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

Answer:
Correct
Step-by-step explanation:
Just divide both the numerator and the denominator by their common factors.
First of all factor both of the numbers.
405=5*3^4
450=5^2*3^2*2
Now line it up.
5*3*3*3*3

Answer:
(-infinity, 9]
Step-by-step explanation:
The solution of the inequality is w ≤ 9 and the graph is attached.
What is an inequality?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

if mary smith and karen white have identical sat scores and quality of letter, but mary smiths high school gpa is 1.5 point higher than karen, how much higher will marys college gpa be than karens
Required table is attached below :
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

The number of cans the soup kitchen has is represented by the equation, y = -63x + 825, where x represents the number of days and y represents the number of cans. How many cans will the soup kitchen have left after 10 days?
Answer:
195 cans
Step-by-step explanation:
Start by multiplying -63 by 10, since 10 should be in place of x. You will get -630. Add 825 to -630 and you will get 195.

A researcher wants to make a 99% confidence interval for a population proportion. A preliminary sample produced the sample proportion of 0.46. The sample size that would limit the margin of error to be within 0.061 of the population proportion is:
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
A company produces only one type of light bulbs. The light bulbs are being manufactured two factories: Factory A and Factory B. Factory A produces 10, 000 bulbs every year, while Factory B produces 2, 000. Also 2% of bulbs from Factory A are defective while 1% of bulbs from Factory B are. After production all bulbs are brought to the same facility and shipped to retail stores.
Required:
a. What is the probability that a bulb bought from a store is defective?
b. Given that the bulb is defective, what is the probability that it was produced by Factory A?
c. Given that the bulb is functional, what is the probability that it was produced by Factory A?
Answer:
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]

A. Quadratic Polynomial
B. None of the answers apply.
C. Cubic Trinomial
D. Polynomial
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
