Answer:

He needs to sell 157 sandwiches to earn $125

Step-by-step explanation:

●$10.50×6 hrs= $63

●$125 - $63= $62 {So he needs to sell $62 worth of sandwiches}

●$0.40 × 157= $62

pov:《$62 + $63 = $125》

Answer:

155 sandwiches

Step-by-step explanation:

First we see what the base rate is for his six-hour shift. We do this by multiplying 10.50 by 6 which is 63. Then we do 125-63 which is 62. As he gets 42 cents per sandwich so we do 62÷0.40, which equals 155 so he needs to sell 155 sandwiches.

The curvature of the curve is 55/9 in accordance with the provided declaration.

Curve, An abstract phrase used to express the trajectory of a steadily moving particle in mathematics (see continuity). Usually, an equation will create such a route. The term may also be used to describe a linear model or a collection of connected line segments. The IS curve displays variants of interest rates plus production levels where anticipated expenditure and income are equal. The many interest and income configurations along whom the merchandise is in homeostasis are represented by the IS Curve.

[tex]\mathbf{r}(t)=\left\langle 6 t, t^2, \frac{1}{9}\left(t^3\right)\right\rangle[/tex]

So,

Now calculating length of the given curve from 0 to 1,

[tex]\begin{aligned}& L=\int_0^1 \sqrt{(6)^2+(2 t)^2+\left(\frac{1}{3}\left(t^2\right)\right)^2} d t \\& =\int_0^1 \sqrt{(6)^2+2 \cdot 6 \cdot \frac{1}{3}\left(t^2\right)+\left(\frac{1}{3}\left(t^2\right)\right)^2} d t \\& =\int_0^1 \sqrt{\left(6+\frac{1}{3}\left(t^2\right)\right)^2} d t\end{aligned}[/tex]

[tex]\begin{aligned}& =\int_0^1\left(6+\frac{1}{3}\left(t^2\right)\right) d t \\& =\int_0^1 6 d t+\int_0^1 \frac{1}{3}\left(t^2\right) d t \\& =6 \int_0^1 d t+\frac{1}{3} \int_0^1 t^2 d t \\& =6[t]_0^1+\frac{1}{3}\left[\frac{t^{2+1}}{2+1}\right]_0^1 \\& =6[1-0]+\frac{1}{3}\left[\frac{t^3}{3}\right]_0^1\end{aligned}[/tex]

[tex]\begin{aligned}& =6(1)+\frac{1}{3}\left[\frac{1^3}{3}-\frac{0^3}{3}\right] \\& =6+\frac{1}{3}\left[\frac{1}{3}-0\right] \\& =6+\frac{1}{9} \\& =\frac{54+1}{9}\end{aligned}[/tex]

The proportion of people in the area who would purchase food from the restaurant is greater than 60%.

Hypothesis testing is used to determine if the proportion of people in a particular area that would purchase food from a particular restaurant is greater than 60%. The null hypothesis, denoted by H0, is that the proportion of people who would purchase food from the restaurant is 60%, or p=0.6. The alternative hypothesis, denoted by H1, is that the proportion of people who would purchase food from the restaurant is greater than 60%, or p>0.6.

To conduct the test, we can use a one-sample proportion test, which is a type of statistical test that compares an observed proportion to a hypothesized proportion. To calculate the test statistic, we can use the formula:

Test statistic = (observed proportion - hypothesized proportion) / (standard error of the proportion)

In this case, the observed proportion is 320/500 = 0.64 and the hypothesized proportion is 0.6. Therefore, the test statistic is:

Test statistic = (0.64 - 0.6) / (square root of (0.6 * (1 - 0.6) / 500))

Test statistic = 0.04 / (square root of (0.6 * 0.4 / 500))

Test statistic = 0.04 / 0.0341

Test statistic = 1.17

The test statistic is 1.17, which is greater than the critical value of 1.645. Therefore, we can reject the null hypothesis and conclude that the proportion of people in the area who would purchase food from the restaurant is greater than 60%.

Answer: 53

Step-by-step explanation:

If 9 ≤ 3/4 + x,

x ≥ 8 1/4 (Transpose the 3/4)

So, the least possible value of 8x - 13 will be when x is the least or, x is 8 1/4

or 33/4

8 x 33/4 - 13 = 66 - 13 = 53

Answer:

I hope my answer is correct!

