A den has a circular rug. According to the tag, the rug has an area of 3.14 square meters.

Answer:

Step-by-step explanation:

[tex]d^2=(x_2-x_1)^2+(y_2-y_1)^2\\ \\ d^2=(-2-1)^2+(5-9)^2\\ \\ d^2=9+16\\ \\ d^2=25\\ \\ d=\sqrt{25}\\ \\ d=5[/tex]

Answer:

PQ = 5

Step-by-step explanation:

Distance Formula

d = [tex]\sqrt{(x_{2} - x_{1})^2 + (y_{2} - y_{1})^2 }[/tex]

d = [tex]\sqrt{{(1} - -2)^2 + (9 - 5)^2 }[/tex]

d = [tex]\sqrt{3^2+4^2}[/tex]

d = [tex]\sqrt{9+16}[/tex]

d =[tex]\sqrt{25}[/tex]

d=5

PQ = 5

Answer:

the sample size that would limit margin of error is 443

Step-by-step explanation:

The confidence level = 99 percent = 0.99

1 - alpha = 0.99

Alpha = 1 - 0.99

= 0.01

The critical z value for alpha = 0.01 = 2.576

Sample proportion = 0.46

Margin of error E = 0.061

Sample size = p(1-p)(Z/E)²

= 0.46(1-0.46) x (2.576/0.061)²

= 0.46(0.54)(42.23)²

= 0.2484 x 1783.37

= 442.989

= 443

The sample size would be 443

Answer:

195 cans

Step-by-step explanation:

Answer:

(-infinity, 9]

Step-by-step explanation:

The solution of the inequality is w ≤ 9 and the graph is attached.

In Algebra, inequality is a Mathematical statement that shows the relation between two expressions using the inequality symbol. The expressions on both sides of an inequality sign are not equal.

Given is an inequality, 8w ≤ 72, we need to graph it,

8w ≤ 72

Divide by 8 on both sides

w ≤ 9

For graph, draw a number line and label a point as 9.

Draw a solid line facing to the left and having a closed point at 9.

The line should not extend past 9.

Hence, the solution of the inequality is w ≤ 9

The correct pairs which represent the pair of ratios will make a proportion are,

(A) 2/3 and 4/9

(B) 5/15 and 4/12

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.

We have to given that;

The pairs of ratio are,

(A) 2/3 and 4/9

(B) 5/15 and 4/12

(C) 4/12 and 6/24

Now,

From option A;

⇒ 2/3 and 4/9

⇒ 4/ 9 = 2/3

Hence, It make a proportion.

(B) 5/15 and 4/12

5 / 15 = 1 / 3

4 /12 = 1 / 3

Hence, It make a proportion.

(C) 4/12 and 6/24

4/12 = 1/3

6/24 = 1/4

Hence, It don't make a proportion.

Thus, The correct pairs which represent the pair of ratios will make a proportion are,

Answer:

0.56

Step-by-step explanation:

Since they both have :

SAT score is the same ; quality of letter is the same ;

High school GPA is 1.5 points higher ;

Therefore, to determine how much Mary's GPA will be higher than Karen's :

Multiply the number of points by the Coefficient of high school GPA Given in the regression table attached below :

High school GPA Coefficient = 0.37635

Number of points = 1.5

= 1.5 * 0.37635

= 0.564525

= 0.56

Answer:

Y = 21 when x=18

X varies 3 numbers subtracted from Y so now it comes as x= 18 then y is plus 3 the the number shown on x which is 18+3 then you get 21.

Answer:

C) Cubic Trinomial

Step-by-step explanation:

First, we combine like terms to simplify the polynomial. Like terms means having the same variable and exponent.

We get this expression: b^3+4b^2+25

There are 3 terms in this polynomial. Thus, it classifies as a trinomial. And its highest degree is 3, so it’s a cubic trinomial

Follows are the solution to the given points:

Step-by-step explanation:

Given values:

[tex]P(\frac{D}{A})=0.02 \\\\P(\frac{D}{B})=0.01\\\\P(A)=\frac{10,000}{10,000+2000} =\frac{10}{12} =\frac{5}{6} \\\\P(B)=\frac{1}{6}\\\\[/tex]

For point a:

[tex]P(D) =p(D\cap A) +P(D \cap B)\\\\[/tex]

         [tex]=P(\frac{D}{A}) \times P(A) + P(\frac{D}{B}) \times P(B)\\\\=0.02 \times \frac{5}{6} + 0.01 \times \frac{1}{6}\\\\=\frac{0.1}{6} + \frac{0.01}{6}\\\\=\frac{0.1+0.01}{6} \\\\=\frac{0.11}{6} \\\\=\frac{11}{600} \\\\=0.0183[/tex]

For point b:

[tex]P(\frac{A}{D})= \frac{P(\frac{D}{A}) \times P(A)}{P(D)}\\\\[/tex]

         [tex]= \frac{0.02 \times \frac{5}{6}}{\frac{11}{600}}\\\\= \frac{0.02 \times \frac{5}{6}}{0.0183333333}\\\\= \frac{0.02 \times 0.833333333}{0.0183333333}\\\\= \frac{0.0166666667}{0.018}\\\\=0.9090 \approx 0.0991[/tex]

For point c:

[tex]P(\frac{A}{D^C})=\frac{P(\frac{D^c}{A}) \times P(A)}{P(D^c)}\\\\[/tex]

           [tex]= \frac{1-0.02 \times \frac{5}{6}}{1- \frac{11}{600}}\\\\= \frac{0.98 \times \frac{5}{6}}{0.98}\\\\=\frac{5}{6}\\\\=0.833[/tex]

x = 3

Step-by-step explanation:

6x - 5 + 7x = 34

Find x

______________

To solve this, we need to isolate x :

First add like terms :

6x + 7x

13x

13x - 5 = 34

Add 5 to both sides :

13x = 39

Divide 13 from both sides to get x alone :

x = 3

Answer:

x=3

Step-by-step explanation:

Start by moving the 5 over creating 6x+7x=34+5. Then add them together 13x=39. And now simplify x=3
