Step-by-step explanation:

Marlon can choose which 10 items to buy in 12397 ways.

Since Marlon wants to buy all 7 types of cheese, he needs to select 3 more items from the remaining 23 items (8 vegetables, 8 fruits, and 3 whole grain bread) to make a total of 10 items.

The formula for calculating the number of combinations is:

nCk = n! / (k! * (n-k)!)

By using the formula, we can calculate the number of ways.

The number of ways to select 3 items from 23 items is:

\($${23 \choose 3} = \frac{23!}{3!(23-3)!} = \frac{23 \times 22 \times 21}{3 \times 2 \times 1} = 1771$$\)

Therefore, Marlon can choose which 10 items to buy in 7 x 1771 = 12397 ways.

Step-by-step explanation:

-25 + 15 = -10

1 - 13 = -12

-1 divided by 5 = -1/5

-5 multiplied by -1/5 = 1

The bold ones are the answers

Answer:

Step-by-step explanation:

1) n+15=10

     solution;

n+15= -10

so, n= -10 -15

      n= -25

2) n-13= -12

        solution;

remember the rule i told you in number 1 that's the same rule we will use here

n= -12+ 13

n=1

you see so easy... lets continue

3) n\5= -1\5

now in this one there is a new rule which is; when you see two fractions and there is an equal two in between them you cross multiply... okay lets solve

n\5= -1\5

-1*5=n*5

the reason why i exchanged was because the unknown should always be at the left hand side....okay

n*5=-1*5

5n/5= -5/5

5 will divide 5 which is remaining n

5 divide 5 which is -1

so n = -1

4) -5n =1

 this is not a fraction so we just take the -5 to 1 and no cross multiplication (they are whole numbers so they meet each other)okay...

so, n=1/-5

The probability that the equipment will operate for at least 200 hours without failure is \((1-e^{-2} )^2[2e^-2+1]\).

Given:

mean = 1/100

Let X = the number of components that fail before 200 hours . The X has a binomial distribution n = 3 and p = 1 – e^-2.

probability p = 3/2\(p^{2} (1-p)\) + 3/3 \(p^{3}\).

= 3(\(1-e^-2)^2\)\(e^-2\) + (\(1-e^-2)^3\)

= \((1-e^-^2)^2[3e^-^2 - e^-^2+1]\)

= \((1-e^{-2} )^2[2e^-2+1]\)

Therefore the probability that the equipment will operate for at least 200 hours without failure is \((1-e^{-2} )^2[2e^-2+1]\).

The missing value for the letter b can be determined by finding the ratio of pencils to pens and applying it to the known value of pencils. The value of b is 168.

To find the missing value for the letter b, we need to determine the ratio of pencils to pens based on the given information. We can do this by dividing the number of pencils by the number of pens in each case.

In the first case, the ratio is 18/72 = 1/4.

In the second case, the ratio is 29/35 = 1/5.

To find the missing value for b, we need to apply the same ratio to the number of pens in the third case, which is 140.

Using the ratio 1/5, we can calculate b as follows:

b = (1/5) * 140 = 28.

However, there seems to be a mistake in the given answer choices. The correct value of b based on the calculations is 28, not 168. Therefore, the missing value for the letter b is 28.

Using mathematical operations, we know that Sofia will spend $56 and order 7 additional rolls of sushi (84 pieces).

An operation is a function in mathematics that transforms zero or more input values into a clearly defined output value.

The operation's arity is determined by the number of operands.

PEMDAS stands for Parentheses, Exponents, Multiplication, Division, and Addition Subtraction (from left to right).

So, they require at least 100 sushi pieces.

24 pieces of sushi had previously been ordered and paid for by Sofia.

Roll sushi is available.

Each roll = 12 pieces at $8

R = additional rolls that Sofia orders

Additional sushi = Needed sushi - ordered sushi

=100-24

=76 pieces of sushi

A roll contains 12 pieces.

76/12 = 6.33

Rolls must be ordered by Sofia.

She will therefore place 7 additional sushi rolls, each with 12 pieces.

12*7=84 pieces

Remember that they need at least 100 pieces, so there may be more than 100 in total.

84 pieces plus the 24 pieces Sofia has previously ordered.

The total number of pieces will be 108.

