John's family visited his grandmother over the weekend. The drive to her house took 2 hours at their usual speed. The trip took 15 minutes longer because traffic was bad and they had to drive 5 mph slower. How many miles away is Johns grandmother's house?
Answers
Let the normal speed = x mph
The way to his grandmothers they drove 2x miles
Return trip was 2.25(x-5)
Set those equal and solve for x:
2x = 2.25(x-5)
Simplify:
2x = 2.25x -11.25
Subtract 2.25x from both sides:
-0.25x = -11.25
Divide both sides by-0.25:
X = 45
The usual speed is 45 mph.
So now 2 hours at 45 mph = 90 miles to his grandmothers house
Answer:
90 miles

What is rounding off?Rounding numbers refers to changing a number's digits such that it approximates a value. The provided number is more simply represented by this value. For instance, 700,000 rather than 698,869 could be used to express a town's population.
Given that;
Correct the number 33.246 to 2 significant figures.
Now, we can check the first non-zero digit if rounding to one significant figure. look at the digit after the first non-zero digit if rounding to two significant figures.
Thus, The value of number after 2 significant figures is,
⇒ 33

x = 3 and y = 7
Step-by-step explanation:
2x + y = 13
+ x - y = -4 (adding both equations)
3x - 0y = 9
3x = 9
x = 9/3
x = 3
now substituting
x - y = -4
3 - y = -4
- y = -4 - 3
- y = -7
y = 7 (the negative sign on both sides get canceled)
Therefore,
x = 3 and y = 7

A medical device company knows that 11% of patients experience injection-site reactions with the current needle. If 4 people receive injections with this type of needle, what is the probability that none of the 4 people get an injection-site reaction? 0.0001 0.3726 0.4400 0.6274
Answers
Answer: 0.6274
Step-by-step explanation:
Given: The proportion of patients experience injection-site reactions with the current needle : p=0.11
Sample size : n= 4
Let x be a binomial random variable that represents the people get an injection-site reaction.
Binomial probability formula: [tex]P(X=x)= ^nC_x p^x(1-p)^{n-x}[/tex]
The required probability : P(x=0)
[tex]=\ ^4C_0(0.11)^0(1-0.11)^4\\\\=(1)(1)(0.89)^4\\\\=0.62742241\\\approx0.6274[/tex]
Hence, the probability that none of the 4 people get an injection-site reaction = 0.6274
The probability that none of the 4 people get an injection-site reaction would be 0.6274.
How to find that a given condition can be modelled by binomial distribution?Binomial distributions consists of n independent Bernoulli trials.
Bernoulli trials are those trials which end up randomly either on success (with probability p) or on failures( with probability 1- p = q (say))
Suppose we have random variable X pertaining to binomial distribution with parameters n and p, then it is written as
[tex]X \sim B(n,p)[/tex]
The probability that out of n trials, there'd be x successes is given by
[tex]P(X =x) = \: ^nC_xp^x(1-p)^{n-x}[/tex]
A medical device company knows that 11% of patients experience injection-site reactions with the current needle.
If 4 people receive injections with this type of needle.
The proportion of patients who experience injection-site reactions with the current needle
p=0.11
Sample size : n= 4
Let a binomial random variable be x that represents the people who get an injection-site reaction.
Binomial probability formula:
P(X = x) = [tex]^nC_x p^x(1-p)^{n-x}[/tex]
The required probability :
P(x=0)
[tex]=\ ^4C_0(0.11)^0(1-0.11)^4\\\\=(1)(1)(0.89)^4\\\\=0.62742241\\\\\approx0.6274[/tex]
Hence, the probability that none of the 4 people get an injection-site reaction would be 0.6274.

Which ratios are equal to 64 when the scale factor is 8? Select all that apply.
Group of answer choices
The scaled volume of a cube to the original volume.
The scaled surface area of a square pyramid to the original surface area.
The scaled volume of a rectangular prism to the original volume.
The scaled perimeter of an octagon to the original perimeter.
The scaled area of a triangle to the original area.
Answers
Answer:
The scaled surface area of a square pyramid to the original surface area.
The scaled area of a triangle to the original area.
Step-by-step explanation:
Suppose that we have a cube with sidelength M.
if we rescale this measure with a scale factor 8, we get 8*M
Now, if previously the area of one side was of order M^2, with the rescaled measure the area will be something like (8*M)^2 = 64*M^2
This means that the ratio of the surfaces/areas will be 64.
(and will be the same for a pyramid, a rectangle, etc)
Then the correct options will be the ones related to surfaces, that are:
The scaled surface area of a square pyramid to the original surface area.
The scaled area of a triangle to the original area.

An investment website can tell what devices are used to access the site. The site managers wonder whether they should enhance the facilities for trading via "smart phones" therefore they want to estimate the proportion of users who access the site that way. They draw a random sample of 200 investors from their customers. Suppose that the true proportion of smart phone users in 36%. What is the probability that the sample proportion is between 0.30 and 0.40? Hint: You'll need to find one z-score for 0.30 and another for 0.40. Then find the area between the two z-scores.
Answers
Answer:
0.8418
Step-by-step explanation:
We have p = 0.36
Sample size = 200
We have to find the standard error of proportion
= √p(1-p)/n
= √0.36(1-0.36)/200
= 0.034
P(0.30<p^0.40)
= 0.30-0.36/0.034 = -1.76,
0.40-0.36/0.034 = 1.18
P(-1.76<z<1.18)
When we go to the standard normal distribution table
P(z<1.18) = 0.8810
P(z<-1.76) = 0.0392
0.8810 - 0.0392
= 0.8418
This is the probability of the sample proportion being between 0.30 and 0.40
