Mr . Lopez made 339 ounces of strawberry jam . He plans to divide the jam equally among his 12 cousins. How many ounces of jam will each cousin get?

The numerator degree of freedom for the F test statistic to determine if the factor bread was significant would be 3.

This is because there are 4 different kinds of bread, but when conducting a two-way ANOVA test, one of the groups is always used as the reference group. Therefore, there are only 3 groups of bread that are being compared to each other. The denominator degree of freedom would be 56 (60 total samples minus 4 groups of bread and 5 groups of meat).

The F test statistic would determine if there is a significant difference in revenues between the different kinds of bread, while also controlling for the effect of the different kinds of meat.

The probability that the sample mean of 46 racing cars would be greater than 116.9 gallons is 0.0043, or 0.43%.

To solve this problem, we can use the central limit theorem, which states that the sampling distribution of the sample means approaches a normal distribution as the sample size increases.
First, we need to calculate the standard error of the mean, which is the standard deviation of the population divided by the square root of the sample size:
standard error = 7 / sqrt(46) = 1.032
Next, we can standardize the sample mean using the formula:
z = (sample mean - population mean) / standard error
In this case, the population mean is 114 and the sample mean we're interested in is 116.9. So:
z = (116.9 - 114) / 1.032 = 2.662
Finally, we can use a standard normal distribution table or calculator to find the probability that a z-score is greater than 2.662. This probability is approximately 0.0043, rounded to four decimal places.
Therefore, the probability that the sample mean of 46 racing cars would be greater than 116.9 gallons is 0.0043, or 0.43%.

Answer:

D

Step-by-step explanation:

The last option.

The roots of the quadratic equation 0 = 2x² + 12x-14 is (C) x=-7 and x=1.

Any equation in algebra that can be written in the standard form where x stands for an unknown value and a, b, and c stand for known values is said to be a quadratic equation.

In general, it is assumed that a > 0; equations with a = 0 are regarded as degenerate since they become linear or even simpler.

So, the roots of 0 = 2x² + 12x-14 are:

2x² + 12x-14  = 0

2x² + 14x - 2x -14

2x(x + 7) - 2(x + 7)

(2x - 2) (x + 7)

Now, use the zero product property as follows:

2x - 2 = 0

2x = 2

x = 2/2

x = 1

And

x + 7 = 0

x = -7

Therefore, the roots of the quadratic equation 0 = 2x² + 12x-14 is (C) x = -7 and x = 1.

Answer:

8km  5mi

Step-by-step explanation:

20x400=8000meters a km = to 1000meters

8000/1000=8km

A mile is a kilometer/ 1.6  8/1.6=5 miles

Sanford ran approximately 8 kilometers and about 4.97 miles.

Given that a coach made someone run 20 laps on a 400 m track.

We need to find the number of mile he ran as well as number of kilometers he ran.

To find out how many kilometers Sanford ran, we can use the fact that 1 kilometer is equal to 1000 meters.

Similarly, to find out how many miles he ran, we'll use the conversion factor of 1 mile being equal to approximately 1609.34 meters.

Let's calculate it:

1 lap = 400 meters

20 laps = 20 x 400 = 8000 meters

Kilometers:

8000 meters ÷ 1000 meters/kilometer = 8 kilometers

Miles:

8000 meters ÷ 1609.34 meters/mile ≈ 4.97 miles

So, Sanford ran approximately 8 kilometers and about 4.97 miles.

Answer:

$6,191.66

Step-by-step explanation:

We can use the formula for compound interest to solve this problem:

A = P(1 + r/n)^(nt)

where:

A = the amount owed after 5 years

P = the initial loan amount = $2000

r = the annual interest rate expressed as a decimal = 0.20

n = the number of times the interest is compounded per year = 2 (semiannually)

t = the number of years the loan is outstanding = 5

Plugging in these values, we get:

A = 2000(1 + 0.20/2)^(2*5)

= 2000(1.10)^10

≈ $6,191.66

Therefore, the amount owed after 5 years is approximately $6,191.66.

The order of the group generated by matrices a and b under matrix multiplication is a process of multiplying the matrices and counting the number of distinct matrices that can be produced.

A matrix is a rectangular array of numbers, symbols, or expressions, arranged in rows and columns.

The order of a group generated by matrices a and b refers to the number of distinct matrices that can be produced by multiplying a and b a certain number of times.

To find the order of the group, we need to start by multiplying a and b and see if we get any new matrices. If we do, we keep multiplying those matrices until we get back to the original matrices a and b.

The order of the group is the number of distinct matrices we get in this process.

It is important to note that matrix multiplication is associative, which means that the order in which we multiply the matrices does not affect the result. Also, the identity matrix is a special matrix that, when multiplied by any matrix, produces the same matrix.

