Answer:

The Scatter Plot is shown below:

Step-by-step explanation:

Scatter Plot is the graphical representation of two-dimension data. It is plot to see the relation between two data values.

Here both X and Y has discrete or continuous data types.

By the scatter plot, we see that as we increase the value of X, value of Y also get increases. Thus, both has Positive Correlation.

Answer:

0.8 and 1.1 are outliers of the given data set.

Step-by-step explanation:

The given data set is

5.8, 6.1, 4.9, 10.9, 0.8, 6.1, 7.4, 10.2, 1.1, 5.2, 5.9

Arrange the data set in ascending order

0.8, 1.1, 4.9, 5.2, 5.8, 5.9, 6.1, 6.1, 7.4, 10.2, 10.9

Divide the data in four equal parts.

(0.8, 1.1), 4.9,( 5.2, 5.8), 5.9,( 6.1, 6.1), 7.4, (10.2, 10.9)

From the above division we get,

[tex]Q_1=4.9[/tex]

[tex]Median=5.9[/tex]

[tex]Q_3=7.4[/tex]

The interquartile range of the data is

[tex]IQR=Q_3-Q_1[/tex]

[tex]IQR=7.4-4.9=2.5[/tex]

If all the data elements lies in the interval [Q₁-1.5(IQR),Q_3+1.5(IQR)], then the data set has no outliers.

[tex][Q_1-1.5(IQR),Q_3-1.5(IQR)]=[4.9-1.5(2.5),7.4-1.5(2.5)]=[1.15,11.15][/tex]

Since all the elements lie in the interval [1.15,11.15] except 0.8 and 1.1, therefore 0.8 and 1.1 are outliers.

how to solve -6<-2x<14

Answers

Hey there! :) 

-6 < -2x < 14

We're trying to solve for x. To solve for x, we must isolate x.

So, let's divide everything by -2!

-6 ÷ -2 < -2x ÷ -2 < 14 ÷ -2

**Remember : when dividing by a negative number, you MUST switch the sign! So, if the sign is ">" then we switch it to "<" and the other way around **

3 > x > -7

So, our answer is : → 3 > x > -7

A bargain bin contains classical and rock and CDs. There are 60 CDs in the bin. Choosing a rock CD have the same number of favorable outcomes. How many rocks CDs are in the bin

Answers

Final answer:

The bin should contain 30 rock CDs, which constitutes half of the total CDs (60). This conclusion is reached by dividing the total number of CDs by 2, as the question implies an equal probability of picking a rock or classical CD.

Explanation:

The question pertains to the concept of probability in mathematics. Here, the total number of CDs is specified as 60. If choosing a rock CD has the same number of favorable outcomes, it means that half of the CDs are rock CDs (as the other half would then be classical CDs). So, to find the number of rock CDs in the bin, you simply divide the total number of CDs by 2. Here, 60 CDs divided by 2 equals 30. Thus, there are 30 rock CDs in the bin.

Find the difference. express your answer in simplest form. (2s/s^2-4s+4) - (4/s^2-4s+4)

Answers

To find the difference, we are going to destroy the parenthesis first, and then, we are going to perform the operations. Remember that to destroy a parenthesis preceded by a negative sign (-), you should change the signs of the factors inside the parenthesis:
[tex] \frac{2s}{s^2-4s+4} -( \frac{4}{s^2-4s+4} )[/tex]
[tex]\frac{2s}{s^2-4s+4} -\frac{4}{s^2-4s+4}= \frac{2s-4}{s^2-4s+4} [/tex]

Now we can factor both numerator and denominator and simplify:
[tex]\frac{2s-4}{s^2-4s+4} = \frac{2(s-2)}{(s-2)^2} = \frac{2}{s-2} [/tex]

We can conclude that the difference in simplest form is: [tex] \frac{2}{s-2} [/tex]
To get started, combine -4s+4 with 4s - 4.  Result:  0.  That leaves

 2s        4          2(s+2)

the initial number of bacteria in a culture is 12,000. the xulture doubles each day write an exponential functin to model the population Y of bacteria after X days

Answers

The equation would be y=12000(2)ˣ.

This equation is of the form y=a*bˣ, where a is the initial population and b is the rate that it increases by.  In this problem, a = 12000 and b=2, since it doubles each time.

Answer:

[tex]Y = 12,000 \cdot (2)^X[/tex]

Step-by-step explanation:

The exponential function is given by:

[tex]y =a \cdot b^x[/tex]

where,

a is the initial values and b is the growth factor.

As per the statement:

The initial number of bacteria in a culture is 12,000.

⇒Number of bacteria initially(a) = 12,000

It is also given that the culture doubles each day.

⇒ growth factor [tex]b= 2[/tex]

We have to find the exponential function to model the population Y of bacteria after X days.

By definition of exponential function:

[tex]Y = 12,000 \cdot (2)^X[/tex]

where, x represents the days and Y is the population after X days.

