Answer:
2 2/3 - 1 3/4 = 11/12
Step-by-step explanation:
You could convert them both to improper fractions then you would make them have common denominators so the least common denominator for the would be 12 so you would multiply them and then you would subtract them to get your answer of 11/12.
2 2/3 = 8/3 times 4 = 32/12
1 3/4 = 7/4 times 3 = 21/12
32/12 - 21/12 = 11/12
. 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

If Colorado spring, Colorado, has 1.2 times as many days of sunshine as Boston, Massachusetts, how many days of sunshine does each city have if there are a total of 464 days of sunshine between the two in a year? ( Round your answer to the nearest day.)
Boston has 211 days of sunshine and Colorado Springs has 253 days of sunshine.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Let us consider x to represent the number of days of sunshine in Boston.
We know that Colorado Springs has 1.2 times as many days of sunshine as Boston.
The total number of days of sunshine between the two cities is 464.
Set up an equation to solve x.
x + 1.2x = 464
Simplifying and solving for x, we get:
2.2x = 464
x = 211. So Boston has 211 days of sunshine.
The number of days of sunshine in Colorado Springs, we can multiply by 1.2:
1.2x = 1.2(211) = 253.2
So Colorado Springs has 253 days of sunshine.
Therefore, Boston has 211 days of sunshine and Colorado Springs has 253 days of sunshine.

Seventy homes that were for sale in Tampa, Florida in Spring of 2019 were randomly selected. A regression model to predict house price was run based on first floor square footage and the indicator variable for Beach (1 if the house was within 1 mile of the beach, 0 if not). There was also an interaction term for firstfloorsquarefootage*Beach.
Term Estimate Std. Error
Intercept -93.4 214.5
Beach 782.5 31.45
firstfloorsquarefootage 0.412 0.120
firstfloorsquarefootage*Beach 0.004 0.012
How would you interpret the slope coefficient for firstfloorsquarefootage*Beach?
A. Homes near the Beach are less expensive than elsewhere for a given size.
B. The slope of the relationship between firstfloorsquarefootage and price is lesssteep for homes near the beach than elsewhere in Tampa
C. Homes near the Beach are more expensive than elsewhere for a given size.
D. The slope of the relationship between firstfloorsquarefootage and price is moresteep for homes near the beach than elsewhere in Tampa
Answer:
D.The slope of the relationship between first floor square footage and price is more steep for homes near the beach than elsewhere in Tampa
Step-by-step explanation:
We can see from the output that was run in this regression that this variable has a positive coefficient. So the result is going to be interpreted to show an increase. Therefore d is the answer as it shows that these homes which are closer to the beach are steeper compared to those that are in other areas of tampa. It's necessary to always look out for the signs of the coefficient when interpreting a regression result
Sue has $100 saved to buy concert tickets that go on sale in 8 weeks. She plans to save $15 every 2 weeks. Will Sue have enough money saved to buy 4 concert tickets that cost $50 each?
Answer:
she wont have enough money.
Step-by-step explanation:
she is saving money every 2 weeks. 8 divided by 2 is 4, so we'd have 15 x 4 which is 60. then we'd add it to 100, which would be 160, then divide it by 4, which would roughly come down to 40 dollars each, meaning we would not have enough money for 4 tickets
Answer:
she does not have enough she will need 40 dollars more

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
