If the product of two integers is zero, then which of the following MUST be true?
A) Both of the Integers are zero
B) At least one of the integers is zero
C) The sum of the two integers is zero
D) The difference of the two integers is zero
Answer:
B
Step-by-step explanation:
Anything times zero is zero, so any whole number can be the second one so long as the first is 0.
The sum doesnt have to equal zero because non zero numbers multiplied by zero still equal zero.

Find the standard deviation of the given data rounded to the nearest hundredth. 5.6, 5.2, 4.6, 4.9, 5.7, 6.4
Answer:
Standard deviation = 0.59
Step-by-step explanation:
Given data → 5.6, 5.2, 4.6, 4.9, 5.7, 6.4
Mean of the given data = [tex]\frac{5.6+5.2+4.6+4.9+5.7+6.4}{6}[/tex]
= 5.4
Data (x) (x - mean) (x - mean)²
5.6 5.6 - 5.4 = 0.2 (0.2)² = 0.04
5.2 5.2 - 5.4 = -0.2 (-0.2)² = 0.04
4.6 4.6 - 5.4 = -0.8 (-0.8)² = 0.64
4.9 4.9 - 5.4 = -0.5 (-0.5)² = 0.25
5.7 5.7 - 5.4 = -0.3 (-0.3)² = 0.09
6.4 6.4 - 5.4 = 1 (1)² = 1
N = 6 [tex]\sum (x-mean)^2[/tex] = 2.06
Since, Standard deviation = [tex]\sqrt{\frac{\sum (x-mean)^2}{N}}[/tex]
= [tex]\sqrt{\frac{2.06}{6} }[/tex]
= 0.5859
≈ 0.59
This is about the cone formula. If you don't know it, please don't answer. If you do, PLEASE ANSWER.
9514 1404 393
Answer:
(b) 10.5 in
Step-by-step explanation:
The formula for the volume of a cone is ...
V = 1/3πr²h . . . . . . for radius r and height h
Then the height is ...
h = 3V/(πr²)
Your cone has a volume V = 199 in³ and radius r = 4.25 in, so the height is ...
h = 3(199 in³)/(π(4.25 in)²) ≈ 10.52 in
The height of the cone is about 10.5 inches.

. A nationwide survey of college seniors by the University of Michigan revealed that almost 70% disapprove of daily pot smoking, according to a report in Parade. Suppose 12 seniors are selected at random and asked their opinion. Our goal is to investigate the number of pot smokers. (a) Verify that this is an example of a binomial experiment. (b) What is the probability that exactly one of the 12 seniors disapproves daily pot smoking
Answer:
a) Trials are independent, and there is a fixed number of trials, which means that the binomial probability distribution can be used.
b) 0.000015 = 0.0015% probability that exactly one of the 12 seniors disapproves daily pot smoking
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
a)
For each senior, there are only two possible outcomes. Either they disapprove daily pot smoking, or they do not. The seniors are selected at random, which means that the probability of one disapproving daily pot smoking is independent of other seniors, that is, the trials are independent. There is also a fixed number of trials.
b)
70% disapprove of daily pot smoking, according to a report in Parade, which means that [tex]p = 0.7[/tex]
12 seniors means that [tex]n = 12[/tex]
The probability is P(X = 1).
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 1) = C_{12,1}.(0.7)^{1}.(0.3)^{11} = 0.000015[/tex]
0.000015 = 0.0015% probability that exactly one of the 12 seniors disapproves daily pot smoking

Garrett has a current checking account balance of $695. Over the next three days, he receives a direct deposit of $475.75 from his job, pays an annual online banking fee of $24, and makes purchases of $34.21 and $8.92. He then withdraws $60 from an ATM that charges a $3.50 usage fee.
What is Garrett's account balance at the end of the day period? Write your answer in numeric form, such as $1369.05.
Answer:
1040.12
Step-by-step explanation:

A rectangular swimming pool is twice as long as it is wide. A paved border is 4 feet wide along the two longer sides and one of the shorter sides, and 8 feet wide along the other shorter side. The border and the pool have a combined area of 2046 square feet.
Let x represent the length of the shorter side of the swimming pool. Write an equation in standard form for the combined area of the pool and border in terms of x.

M-1/4=3/4 need to find m plz help
Answer:
M=1
Step-by-step explanation:
m-1/4=3/4 add 1/4 to both sides and you get m=1
Answer:
M = 1
Step-by-step explanation:
M-1/4=3/4
add 1/4 to both sides of the equation:
M - 1/4 + 1/4 = 3/4 + 1/4
simplify:
M = 1

Step-by-step explanation:
What is an equation of the line that passes through the point (4,-1) and has a slope of -2?
Answer:
Option C, [tex]y = -2x + 7[/tex]
Step-by-step explanation:
1) Slope-intercept format is represented by the formula [tex]y = mx + b[/tex]. By looking at the options, we can see that all of them follow this format.
So, first, we can identify which equations have a slope of -2 to narrow down our options. In slope-intercept form, the coefficient of the x-term, or [tex]m[/tex], represents the slope. So, this narrows the answer down to options b and c because they are the only ones that have [tex]m[/tex] as -2.
2) Next, in order to find which equation is the right answer, we can substitute the x and y values of the given point (4, -1) into both equations, then simplify. Whichever equation results in a true statement must be the answer. Let's try option c first. Substitute 4 for x and -1 for y:
[tex]-1=4(-2)+7\\-1 = -8+7\\-1=-1[/tex]
-1 does equal -1, so this statement is true. Thus, option c must be the answer.
The equation of the straight line will be -
y = -2x + 7
What is the general equation of a Straight line?
The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
We have an equation of the line that passes through the point (4,-1) and has a slope of -2.
Assume the equation of the line to be -
y = -2x + c
The line passes through the point (4,-1), so we can write -
-1 = -2 x 4 + c
-1 = -8 + c
c = -1 + 8
c = 7
Therefore, the equation of the straight line will be -
y = -2x + 7