Therefore,  an exponential function to model the population is,

[tex]Y = 12,000 \cdot (2)^X[/tex]

Which characteristics best describe an obtuse isosceles triangle? I. One angle is greater than 90°. II. All side lengths are equal. III. Two sides meet at a 90° angle. IV. Two sides are equal in length. A. I and IV B. II and III C. I and II D. III and IV

Answers

An obtuse triangle is a triangle that has an angle greater than 90 degrees, so 1. One angle is greater than 90 degrees is correct.

An obtuse isosceles triangle is defined as a three-sides triangle shape that has one angle (out of three angles) more than 90 degrees and whose two sides are always congruent that includes obtuse angle in between. So it will follow :-

⇒ Obtuse means "one angle is greater than 90 degrees".

⇒ Isosceles means "Two sides are equal in length".

So, option A is correct, i.e. statements I and IV.

the annual health insurance premium for Ms. Everett is $12,304 her employer says 70% of the premium and deducts the remainder from her paycheck Ms. Everett is paid monthly what amount is deducted from Ms. Everett paycheck for her health insurance premium.

$141.97
$307.60
$331.26
$717.73

Answers

Ms. Everett will be responsible for paying 30% of her annual premium of $12,304.  (12,304 X .30)

Her portion will be $3,691.20

If you spread that out over 12 months (3,691.20/12) it comes out to $307.60

To find the amount deducted from Ms. Everett's paycheck for her health insurance premium, calculate 70% of the annual premium, subtract the employer's contribution, and divide by 12 for the monthly deduction, resulting in $307.60. The correct answer is B.

To calculate the amount deducted from Ms. Everett's paycheck for her health insurance premium, first, find 70% of the annual premium:

70% of $12,304 = 0.70 x $12,304 = $8,612.80

The remainder that Ms. Everett must pay is the annual premium minus the employer's contribution: $12,304 - $8,612.80 = $3,691.20

Since Ms. Everett is paid monthly, divide the annual amount by 12 to find the monthly deduction: $3,691.20 ÷ 12 = $307.60

Therefore, the amount deducted from Ms. Everett's paycheck for her health insurance premium is $307.60.

a number is chosen at random from 1 to 50. find the probability of selecting divisors of 12

Answers

Hi! 

First of all, we need to know how many divisors 12 has. 

12: 1, 2, 3, 4, 6, 12

Since there are 6 divisors of 12, this means the probability is 6/50. 

You could just stick with 6/50 as your answer, but most probability is measured in percents so we'll convert 6/50 into a percent. 

Percents are measured out of 100, so to make 6/50 into a percent we need to do some cross-multiplying. 

[tex] \frac{6}{50} = \frac{x}{100} [/tex]

First, multiply 6 by 100

6 × 100 = 600

Next, divide the product by 50.

600 ÷ 50 = 12

So, your final answer is:

As a ratio:

[tex] \frac{6}{50} = \frac{12}{100} [/tex] 

As a fraction:

12/100 or 6/50

As a percent:

12%

Which graph represents the given inequality?
y > 4x - 2

Answers

In each graph, take a any point on either side and substitute in  the inequality. Then check if it satisfies the inequality. 
For graph 1, take a point (0,0).
substituting it we get,

y>4x-2   ⇒ 0>-2. This is true yet the region where (0,0) is, is shaded. So, wrong graph.

For graph 2, take point (0,0).
y>4x-2   ⇒ 0>-2. This is true but againt the region is shaded. so, wrong graph.

For graph 3, take point (0,0)
y>4x-2   ⇒ 0>-2. This is true. Since the point (0,0) is in this region, which is not shaded, it means that this is the required region. The correct graph is graph 3.

 PQ bisects ∠SPY. m∠SPQ =[tex] \frac{11}{2} [/tex] x-5 and m∠YPQ= 4x- [tex] \frac{5}{2} [/tex]

Solve for x and find m∠SPY

Answers

x = 5/3 and m∠SPY = 8 1/3°.

Since PQ bisects the angle, the two angles formed by the bisector are equal:

11/2x - 5 = 4x - 5/2

We will first multiply everything by 2 to eliminate the fractions:
(11/2x)*2 - 5*2 = 4x*2 - (5/2)*2
11x - 10 = 8x - 5

Subtract 8x from each side:
11x - 10 - 8x = 8x - 5 - 8x
3x - 10 = -5

Add 10 to both sides:
3x - 10 + 10 = -5 + 10
3x = 5

Divide both sides by 3:
3x/3 = 5/3
x = 5/3

Now we will plug this in for x in both smaller angles and add them together to find the measure of ∠SPY:

11/2(5/3) - 5 + 4(5/3) - 5/2
55/6 - 5 + 20/3 - 5/2

We will rewrite everything using a denominator of 6:
55/6 - 30/6 + 40/6 - 15/6 = (55-30+40-15)/6 = 50/6 = 8 2/6 = 8 1/3°
