(X)+(X+1)=24
"consecutive" means right after the other, so, if the first one is (X), the second integer <u>must be</u> (X+1). The answer 24 is given so you just have to solve the equation.
2X+1=24
2X=23
X=11.5
Answer:
60
Step-by-step explanation:
First, find the area of the square as it the missing piece wasn't missing.
8 x 9 = 72
Then, find the area of the missing section.
3 x 4 = 12
Finally, subtract 12 from 72 and you get 60
Answer:
24
Step-by-step explanation:
what is the smallest number which is a multiple of both 8 and 12? so, an multiple of 8 must have 2 as a factor at least 3 times. Similarly, multiples of 12 have at least two 2's and one 3. so we need 2x2x2x3 or 24 if every factor is to be included.
I'm not the best at explaining but you can search google to get the better Idea.
(btw this is for the fist question)
To solve this, we use the z test.
The formula:
z = (x – u) / s
where x is sample value = 20, u is the mean = 15, and s is
the standard deviation = 2.5
z = (20 – 15) / 2.5
z = 2
Since we are looking for values greater than 20, this is
right tailed test. We use the standard distribution tables to find for P.
P = 0.0228
Therefore:
number of students = 100 * 0.0228 = 2.28
<span>2 to 3 students will get greater than 20 measurement</span>
The total cost of the tent is 409.86

explanation:
230×0.65=149.50
230+149.50=379.50×.08=30.36
379.50+30.36=409.86
(Hope this helps :) )
