Evaluate: 94/5 x 31/2. Step by step please :)

The critical value zα/2 that corresponds to a 83% confidence level is 1.37.

The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:

[tex]z=\frac{x-\mu}{\sigma} \\\\where\ x=raw\ score,\mu=mean,\sigma=standard\ deviation[/tex]

Given that the confidence level (C) = 83% = 0.83

α = 1 - C = 0.17

α/2 = 0.17/2 = 0.085

The z score of α/2 corresponds with the z score of 0.415 (0.5 - 0.085) which is equal to 1.37

Answer:

8 hours = 7,829 toy spinners

24 hours= x toy spinner

7829 / 24 x 8

2069 for one hour

Step-by-step explanation:

so your answer is this hope this helps good luck if it does not i am sorry

The number of toy spinners the machine make each hour is 2068.

Given that, the machine makes 7,829 toy spinners in 1 day.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Here,

8 hours = 7,829 toy spinners

24 hours= x toy spinner

Now, number of toys in one hour = 7829/(24×8)

= 2069.66

= 2069 per one hour

Therefore, the number of toy spinners the machine make each hour is 2069.

Answer:

 If there is a system of magnets being held in place, there is potential energy

Step-by-step explanation:

pretty sure you've seen this answer before but 8ts right so just go along with it ok bud?

Answer:

Okay

Magnets work because opposite poles are attracted to each other, this is how the objects move (depending on how the atoms and how to iron is, it could be much stronger or weaker)

If there is a system of magnets there is potential energy, when you let go of the magnets (or when they stick together) it converts the potential energy to kinetic energy because it moved.

Answer:

it's 3. how could u not know that 0.4 x 3 = 1.2 duh

The value of the expression is 3.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

1.2 ÷ 0.4

= 1.2 / 0.4

The decimal point gets canceled.

= 12/4

= 3

Thus,

The value of the expression is 3.

1400= 100b divide both sides by hundred

-b = 14

For n

25/100= 7/n cross multiply

25n = 700 divide both sides by 25

Answer:

429.4 cubic units

Step-by-step explanation:

Volume of a cone = pi*r^2*(h/3)

height = 9

radius = 6.75

pi*6.75^2*(9/3) = pi*45.5625*3 = 136.6875pi

136.6875*pi is around 429.416 -> rounded = 429.4

Answer:

See answer below.

Step-by-step explanation:

[tex]V = \frac{1}{3} \pi r^2h[/tex]

[tex]V = \frac{1}{3}\pi (6.75)^2(9)[/tex]
