normal distribution, with a mean of 11 months and a standard deviation of 2 months. To find the warranty period at which only her 5% of typewriters fail before the warranty expires, we need to find the corresponding z-score and solve it after the warranty period.

Using the standard normal distribution table, we find that the Z-score corresponding to a cumulative probability of 0.95 is approximately 1.64.

This means that 95% of typewriters will need major repairs after 11 + 1.64 * 2 = 14.28 months.

To ensure that only 5% of typewriters fail before the warranty expires, the warranty period should be set to 11 - 1.64 * 2 = 7.

72 months.

The average rate of change over the interval 15 ≤ x ≤ 30 is equal to -6/5.

In Mathematics, the average rate of change of f(x) on a closed interval [a, b] is given by this mathematical expression:

Average rate of change = [f(b) - f(a)]/(b - a)

Next, we would determine the average rate of change of the function f(x) over the interval [15, 30]:

a = 15; f(a) = 40

b = 30; f(b) = 22

For the average rate of change over the interval 15 ≤ x ≤ 30, we have the following:

Average rate of change = [f(b) - f(a)]/(b - a)

Average rate of change = [22 - 40]/(30 - 15)

Average rate of change = -18/15
