Answer:
He decorates 5 flower pots
Step-by-step explanation:
60 / 12 = 5
Answer:
15
Step-by-step explanation:
9.30am-10.30am is 1h
1h=60min
60min/12min= 5
he has done 5 pots until his break,
after his break,
10.30am +20min = 10.50am
10.50am-12.50pm is 2h
2h=120min
120min/12min=10
10+5=15
He has done 15 pots

Because 3 and 5 are prime numbers (5 can only be divided by 1 and 5, and 3 can only be divided by 1 and 3), this is the most simplified form.
Accidents on highways are one of the main causes of death or injury in developing countries and the weather conditions have an impact on the rates of death and injury. 25% of accidents in foggy conditions result in death, 12.5% of accidents in rainy conditions result in death, and 5% of accidents in sunny conditions result in death. Sunny conditions occur 60% of the time, while rainy and foggy conditions each occur 20% of the time. What is the probability that and accident results in a death?
Answer:
0.105 = 10.5% probability that an accident results in a death.
Step-by-step explanation:
What is the probability that an accident results in a death?
5% of 60%(sunny)
25% of 20%(foggy)
12.5% of 20%(rainy)
So
[tex]p = 0.05*0.6 + 0.25*0.2 + 0.125*0.2 = 0.105[/tex]
0.105 = 10.5% probability that an accident results in a death.
The probability that an accident results in a death is 0.105 = 10.5%
Given :
25% of accidents in foggy conditions result in death.
12.5% of accidents in rainy conditions result in death
5% of accidents in sunny conditions result in death
"Probability"
The probability that an accident results in a death
5% of 60%(sunny)25% of 20%(foggy)12.5% of 20%(rainy)Probability =0.05*0.6+0.25*0.2+0.125*0.2
Probability =0.105
Probability =10.5%
The probability that an accident results in a death is 10.5%.

Keith paid 8.44 each for 5 lizard toys and got 5 cages for 8.45 each with 5 20 bills . How much change did Keith recive
Answer:
19.51
Step-by-step explanation:
Answer:
15.55
Step-by-step explanation:
First, find the total cost of the items
8.44 * 5= 42.20
8.45 * 5= 42.25
42.20 + 42.25= 84.45
Then the amount of money given
20 * 5= 100
Last, subtract the cost from the amount given
100 - 84.45 =15.55
The human resources department of an engineering company gives IQ tests to a randomly selected group of new hires every year. They claimed that the mean IQ score of new hires, , from this year is greater than or equal to the mean IQ score of new hires, , from last year. This year, 95 new hires took the test and scored an average of 112.2 points with a standard deviation of 14.0 . Last year, 70 new hires took the IQ test and they scored an average of 117.8 points with a standard deviation of 14.5 . Assume that the population standard deviation of the IQ scores from the current year and the last year can be estimated by the sample standard deviations, since the samples that are used to compute them are quite large. Is there enough evidence to reject the claim of the human resources department, at the 0.01 level of significance

Answer:
x = 9
Step-by-step explanation:
If g(x) = 3, that means that the output is three.
Outputs are y values.
Look at the graph. When y=3, the x = 9.
So the input value for which g(x) = 3 (aka that gives the output y = 3) is x = 9

The solution is, y = 2 ^ (x + 2) +3, is the function is shown in the graph below.
What is graph?In mathematics, the graph of a function f is the set of ordered pairs, where {\displaystyle f(x)=y.} In the common case where x and f(x) are real numbers, these pairs are Cartesian coordinates of points in two-dimensional space and thus form a subset of this plane.
here, we have,
For this case we observe the cut point with the y axis in:
(0, 7)
The function that complies with this is:
y = 2 ^ (x + 2) +3
We have then:
y = 2 ^ (0 + 2) +3
y = 2 ^ (2) +3
y = 4 + 3
y = 7
Answer:
The answer for this case is given by:
y = 2 ^ (x + 2) +3
option 2
Hence, The solution is, y = 2 ^ (x + 2) +3, is the function is shown in the graph below.

Brian jogged 2 miles in 30 minutes. At this rate, how many miles will he jog in 2 hours?
4 miles
8 miles
6 miles
10 miles
Answer:
8miles
Step-by-step explanation:
If Brian jogged 2 miles in 30 minutes, this is expressed as;
2miles = 30minutes
To calculate the distance covered in 2hrs, we can say
x miles = 2hrs (120minutes)
Divide both expressions
2/x = 30/120
Cross multiply
30x = 2 * 120
30x = 240
x = 240/30
x = 8
hence he covers 8miles in 2hrs

EXAMPLE How many inches are in 6 miles? (1 mile=5280 feet, 1 foot=12 inches)
Prove that if a^x=b^y=ab^xy then x+y=1
Answer:
Below.
Step-by-step explanation:
Prove that if
a^x = b^y = (ab)^(xy) then x + y = 1.
From the second equation:
y = 1 - x
So we have:
a^x = b^y = b^(1-x)
Taking logs:
x ln a = (1-x)ln b
x ln a + x ln b = ln b
x = ln b / ( ln a + ln b)
x = ln b / ln ab.
This is true if x + y = 1.
Now consider b^y = (ab)^(xy):
b^(1 - x) = (ab)^(x(1- x)
ln b - x ln b = x(1 - x)ln ab
ln b - x ln b = x ln ab - x^2 ln ab
Now we substitute for x = ln b / ln ab in this expression.
If left side = right side then we have proved this identity and therefore the original one.
Left side = ln b - (ln b / ln ab) * ln b = ln b - (ln b)^2 / ln ab.
Right side = (ln b / ln ab) * ln ab - [(ln b)^2 / (ln ab)^2] * ln ab
= ln b - (ln b)^2 / ln ab.
Left side = right side so this identity is true, and so the original one
( x + y = 1) is true also.