Therefore, using mathematical operations, we know that Sofia will spend $56 and order 7 additional rolls of sushi (84 pieces).

Among the given options, the "Success/Failure Condition" is not a requirement for testing means. The other three options—Randomization, Nearly Normal Condition, and 10% Condition—are necessary conditions to be considered when conducting hypothesis tests on means.

Randomization: Randomization is essential to ensure that the samples being compared are representative of the population and to minimize bias. Random assignment of individuals to treatment groups helps control for confounding variables and increases the validity of the statistical analysis.

Nearly Normal Condition: The Nearly Normal Condition assumes that the data follows a roughly normal distribution within each group being compared. This condition is important because many statistical tests, such as t-tests, rely on the assumption of normality to provide accurate results.

10% Condition: The 10% Condition is relevant when sampling from a finite population. It states that the sample size should be no more than 10% of the population size to ensure that the sampling process does not significantly affect the population distribution.

Success/Failure Condition: The Success/Failure Condition is not directly related to testing means. It is typically associated with tests involving proportions, where the condition specifies that both the number of successes and the number of failures should be at least 10 in each sample or category being compared.

7 Kids like cats

Step-by-step explanation:

The null hypothesis is accepted since the chi-square at the supplied critical value level value is greater than 13.388 (27.385).

In five to six key stages, the hypothesis test announces the conclusion of an assumption.

The approach to be utilized is predicated on the notion of correlating a parameter's standardized sample equivalent to the crucial boundary that permits the null hypothesis to be accepted.

For this particular question,

The value of the chi-square is 27. 385.

The crucial number is 13.388.

The following are the hypotheses for the goodness of fit test : If an expected value and the observed values are identical, the value is considered null. Alternative: The expected value and the observed values differ substantially. One tail exists in the chi-square test.

The standard is as follows:

If the test statistic is higher than the threshold value, the null hypothesis is rejected. The same null hypothesis is rejected if the test statistic is below the crucial value. Because the chi-square is greater than 13.388 and the critical value is provided, the null hypothesis is therefore accepted at that level.

The mean, variance, and standard deviation of the distribution is 20.74, 1.3210, and 1.1493, respectively.

First, the mean can be found using the following formula:

Mean = ∑x(p(x))

Mean = (19)(0.22) + (20)(0.20) + (21)(0.32) + (22)(0.14) + (23)(0.12)

Mean = 4.18 + 4 + 6.72 + 3.08 + 2.76

Mean = 20.74


Next, the variance can be found using the following formula:

Variance = ∑(x-mean)²(p(x))

Variance = (19-20.74)²(0.22) + (20-20.74)²(0.20) + (21-20.74)²(0.32) + (22-20.74)²(0.14) + (23-20.74)²(0.12)

Variance = 0.5362 + 0.0552 + 0.0173 + 0.1754 + 0.5369

Variance = 1.3210


Finally, the standard deviation can be found using the following formulas:

Standard deviation = √variance

Standard deviation = √1.3210

Standard deviation = 1.1493


So, the mean is 20.74, the variance is 1.3210, and the standard deviation is 1.1493, all rounded to 4 decimal places.

The least-square equation for the given (x,y) data pairs is: y = 0.9048x + 0.6190

To find the least-square equation for the given (x,y) data pairs, we can use the method of linear regression. The equation of a line is given by:

y = mx + b

where m is the slope of the line and b is the y-intercept. The values of m and b can be calculated using the following formulas:

m = (nΣ(xy) - ΣxΣy) / (nΣ(x^2) - (Σx)^2)

b = (Σy - mΣx) / n

where n is the number of data points.

Using the given data, we can calculate the values of Σx, Σy, Σxy, and Σ(x^2) as follows:

Σx = 2 + 1 + 5 = 8

Σy = 4 + 3 + 8 = 15

Σxy = (24) + (13) + (5*8) = 42

Σ(x^2) = (2^2) + (1^2) + (5^2) = 30

Substituting these values into the formulas for m and b, we get:

m = ((342) - (815)) / ((330) - (8^2)) ≈ 0.9048

b = (15 - (0.90488)) / 3 ≈ 0.6190

Therefore, the least-square equation for the given data is:

y = 0.9048x + 0.6190

Rounded to four digits after the decimal, the equation becomes:

y = 0.9048x + 0.6190
