Answer:

36 ounces

Step-by-step explanation:

We want to find the total amount of gravy the restaurant will need.

Multiply the gravy needed for one serving by the number of servings.

gravy for one serving × number of servings.

The restaurant uses 4/5 of an ounce for each serving, and 45 people ordered meatloaf. Therefore, the gravy for one serving is 4/5, and the number of servings is 45.

4/5 × 45

45 is equivalent to 45/1.

4/5 ×  45/1

Multiply across the numerator (the top numbers: 4 and 45) and denominator (the bottoms numbers: 5 and 1)

(4× 45)/(5× 1)

180/5

Divide

36

Add appropriate units. In this case, the units are ounces.

36 ounces

The restaurant needs 36 ounces of gravy for 45 servings of meatloaf.

Answer:

22cm

See explanation below

Step by step explanation:

The question is incomplete without the diagram of the shape or its dimensions.

From the question, we are to determine the perimeter of the circle.

Let's consider the following question by determining the perimeter of a circle. If diameter is 7cm. Use pi as 3.14.

Perimeter of circle = circumference of circle

circumference of circle = 2πr

Radius = diameter/2 = (7/2)cm

circumference of circle = 2πr

= 2×π×(7/2) = (14/2)×3.14

= 7×3.14

=21.98cm

circumference of circle = 22cm (nearest tenth)

Perimeter of circle = 22cm

Answer:

Width (x) = 160ft

See explanation below

Step-by-step explanation:

The information given is incomplete as we are not told if the shape of the pond. This is about determining the surface area of a water body.

Looking at the question, we can tell we are to find the width of a pond whose shape wasn't given.

Assuming the shape of the pond is either a rectangular or square pond, let's consider the following question:

The acreage of a rectangular pond is 1.54 acres and the length is 420ft. The width of the pond shown is x ft. What is the value of x.

Find attached the diagram used for solving the question.

Formula for calculating the acreage of

a Square or Rectangular Ponds is multiplying average length (in feet) times average width (in feet) and dividing the result by 43,560 to derive our answer in acres.

That is: Average Length (ft) × Average Width (ft) ÷ 43,560 = Acres

Since we have been given acreage and length, we would make width subject of formula.

Width = (Acreage × 43500)/length

Width (x) = (1.54 × 43,560)/420

=67082.4 ÷ 420 = 159.72

Width (x) = 160ft (nearest feet)

Answer:

x = 3

area = 6

Step-by-step explanation:

using phytagoras's. theorem

a² + b² = c² (with c is the longest one)

x² + (x+1)² = 5²

x² + x² + 2x + 1 = 25

2x² + 2x - 24 = 0 (divide all by 2)

x² + x -12 = 0 then factorize

(x-3)(x+4) = 0

we get x = 3 and x = -4. Take the positive one.

so now we have x = 3 then x + 1 must be 4.

the area is

Step-by-step explanation:

The formula for the volume of a cylinder:

V = πr²h

Let's substitute into the given equation:

V = πr²h

V = (3.14)(8²)(10)

Solve:

V = (3.14)(8²)(10)

V = (3.14)(64)(10)

V = (200.96)(10)

V = 2,009.6

Therefore, the volume of the cylinder is 2,009.6 cubic inches.

Answer:

[tex]Salary = Rs23000[/tex]

Step-by-step explanation:

Given

[tex]Shopping = \frac{1}{5}[/tex]

[tex]Sister = \frac{2}{5}R[/tex]

[tex]Left over = Rs11,040[/tex]

Required

Her salary in that month

Given that she spent [tex]\frac{1}{5}[/tex] of her salary on shopping, this implies that she has [tex]\frac{4}{5}[/tex] of her salary left

From what's left, she gave her sister [tex]\frac{2}{5}[/tex]

This means she gave her sister [tex]\frac{2}{5} * \frac{4}{5}[/tex]

Sister = [tex]\frac{8}{25}[/tex]

Calculating a fraction of what's left

[tex]Left over = 1 -Shopping - Sister[/tex]

[tex]Left over = 1 - \frac{1}{5}- \frac{8}{25}[/tex]

[tex]Left over = \frac{25 - 5 - 8}{25}[/tex]

[tex]Left over = \frac{12}{25}[/tex]

Recall that she has Rs11,040

This means that

[tex]\frac{12}{25} of Salary = Rs11,040[/tex]

Multiply both sides by [tex]\frac{25}{12}[/tex]

[tex]\frac{12}{25} * \frac{25}{12} * Salary = Rs11,040 * \frac{25}{12}[/tex]

[tex]Salary = Rs11,040 * \frac{25}{12}[/tex]

[tex]Salary = \frac{Rs276000}{12}[/tex]

[tex]Salary = Rs23000[/tex]

Hence, her salary for that month was Rs23000

Answer:

Her salary = Rs 23000

Step-by-step explanation:

In a month, Ezhil spent 1/5 of her salary on shopping.

Let

Her salary = a

she spent 1/5 of a on shopping

Amount spent on shopping = 1a/5

She gave 2/5 of the remaining to her sister .

The remaining money = a - 1a/5 = 5a - a/5 = 4a/5

She gave 2/5 of 4a/5 to her sister. Therefore,

The amount she gave to her sister = 2/5 × 4a/5 = 8a/25

Out of her salary she is left with Rs 11040 .Therefore,

a - 1a/5 - 8a/25 = 11040

25a - 5a - 8a/25 = 11040

12a/25 = 11040

12a = 11040 × 25

12a = 276000

divide both sides by 12

a = 276000/12

a = 23000

Her salary = Rs 23000

Answer:

Yes. There is enough evidence to support the claim that the proportion of individuals who caught pertussis and were not up to date on their booster shot is higher than those that were.

