Q1: A factory produces candy bars, with mean weight 5 grams. After the machines were updated with new tech, a worker worries the candy bars are now lighter on average. To test this theory, the worker collects a random sample of candy bars and measures their mean weight. Identify the null and alternative hypotheses in this situation.

Answers

The null hypothesis in this situation is the mean weight of the candy bars is not lighter.

The alternative hypothesis in this situation is the mean weight of the candy bars is lighter.

What is a hypothesis?

A hypothesis is an idea that gives a temporary explanation to a phenomena which would be proved or disapproved by carrying out an experiment .

The null hypothesis states that there is no relationship between the population parameters. It is known as the true hypothesis. The alternative hypothesis states that there is a relationship between the population parameters.

Answer:

Missing numerator = 6

Step-by-step explanation:

Let us assume that,

→ Missing numerator = x

Now we have to,

→ Find the required value of x.

Forming the equation,

→ 2/5 = x/15

Then the value of x will be,

→ 2/5 = x/15

→ 2 × 15 = x × 5

→ 30 = 5x

→ 5x = 30

→ x = 30/5

→ [ x = 6 ]

Hence, the value of x is 6.

Answers

Answer:

4 quarters, 10 dimes

Step-by-step explanation:

x + y = 14 --> x = 14 - y

$0.10x + $0.25y = $2.00, or 10x + 25y = 200

- we can plug this value for x from the first equation into the second:

10(14 - y) + 25y = 200

140 - 10y + 25y = 200

140 + 15y = 200

15y = 60

y = 4 --> 4 quarters ($0.25 x 4 = $1.00)

if y = 4, then x = 14 - y --> x = 10 --> 10 dimes (0.10 x 10 = $1.00)

matches the second equation where these add up to $2.00

Answer:

1 way is 10 dimes and 4 quartes

Answer:

a = 12

b = 6

Step-by-step explanation:

You have a 30°-60°-90° triangle which is a special right triangle. We memorize the ratios of the sides and can find the sides given just one side, by using the relationships between the sides, so we don't have to use trig ratios.

Generally, the LONGEST side (hypotenuse) is twice the shortest side. Or, the SHORTEST side is half the longest side (hypotenuse). The LONGER LEG is the short leg × sqrt(3).

Or the SHORT LEG is the

longer leg/sqroot(3)

You are given the long leg here. You have:

Long leg = 6sqroot(3)

So the short leg must be 6.

bc, longer leg IS Short leg×sqroot(3)

short leg =6

Then the LONGEST side (hypotenuse) has to be twice that.

LONGEST side = 12

Where it says "Prove side c" maybe that is like doing a check.

6^2 + (6sqrt3)^2 = 12^2

36 + 108 = 144

144=144

What is area of shaded

Answers

Answer:225

Step-by-step explanation:

we start by finding the area of the unshaded triangles and subtracting them from the total area of the box.

The total length of the top is 20 and the total length of the bottom side is 18

20-18=2 so the small unshaded part on the bottom side is 2. with this we can find the left triangle. triangle area is base times height over 2 so the area of the unshaded triangle on the left is 15*2/2=15.

We know the small unshaded bit on the right side is 6 as it is shown on the diagram. again, we can use base times height over 2 to get the area of the top unshaded triangle. 6*20/2= 60.

We can do base times height to find the total area of the rectangle

15*20=300

300-15-60=225

The distance from tree 1 to tree 3 is about 205 meters.

Equation

An equation is an expression used to show the relationship between two or more variables and numbers.

Let a represent the distance from tree 1 to 2, b from 2 to 3 and c from tree 3 to 1.

Hence:

a + b = 335

Also:

b + c + a = 540

a + b + c = 540

335 + c = 540

c = 205 meters

The distance from tree 1 to tree 3 is about 205 meters.