The least possible value of 8x-13 when 9 <= 3/4 +x is -13. This is because when x = 9, 8x-13 = 8(9)-13 = 72-13 = 59, which is the least possible value of 8x-13 when 9 <= 3/4 +x.

The range of the function is given by set A = { -11 , -9 , -7 , -5 , -3 }

The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.

The range is the set of outputs of a relation or function. In other words, it's the set of possible y values. Recall that ordered pairs are of the form (x,y) so the y coordinate is listed after the x. The output is listed after the input.

Given data ,

Now , the function is given by

f ( x ) = 2x - 7   be equation (1)

Let the domain of the function be represented as set B = { -2 , -1 , 0 , 1 , 2 }

Substitute the value for x in the given equation , we get

when x = -2

f ( x ) = 2x - 7

f ( -2 ) = 2 ( -2 ) - 7

f ( -2 ) = -4 - 7 = -11

when x = -1

f ( x ) = 2x - 7

f ( -1 ) = 2 ( -1 ) - 7

f ( -1 ) = -2 - 7 = -9

when x = 0

f ( x ) = 2x - 7

f ( 0 ) = 2 ( 0 ) - 7

f ( 0 ) = 0 - 7 = -7

when x = 1

f ( x ) = 2x - 7

f ( 1 ) = 2 ( 1 ) - 7

f ( 1 ) = 2 - 7 = -5

when x = -2

f ( x ) = 2x - 7

f ( 2 ) = 2 ( 2 ) - 7

f ( 2 ) = 4 - 7 = -3

Answer:

We can set up two equations to represent the information given in the problem:

F = 2S (where F is the father's present age and S is the son's present age)

(F - 10) / (S - 10) = 5/2

We can substitute equation 1 into equation 2:

(2S - 10) / (S - 10) = 5/2

We can cross-multiply and simplify to solve for S:

2S - 10 = 5S - 25

3S = 35

S = 35/3

S = 11.67

So the son is currently 11.67 years old. To find the father's age, we can use equation 1:

F = 2S

F = 2 * 11.67

F = 23.33

So the father is currently 23.33 years old.

The equation and the accompanying justification that describes a line that is parallel to EF is: C. Y = -1/3x + 5 1/3 the slopes are equal.

If two lines are said to be parallel to each other, their equations that is expressed as y = mx + b, will have the same slope value of m. Y = mx + b is the slope-intercept form of any equation that represents a line.

Given that the equation y = -1/3x + 4 represents the line EF, its slope is -1/3. This means the slope of any line that is parallel to y = -1/3x + 4 will be the same as -1/3.

Assuming that the company’s claims are true, there is a probability of 0.9824 that the first person to have a college degree is the third person selected at random.

The company claims that 74% of its employees hold college degrees.

Taking the total number of employees as 1,

The probability of employees who do hold a college degree P(3) is 0.74

Therefore, the probability of employees who do not have a college degree is (1-0.74) = 0.26

The probability that the first 2 employees do not have a college degree P(1&2) is 0.26^2

The equation thus turns out to be;

Probability that the 3rd person is the first to hold a college degree = P(1&2)*P(3)= (0.26^2)*0.74= 0.9824

The statement that the mean is most likely to be affected by an outlier, is True.

The mean (average) of a set of data can be significantly affected by outliers, or data points that are much higher or lower than the majority of the data. Outliers can greatly influence the mean, pulling it away from the center of the data and making it less representative of the majority of the data.

This can cause the mean to become skewed and can give a false representation of the typical values in the data set.

Answer:

Step-by-step explanation:

If everyone picks zero, they all win. Only Nash equilibrium is when everyone guesses zero or an extremely low number.

There is no purely dominant tactic in this game. There is a special pure strategy Nash equilibrium, though. Through the iterative elimination of weakly dominated techniques, this equilibrium can be discovered.

Since it cannot potentially be 2/3rds of the average of any guess, guessing any number that lies above 66.67 is dominated for every player. These might be taken away.

Any estimate above 44.45 is weakly dominated for every player once these techniques are removed for each player since no player would guess above 66.67 and 2/3 of 66.67 is roughly 44.45. This procedure will keep going until all numbers higher than 0 are gone.