The equation for the plane tangent to the surface z = x’y + xy² + Inx+R at (1,0, R) is is: z - R = x - 1 + y

To find the equation of the tangent plane to the surface z = x'y + xy² + ln(x) + R at the point (1,0,R), we need to first compute the partial derivatives of the function with respect to x and y, which represent the slopes of the tangent plane in the x and y directions.

The partial derivative with respect to x is: ∂z/∂x = y² + y' + 1/x The partial derivative with respect to y is: ∂z/∂y = x² + x' Now, we evaluate the partial derivatives at the given point (1,0,R): ∂z/∂x(1,0) = 0² + 0 + 1 = 1 ∂z/∂y(1,0) = 1² + 0 = 1

The tangent plane's equation can be given by: z - R = (1)(x - 1) + (1)(y - 0) Thus, the equation of the tangent plane is: z - R = x - 1 + y

(a)The probability that the selected individual owns shares in the balanced fund is 8%, that is 0.08.

(b)The probability that the selected individual owns shares in a bond fund is 26%.

(c)The probability that the selected individual does not own shares in a stock fund is 57%.

(a) A probability is a number that indicates how likely an event is to occur. In this case, the event is the selected individual owning shares in the balanced fund. The percentage of customers who own shares in the balanced fund is given as 8%. This means that if 100 customers own shares in just one fund, 8 of them would own shares in the balanced fund.

(b) To find the probability that the individual owns shares in a bond fund, we need to add up the percentages of customers who own shares in each of the bond funds:

Short bond: 14%

Intermediate bond: 7%

Long bond: 5%

Total bond funds: 14% + 7% + 5% = 26%

So, the probability that the selected individual owns shares in a bond fund is 26%.

(c) To find the probability that the selected individual does not own shares in a stock fund, we need to find the complement of the probability that the individual owns shares in a stock fund. The probability that the individual owns shares in a stock fund is the sum of the percentages of customers who own shares in each of the stock funds:

Moderate-risk stock: 25%

High-risk stock: 18%

Total stock funds: 25% + 18% = 43%

So, the probability that the selected individual does not own shares in a stock fund is 1 - 43% = 57%.

uploading the picture is an excellent way to make sure we get the original problem definition.

but I just answered this (even without the picture). so, you need it again ?

The main answer is: y = -12x - 8. To find the equation that represents the same relationship as the table, we need to first calculate the slope of the line. We can do this by choosing two points from the table and using the slope formula:

slope = (y2 - y1) / (x2 - x1)

Let's choose the first and last points (-20, -268) and (1, -40):

slope = (-40 - (-268)) / (1 - (-20))
slope = 228 / 21

Now that we have the slope, we can use the point-slope form of a linear equation to write the equation:

y - y1 = m(x - x1)

Using the first point (-20, -268) and the slope we just calculated, we get:

y - (-268) = (228 / 21)(x - (-20))

Simplifying, we get:

y = (228 / 21)x - 440 / 21 - 268

y = (228 / 21)x - 532 / 21

This is the equation that represents the same relationship as the table. However, it's not in the standard form y = mx + b, so we can simplify it further:

y = (228 / 21)x - 532 / 21
y = (12 / 7)x - 8

This is the same as:

y = -12x/7 - 8/1

So the final answer is:

y = -12x - 8

The algebraic equation "0.40x = 400" represents the words: forty percent of Mrs. Garcia's score is 400 points. Mrs. Garcia's score is 1000.

Algebraic equation is an equation made up of variables and coefficients that can be used to solve mathematical problems or questions.

To formulate an algebraic equation, we designate a variable for unknown values.

Mrs. Garcia's score is unknown, and so

let x = Mrs. Garcia's score

Based on the information given on the problem, forty percent of Mrs. Garcia's score is 400 points. Forty percent can be written as 0.40.

40% of x is 400

0.40x = 400

Hence, the algebraic equation for that is 0.40x = 400.

Evaluating the value of x,

0.40x = 400

x = 400 / 0.40

x = 1000

Therefore, Mrs. Garcia's score is 1000.

Step-by-step explanation:

You can solve it by various methods. These two equations can be solved simultaneously or by matrix method, or even by graphing

Simultaneous is easier so lets get started.

1st equation  : \(-2x+y=8\)

2nd equation: \(-3x-y=7\)

We solve it by using the substitution method which means there are two variables x and y and we substitute one variable in form of another variable.

Like, take the 1st equation

\(-2x+y=8\\y=8+2x\)

the equation is arranged in a different manner but its the same thing.

This new equation becomes our new third equation and now we simply put our third equation in our 2nd equation. Like this, take the 2nd equation and substitute it with our 3rd third equation

\(-3x-y=7\\-3x-7=y\\-3x-7=8+2x\\-3x-2x=8+7\\-5x=15\\x=-3\)

we get x=-3 and then we put the value of x and in our third equation to get the value of y or we can simply put it in any equation 1st , 2nd , 3rd it will give the same answer. I chose third.
