Answer:

254.47 inches squared

Step-by-step explanation:

Area of a circle is

[tex]\pi {r}^{2} [/tex]

so to find the radius we half the diameter( which here is 18 inches) which equals to 9

we replace r to 9 because that's the radius

[tex]\pi \times {9}^{2} [/tex]

which is 254.47 inches squared

Answer:

[tex]Empty = \frac{5}{12}[/tex]

Step-by-step explanation:

Given

[tex]Water = \frac{1}{3}[/tex]

[tex]Oil = \frac{1}{4}[/tex]

Required

The fraction that is empty

The constituent of the water can be represented as:

[tex]Water + Oil + Empty = 1[/tex]

Make Empty the subject

[tex]Empty = 1 - Water - Oil[/tex]

Substitute values for Water and Oil

[tex]Empty = 1 - \frac{1}{3} - \frac{1}{4}[/tex]

Take LCM

[tex]Empty = \frac{12 - 4 - 3}{12}[/tex]

[tex]Empty = \frac{5}{12}[/tex]

Answer:

You paid $40.25 in total.

Step-by-step explanation:

In this question:

Spending of 35%

Tip of 15% means that 15% of 35 will be added to your total spending. So

[tex]T = 35 + 0.15*35 = 35 + 5.25 = 40.25[/tex]

You paid $40.25 in total.

An exponential function in the form y= abt that represents the situation.

y  = 60.75.

Correlation coefficient is a measure of how similar two datasets are acting.

The range of correlation coefficient is [-1, 1]

When the correlation coefficient comes out as -1, it means that both the datasets are negatively oppositely correlated. One data increases, other data starts decreases in the opposite direction.

When the correlation coefficient comes out below 0, values are negatively correlated.

If the correlation coefficient comes out as 0, that means both the data sets are uncorrelated with respect to how we compare them.

When the correlation coefficient comes out > 0, that means both datasets' values are positively correlated.

If correlation coefficient comes out as 1, then the values grow exact similarly, in the same direction.

Given;

y = -0.4x + 98.3

When you increase your homework score by 1 point, you lose 0.4 points on your test.

-0.4x + 98.3 = 74

→  -0.4x = -24.3  

→  x = 60.75 ≈ 61

Therefore, the correlation will be y=61.

=============================================

Explanation:

The first sentence tells us what the population is: it's the set of all her students. She's not concerned with any other students in any other classroom. So her "universe", so to speak, is solely focused on this classroom only. Once the population is set up, a sample of it would be a subset of the population.

If set A is a subset of set B, then everything in A is also in B, but not vice versa. For example, the set of humans is a subset of the set of mammals because all humans are mammals. However, a dog is a mammal but not a human. This shows that A is a subset of B, but not the other way around. In this example, A = humans and B = mammals.

Going back to the classroom problem, we have A = sample and B = population. If Ms. Lee has 30 students, and she randomly selects 5 of them, then those 30 students make up set B and the 5 selected make up set A. Selecting the names randomly should generate an unbiased sample. This sample should represent the population overall. If the population is small enough, the teacher could do a census and not need a sample. Though there may be scenarios that it's still effective to draw a sample.

Answer:

x=19.55

hope it help you..

Answer:

19.55

Step-by-step explanation:

x/8.5 = 2.3

x = 8.5 × 2.3

x = 85 × ⅒ × 23 × ⅒

x = 85 × 23 × ⅒ × ⅒

x = 1955 × 1/100

x = 1955/100

x = 19.55

Answer:

  1.1π radians/second

Step-by-step explanation:

Each revolution is 2π radians, and there are 60 seconds in a minute. The rotation rate is ...

  (33 rev/min)×(2π rad/rev)×(1 min)/(60 sec) = 66π/60 rad/sec

  = 1.1π rad/sec

The angular speed is 1.1π radians per second.
