There are 9/10 groups of Two-thirds are in Three-fifths.

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

There are groups of Two-thirds are in Three-fifths.

Now,

Let x groups of Two-thirds are in Three-fifths.

Hence, we can formulate;

⇒ x = 3/5 ÷ 2/3

⇒ x = 3/5 × 3/2

⇒ x = 9/10

Thus, Number of groups of Two-thirds are in Three-fifths = 9/10

We can see here that the total weight of candy in a 5/6 pound bag site is 377 grams.

Weight is a measure of the force exerted by gravity on an object. It is the measure of how heavy an object is. Weight is typically expressed in units such as pounds or kilograms. The weight of an object can vary depending on the gravitational force acting on it.

There are 16 ounces in a pound.

Thus, a 5/6 pound bag of candy weighs

5/6 × 16 = 13.3 ounces.

If you want to know the weight in grams, 13.3 ounces is equal to 377 grams.

The 95% confidence interval to estimate the proportion of students on financial aid = (0.522, 0.658)

In this question we have been given a university dean is interested in determining the proportion of students who receive some sort of financial aid.

Let p be the population proportion of students who receive some financial aid.

The dean randomly selects 200 students and finds that 118 of them are receiving financial aid.

i.e. n= 200

p{hat} = 118/200 = 0.59

We know that the critical value for 95% confidence interval : z = 1.96

The standard deviation would be,

σ = √[p{hat}(1 - p{hat})/N]

σ = √0.59(1 - 0.59)/200

σ = √(0.0012095)

σ = 0.0348

The 95% confidence interval for population proportion would be,

(0.59 ± (1.96 * 0.0348))

= (0.59 - (1.96 * 0.0348), 0.59 + (1.96 * 0.0348))

= (0.5218, 0.6582)

Therefore, the 95% confidence interval : (0.522, 0.658)

Answer: 75

Step-by-step explanation:

To divide a mixed number by a fraction, we need to convert the mixed number into an improper fraction and then multiply it by the reciprocal of the fraction.

Step 1: Convert the mixed number to an improper fraction:

7 5/6 = (6 * 7 + 5) / 6 = 47/6

Step 2: Multiply the improper fraction by the reciprocal of the fraction:

47/6 ÷ 2/3 = 47/6 * 3/2

Step 3: Simplify the fraction if possible:

47/6 * 3/2 = (47 * 3) / (6 * 2) = 141/12

Step 4: Simplify the fraction further, if necessary:

141/12 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 3:

141/12 = (141 ÷ 3) / (12 ÷ 3) = 47/4

Therefore, 7 5/6 ÷ 2/3 is equal to 47/4 or 11 3/4.

the final answer is 18y

Answer:

The mean is 40/3 ⇒ D

Step-by-step explanation:

The mean of a set of data = The sum of data ÷ the number of data

∵ A restaurant manager tracking the number of ketchup bottles in

  six weeks

∴ The number of data = 6

∵ The numbers of ketchup bottles used each week are 10, 14, 11, 10, 18, 17

→ Find their sum

∴ Their sum = 10 + 14 + 11 + 10 + 18 + 17

∴ Their sum = 80

∵ The mean = The sum of data ÷ the number of data

∴ The mean = 80 ÷ 6

→ Simplify it by dividing both by 2

∴ The mean = 40/3

Answer:

A=49 B=41

Step-by-step explanation:

First, find the angle next to 88 by subtracting it from 180 to get 92.Then add that to 39 to get 131. Then subtract that from 180 to get the missing angle for A.Then add that angle to 90 to solve for the bigger triangle's missing angle, or B. Once you get that value, which is 139, subtract that from 180 to get the value for angle B.

The semicircle's perimeter is 44.52 km.

A circle is a two dimensional figure with a radius and circumference of 2πr.

The area of a circle is π²r.

The area of a semicircle is πr²/2.

We have,

The diameter of a semicircle = 17.8 kilometers.

This means,

Radius of the circle.

= 17.8/2

= 8.51 km

Now,

The circumferecne of a circle = 2πr

The circumference of semiciircle.

= πr

And,

The semicircle's perimeter.

= πr + diameter

= 3.14 x 8.51 + 17.8

= 44.52 km

Thus,

The semicircle's perimeter is 44.52 km.

the null hypothesis using symbol:-

H₀ : μ = 11.80

the alternative hypothesis using symbol:-

H₁:  μ ≠ 11.80

This is a one tailed test. Given what you know, you will evaluate this hypothesis using a t test statistic.

Alpha level = 0.05

Sample size = n

Degree of freedom = n-1 = 40-1 = 39

To use the t distribution we will have to find the critical value from the t table this value is 1.685

Let x the amount invested in fund B, then, you have that fund B returned 0.1*x (10% of the investment ) and fund A returned 0.03*4000 = 120 (3% of the investment)

Moreover, both funds returned together 8%, that is, it returned

0.08*(x + 4000).

Now, consider that amount returned by both funds equal the sum of the amount returned by each fund, then, you have:

0.1x + 120 = 0.08(x + 4000) expand the factor right side

0.1x + 120 = 0.08x + 320 subtrac 0.08x and subtract 120 both sides

0.1x - 0.08x = 320 - 120 simplify like terms

0.02x = 200 divide by 0.02 both sides

x = 200/0.02

x = 10000

Hence, the investment in fund B was $10000

6:4:9 Yw❤️

Step-by-step explanation:

The form that most quickly reveals the y intercept is

The y intercept is (0, 21/2)

The y-intercept is the point where a function or a curve intersects the y-axis. In other words, it is the value of the dependent variable (y) when the independent variable (x) is equal to zero.

In the form,  f(x) = 1/2 x² - 5x + 21/2 it is easier to see that eliminating x by plugging in 0 leaves 21/2 which is the y intercept

hence we can easily say that the y intercept is (0, 21/2)

Answer: 0.5 meters because m=meters and meters/2 = 0.5

The required measure of the angle m∠2 is 138°.

Given that,
A bicycle path divides a rectangular park. The path makes a 42° angle with the top border of the park, so mZ1 = 42°. What is m/2 is to be determined.

The rectangle is 4 sided geometric shape whose opposites are equal in lengths and all angles are about 90°.

Here,
According to the question,
Let the measure be x,
Now the bicycle path divides the rectangular park,
So,
m∠1 + m∠2 = 180
42 + x =180
x = 180 - 42
x = 138°

Thus, the required measure of the angle m∠2 is 138°.
