Answer:

  60

Step-by-step explanation:

Gavin has 20/4 = 5 times as many sweets as his corresponding number of ratio units. The total number of ratio units is 4+5+3 = 12, so the total number of sweets is 5×12 = 60.

There are 60 sweets altogether.

Answer:

1/4 of however many cups of onions she starts with

Step-by-step explanation:

I see no attachment and it doesn't say in your question how many onions she has. All you have to do is take the total amount of onions and divide it by 4 since she is splitting her total into 4 pots.

Step-by-step explanation:

Step-by-step explanation:

How to Find the Mean

Add up all data values to get the sum

Count the number of values in your data set

Divide the sum by the count

The mean is the same as the average value in a data set.

Mean Formula

The mean x of a data set is the sum of all the data divided by the count n.

Answer:

The pvalue of the test is 0.3844 > 0.1, which means that there is not sufficient evidence at the 0.10 level to support the executive's claim

Step-by-step explanation:

A publisher reports that 35% of their readers own a laptop.

This means that the null hypothesis is:

[tex]H_0: p = 0.35[/tex]

A marketing executive wants to test the claim that the percentage is actually different from the reported percentage.

This means that the alternate hypothesis is:

[tex]H_{a}: p \neq 0.35[/tex]

The test statistic is:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.

0.35 is tested at the null hypothesis:

This means that [tex]\mu = 0.35, \sigma = \sqrt{0.35*0.65}[/tex]

A random sample of 190 found that 32% of the readers owned a laptop.

This means that [tex]X = 0.32, n = 190[/tex]

Z-statistic:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{0.32 - 0.35}{\frac{\sqrt{0.35*0.65}}{\sqrt{190}}}[/tex]

[tex]z = -0.87[/tex]

pvalue of the test and decision:

As we are testing that the mean is different from a value and z is negative, the pvalue of the test is 2 multiplied by the pvalue of z = -0.87

Looking at the z-table, z = -0.87 has a pvalue of 0.1922

2*0.1922 = 0.3844

0.3844 > 0.1, which means that there is not sufficient evidence at the 0.10 level to support the executive's claim

The answer should be somewhere near 6* 2 = 12 which is the first answer. Do not put an exact answer when you are asked for an estimate.

The exact answer is 6.48 * 1.8 = 11.664 which makes 12 look like a pretty good estimate.

Answer:

Step-by-step explanation:

The average is 81 a low B, but if you throw out the low score it rises to 88.8, a high B.

I would use the median 88, 89 since it is higher and is a more accurate representation of the majority of the class

A) Yes, we can say that the class did well.

B)I would choose median to describe the data.

How to find mean, median and mode?

Mean simply means average of the data given, Here,

[tex]Mean=\dfrac{89+87+93+90+12+91+88+87+83+91}{10} =80.9[/tex]

Median is the value of data set (when arranged in ascending order) that divides it into two sets and is often called the middle number. When no. pf values in data set is even, the median is N/2.

Here,

[tex]Median=\dfrac{10}{2} ^{th}=5^{th} term=88[/tex]   (data taken in ascending order)

Mode is the value which has largest frequency among the all the other values.

Here, Mode is 87 and 91.

A) The class did well if we consider the data from point of view of its median and mode, but the average value is a bit low as we have a drastically low value that is 12.

B) I would describe the data by median because the class mean is very low and as there are 2 mode values, it is not the best representation of the score. The median of the set is a high and singleton value, therefore the most accurate measure of central tendency would be median.

Answer:

Step-by-step explanation:

The zeroes are the values of such that

m² - 11m + 18 = 0

Quadratic formula:

m = [11 ± √(11² - 4∘1∘18)]/[2∘1]

= [11 ± √49]/2

= [11 ± 7]/2

Answer: [tex]2+i5,\ 29[/tex]

Step-by-step explanation:

Given

Complex number is [tex]2-i5[/tex]

Its conjugate is obtained by changing the sign of the original number i.e. [tex]2+i5[/tex]

The product of the two numbers is

[tex]\Rightarrow (2-i5)(2+i5)=2^2-(5i)^2\quad \quad [(x+y)(x-y)=x^2-y^2]\\\\\Rightarrow (2-i5)(2+i5)=4-25i^2\\\\\Rightarrow (2-i5)(2+i5)=4+25=29[/tex]

Answer:

Colleen alone to clear the yard of leaves in 40 minutes

Step-by-step explanation:

P.S - The exact question is -

Given - Seas and Colleen are raking leaves in their yard. Working together they can clear the yard of leaves in 24 minutes. What kind of long it would take Sean 20 minutes longer to clear the yard dinner with Colleen working alone

To find - When c is the number of minutes it would take Colleen to finish the job when working alone, the situation is modeled by this rational equation: How long would it take Colleen alone to clear the yard of leaves?

Proof -

Given that the equation is -

[tex]\frac{1}{c} + \frac{1}{c+20} = \frac{1}{24} \\\frac{c + 20 + c}{c(c+20)} = \frac{1}{24}\\\frac{2c + 20}{c^{2} +20c} = \frac{1}{24}\\24(2c + 20) = c^{2} +20c\\48c + 480 = c^{2} +20c\\28c + 480 = c^{2}\\c^{2} - 28c - 480 = 0\\c^{2} - 40c + 12c - 480 = 0\\c(c - 40) + 12(c - 40) = 0\\(c+12)(c-40) = 0\\c = -12, 40[/tex]

As time can not be negative

So,

we get

c = 40 minutes

∴ we get

Colleen alone to clear the yard of leaves in 40 minutes
