Answer 1

Answer: 216 in

Step-by-step explanation: I used the formula A=1/2(b1+b1)h and I filled it in by doing A=1/2(6+12)6 and then I divided the height by 1/2 and i multiplied 72 by 3 which is 216 in.

A lab is testing the amount of a certain active chemical compound in a particular drug that has been recently developed. The manufacturer claims that the average amount of the chemical is 95 mg. It is known that the standard deviation in the amount of the chemical is 5 mg. A random sample of 25 batches of the new drug is tested and found to have a sample mean concentration of 89.9 mg of the active chemical.
Calculate the 95% confidence interval for the mean amount of the active chemical in the drug. Give your answers to 2 decimal places. (suppose to be number less than and equal to mean less than and equal to another number)

Answers

Answer:

The 95% confidence interval is "87.94, 91.86".

Step-by-step explanation:

The given values are:

Sample batches,

n = 25

Sample mean concentration,

[tex]\bar{x}[/tex] = 89.9 mg

Amount of chemical,

σ = 5

α = 0.05

The critical value from Z table will be:

=  [tex]Z(\frac{\alpha}{2} )[/tex]

=  [tex]Z(\frac{0.05}{2} )[/tex]

=  [tex]1.96[/tex]

Now,

The confidence interval will be:

=  [tex]\bar{x} \pm Z(\frac{\alpha}{2} )\times \frac{\sigma}{\sqrt{n} }[/tex]

On substituting the values, we get

=  [tex]89.9 \pm Z(\frac{0.05}{2})\times \frac{5}{\sqrt{25}}[/tex]

=  [tex]89.9 \pm Z(\frac{0.05}{2})\times \frac{5}{5}[/tex]

=  [tex]89.9 \pm1.96\times 1[/tex]

Lower limit will be:

=  [tex]89.9 -1.96\times 1[/tex]

=  [tex]87.94[/tex]

Upper limit will be:

=  [tex]89.9 +1.96\times 1[/tex]

=  [tex]91.86[/tex]

isosceles right

scalene acute

scalene right

equilateral right

Answers

Answer:

scalene right

Step-by-step explanation:

A scalene right has no equal side lengths, has a right side(90) and will have two angles less than 90 because all three triangle sides need to equal to be 180. So scalene right is your answer. Hope that helped!

In the last several weeks, 18 days saw rain and 29 days saw high winds. in the same time period 7 days saw both rain and high winds. How many days saw either rain or high winds

Answers

Answer:

40 days saw either rain or high winds

Step-by-step explanation:

We solve this question using Venn sets.

I am going to say that:

Set A: Rain

Set B: High winds.

18 days saw rain

This means that [tex]A = 18[/tex]

29 days saw high winds

This means that [tex]B = 29[/tex]

7 days saw both rain and high winds.

This means that [tex]A \cap B = 7[/tex]

How many days saw either rain or high winds?

This is

[tex]A \cup B = A + B - A \cap B[/tex]

Sp

[tex]A \cup B = 18 + 29 - 7 = 40[/tex]

40 days saw either rain or high winds

What are the three ordered pairs that should be in the table of values y=2x-3

Answers

Answer:

(-2, -7), (0, -3), (2, 1)

Step-by-step explanation:

Equation is given as y = 2x - 3.

To complete the table, plug in each value of x into y = 2x - 3 to get their corresponding y-value.

✔️When x = -2:

y = 2(-2) - 3

y = -4 - 3

y = -7

✔️When x = 0:

y = 2(0) - 3

y = -3

✔️When x = 2:

y = 2(2) - 3

y = 4 - 3

y = 1

To the nearest 1000, there are 18,000 people at a festival . Write down the minimum possible number of people at the festival

Answers

Answer:

17500

Step-by-step explanation:

17499 rounds down

17500 rounds up

The number of people is an illustration of approximation and estimation

The minimum possible number of people at the festival is 17500

The approximated number of people is:

People  = 18000

Because 18000 represents people, it means that the population is a whole number

The smallest whole number that can be approximated to 18000 is 17500

i.e.

People = 17500

Hence, the minimum possible number of people at the festival is 17500

Answer:

Four (4); 45; at least; 181.

Step-by-step explanation:

Ali has four friends that owe him x dollars each. His parents owe him $45 for doing chores last week. He recalls that people owed him at least $181.

To find how much money each of Ali's friends owe him;

Given the algebraic expression;

4x + 45 ≤ 181

4x ≤ 181 - 45

4x ≤ 36

Dividing both sides by 9, we have;

x ≤ 9

Therefore, Ali's friends owe him at least $9 each.

Four (4); 45; at least; 181.

Answers

Answer:

[tex]A" = (3,2)\ \ B" = (-1,1)\ \ C" =(-3,4)\ \ D =(-1,4)[/tex]

Step-by-step explanation:

Given [Missing]

[tex]A = (-3,4)[/tex]

[tex]B = (1,3)[/tex]

[tex]C =(3,6)[/tex]

[tex]D =(1,6)[/tex]

The first transformation: reflection across the y-axis.

The rule is: [tex](x,y)==>(-x,y)[/tex]

So:

[tex]A = (-3,4)[/tex] ==>[tex]A' = (3,4)[/tex]

[tex]B = (1,3)[/tex] ==> [tex]B' = (-1,3)[/tex]

[tex]C =(3,6)[/tex] ==> [tex]C' = (-3.6)[/tex]

[tex]D =(1,6)[/tex] ==> [tex]D' = (-1,6)[/tex]

Translation 2 units down

The rule is: [tex](x,y)==>(x,y-2)[/tex]

So:

[tex]A' = (3,4)[/tex] ==> [tex]A" =(3,4-2) =(3,2)[/tex]

[tex]B' = (-1,3)[/tex] ==> [tex]B" = (-1,3-2) = (-1,1)[/tex]

[tex]C' = (-3.6)[/tex] ==> [tex]C" = (-3,6-2) = (-3,4)[/tex]

[tex]D' = (-1,6)[/tex] ==> [tex]D" =(-1,6-2) = (-1,4)[/tex]

Hence:

[tex]A" = (3,2)\ \ B" = (-1,1)\ \ C" =(-3,4)\ \ D =(-1,4)[/tex]