P-value = 0.00013.

Step-by-step explanation:

This is a hypothesis test for the difference between proportions.

The claim is that the proportion of individuals who caught pertussis and were not up to date on their booster shot is higher than those that were.

Then, the null and alternative hypothesis are:

[tex]H_0: \pi_1-\pi_2=0\\\\H_a:\pi_1-\pi_2> 0[/tex]

The significance level is 0.05.

The sample 1 (Group 1), of size n1=145 has a proportion of p1=0.124.

[tex]p_1=X_1/n_1=18/145=0.124[/tex]

The sample 2 (Group 2), of size n2=355 has a proportion of p2=0.037.

[tex]p_2=X_2/n_2=13/355=0.037[/tex]

The difference between proportions is (p1-p2)=0.088.

[tex]p_d=p_1-p_2=0.124-0.037=0.088[/tex]

The pooled proportion, needed to calculate the standard error, is:

[tex]p=\dfrac{X_1+X_2}{n_1+n_2}=\dfrac{18+13.135}{145+355}=\dfrac{31}{500}=0.062[/tex]

The estimated standard error of the difference between means is computed using the formula:

[tex]s_{p1-p2}=\sqrt{\dfrac{p(1-p)}{n_1}+\dfrac{p(1-p)}{n_2}}=\sqrt{\dfrac{0.062*0.938}{145}+\dfrac{0.062*0.938}{355}}\\\\\\s_{p1-p2}=\sqrt{0+0}=\sqrt{0.001}=0.024[/tex]

Then, we can calculate the z-statistic as:

[tex]z=\dfrac{p_d-(\pi_1-\pi_2)}{s_{p1-p2}}=\dfrac{0.088-0}{0.024}=\dfrac{0.088}{0.024}=3.68[/tex]

This test is a right-tailed test, so the P-value for this test is calculated as (using a z-table):

[tex]\text{P-value}=P(z>3.68)=0.00013[/tex]

As the P-value (0.00013) is smaller than the significance level (0.05), the effect is significant.

The null hypothesis is rejected.

There is enough evidence to support the claim that the proportion of individuals who caught pertussis and were not up to date on their booster shot is higher than those that were.

Answer:

Step-by-step explanation:

  This particular permutation  deals with words that have repeated letters.

Given word = "ONGOING"

the formula for the permutation is

[tex]= \frac{n!}{mA! mB!.....mZ!}[/tex]

where   n   is the amount of letters in the word, and  m A , m B , ... , m Z  are the occurrences of repeated letters in the word. Each   m  equals the amount of times the letter appears in the word.

So in the word  "ONGOING"

n= 7

mO= 2

mN= 2

mG=2

[tex]permutations = \frac{7!}{2!2!2!} \\\\permutations= \frac{7*6*5*4*3*2*1}{(2*1)*(2*1)*(2*1)}[/tex]

[tex]permutations= \frac{52920}{8} \\permutation = 6,615[/tex]

Answer:

Step-by-step explanation:

a) Confidence interval for the difference in the two proportions is written as

Difference in sample proportions ± margin of error

Sample proportion, p= x/n

Where x = number of success

n = number of samples

For the girls,

x = 60

n1 = 80

p1 = 60/80 = 0.75

For the boys

x = 80

n2 = 120

p2 = 80/120 = 0.67

Margin of error = z√[p1(1 - p1)/n1 + p2(1 - p2)/n2]

To determine the z score, we subtract the confidence level from 100% to get α

α = 1 - 0.8 = 0.2

α/2 = 0.2/2 = 0.1

This is the area in each tail. Since we want the area in the middle, it becomes

1 - 0.1 = 0.9

The z score corresponding to the area on the z table is 1.282. Thus, z score for confidence level of 80% is 1.282

Margin of error = 1.282 × √[0.75(1 - 0.75)/80 + 0.67(1 - 0.67)/120]

= 1.282 × √0.00418625

= 0.081

Confidence interval = 0.75 - 0.67 ± 0.081

= 0.08 ± 0.081

b) The formula for determining the standard error of the distribution of differences in sample proportions is expressed as

Standard error = √{(p1 - p2)/[(p1(1 - p1)/n1) + p2(1 - p2)/n2}

Therefore,

Standard error = √{(0.

75 - 0.67)/[0.75(1 - 0.75)/80 + 0.67(1 - 0.67)/120]

Standard error = √0.08/0.00418625

Standard error = 4.37

c) the difference in the probability between that girls prefer math more and boys prefer math more is

0.75 - 0.67 = 0.08

Answer:

This line can be represented by the line y = 3/4x + 2.

Step-by-step explanation:

The slope is identified as the m in y = mx + b. The slope is the rise/run of your line (AKA how many units it goes upwards/downwards and then goes to the right/left to meet the second given point).

In this case, the line rises 3 units from 2 to 5, and then goes to the right by 4 units to meet the coordinate (4, 5).

B in the equation refers to the y-intercept, or where the line intersects/crosses the y-axis. In this case, it is the coordinate (0, 2).

Finally, x is irrelevant and is placed in the equation for no reason (at least that I am aware of in my several years of high school math).

Therefore, your final equation is y = 3/4x + 2.
