Solve the two-step equation.

14 = 31.7 – 3x

What is the solution?

Answer:

The .79 correlation is strong and positive, but "significan" is a question not answered by the correlation coefficient.  Many people mistake correlation for causation--one variable's change causing the other variable to change.

Pick the second answer.

Answer:

$12

Step-by-step explanation:

50% means half of something. Like 50% of 20 is 10. 100% means the whole number. So, 50% is half of the number.

24 divided by 2 is 12.

Yes, it is

Step-by-step explanation:

Given

The attached image

Required

Is AB a tangent to the circle

From the attached circle, we can see that AP is the radius of the circle P.

And by definition, a tangent touches the circle at only one point.

Since AB touches the circle at only point A, then AB is a tangent.

Following are the responses to the given question:

Step-by-step explanation:

Given:

[tex]\to f(x,y)=xy\\\\\to 48x^2+3y^2=3456\\\\[/tex]

let [tex]\phi(x,y)=48x^2+3y^2=3456[/tex]

using the lagrange multiplies:

[tex]\bigtriangledown f=\lambda \bigtriangledown \phi\\\\i)\ \ y=96 \lambda x \to \lambda=\frac{y}{96\ x} \\\\ii)\ \ x=6 \lambda y \to \lambda=\frac{y}{6\ y} \\\\iii)\ \ 48x^2+3y^2=3456\\\\[/tex]

From equation (i) and (ii)\\\\

[tex]\to \frac{y}{96x}=\frac{x}{6y}\\\\\to 6y^2=96x^2\\\\\to 3y^2=48x^2\\\\[/tex]

From equation 3:

[tex]48x^2+48x^2=3456\\\\96x^2 3456\\\\x^2=36\\\\x=\pm 6\\\\\therefore 3y^2=48(36)\\\\3y^2=1728\\\\y^2=576\\\\y=\pm24\\\\(x,y)=(\pm 6,\pm 24)\\\\Maximum \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 144 \ \ \ \ at \ \ (6,24) \ \ \ \ \ \ \ and \ \ \ \ \ \ (-6, -24) \\\\Minimum \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ -144 \ \ \ \ at \ \ (-6,24) \ \ \ \ \ \ \ and \ \ \ \ \ \ (6,-24)\\\\[/tex]

Answer:

A. We are​ 99% confident that the interval from 4.1 to 5.6 actually does contain the true value of population mean.

Step-by-step explanation:

x% confidence interval:

A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.

In this question:

99% confidence interval means that we are 99% sure that this interval contains the population mean.

Interval between 4.1 and 5.6.

So the correct answer is given by option A.

Answer:

12.25π m²

Step-by-step explanation:

Circumference = Diameter x pi

Area = radius squared (^2) x pi

7 divided by 2 = 3.5

3.5^2 = 12.25

12.25π

Answer:

A ≈ 3.9

Step-by-step explanation:

How to solve

A=πr2

C=2πr

A=C2

4π = 72

4·π ≈ 3.8993

Therefore, the circle in square meters in the nearest tenths is A ≈ 3.9

Answer:

Step-by-step explanation:

2[tex]\pi[/tex]r = circumference

2[tex]\pi[/tex]r = 8.5 cm

[tex]\pi[/tex]r = 4.25 cm

r = 1.352817 cm

d = 2r

d= 2.705

diameter = 2.7 cm

Answer:

2/3

Step-by-step explanation:

2 (−2/3) (1/2) + 3 (−2/3)^2

= −4/3 (1/2) + 3 (−2/3)^2

= −2/3 + 3 (−2/3)^2

= −2/3 + 3 (4/9)

= −2/3 + 4/3

= 2/3

Answer:

Answer:

C. p - 7 + 22 = 22 - 7

D. p - 7 + 7 = 22 - 22

Step-by-step explanation:

p - 7 = 22

Add 7 to both sides

p = 29

An equivalent equation could be;

-7 = 22 - p

m = slope

b = y-intercept

y = 3/4x - 2

Answer:

D) 1078

Step-by-step explanation:

Answer:

The null hypothesis is: [tex]H_{0}: \mu = 100[/tex]

The alternative hypothesis is: [tex]H_{a}: \mu > 100[/tex]

Step-by-step explanation:

At the null hypothesis, we test if the mean is equal to a certain value.

At the alternate hypothesis, we test if the mean is less than, more than, or different from the value tested at the null hypothesis.

The tuft bind strength of a synthetic material used to make carpets is known to have a mean of 100 lb and standard deviation of 20 lb.

This means that the null hypothesis is: [tex]H_{0}: \mu = 100[/tex]

Could it be that the average tuft strength is above 100 lb?

The world above means that the appropriate alternative hypothesis is: [tex]H_{a}: \mu > 100[/tex]
