volume of cuboid = length × breadth ×height
step 1 : calculate the first one
v= 15cm ×8cm× 5cm = 1200cm^3
step 2 calculate the 2nd one
v= 15cm ×10cm×8cm = 600cm^3
number of bricks
1200cm^3 × 1bricks/ 600cm^3 = 2 bricks

D 2,685
Answers
9514 1404 393
Answer:
B. 2,022
Step-by-step explanation:
The student/faculty ratio tells you the total number of students in the school is ...
(15 students/teacher)×(179 teachers) = 2685 students
If 663 of those are first-year, then the number of upper-level students is ...
upper-level students = total students - first-year students
upper-level students = 2685 -663 = 2022
The total number of upper-level students is 2,022.

You want to examine the difference in the proportion of all UCF (1) and USF (2) students who prefer to use hand sanitizer.
1. Which test should be used to determine if a difference exists between the proportion of all UCF and USF students who prefer to use hand sanitizer?
a. z test for means t test for means.
b. z test for proportions paired.
c. z test for means.
d. paired t test for means.
2. Which alternative hypothesis should be used to determine if a difference exists between the proportion of all UCF and USF students who prefer to use hand sanitizer?
A. HA : mu1 - mu2 < 0.
B. HA : mu1 - mu2 is not equal to 0.
C. HA : mu1 - mu2 > 0.
D. HA : p1 - p2 < 0.
E. HA : p1 -p2 > 0.
Answers
Answer:
1. a. z test for means and t test for means.
2. C. HA : mu1 - mu2 > 0
Step-by-step explanation:
Hypothesis testing is used in a situation where there are more than 1 alternative available. The t test is conducted in the mean which determines the t value and then this value is compared with p value to identify the situation whether to accept or reject the null hypothesis. The alternative hypothesis in this situation is is represented by mu.

Write the equation of the line that passes through the points (2,5) and (3, 10)
Answers
Answer:
y = 5x-5
Step-by-step explanation:
First find the slope
m = ( y2-y1)/(x2-x1)
= ( 10-5)/(3-2)
= 5/1
=5
Using slope intercept form
y = mx+b
y = 5x+b
Substituting a point into the equation
5 = 5*2+b
5 = 10+b
Solving for b
5-10 = b
-5 =b
y = 5x-5

the total cost of 2 kg of Apples in 6 of oranges is rupees 570 if the cost of 3 kg of apples is the same as the cost of 5 kg of oranges find the rate of cost of apples and oranges
Answers
Answer:
Cost of 1 kg apple = a = RS 102 (Approx.)
Cost of 1 kg orange = b = RS 61 (Approx.)
Step-by-step explanation:
Assume;
Cost of 1 kg apple = a
Cost of 1 kg orange = b
So,
2a + 6b = 570 ....... Eq1
and
3a = 5b..........Eq2
From eq 2
3a = 5b
a = 5b / 3
So,
2a + 6b = 570
2(5b/3) + 6b = 570
b = 61.07
Cost of 1 kg orange = b = RS 61 (Approx.)
a = 5b / 3
a = 5(61) / 3
Cost of 1 kg apple = a = RS 102 (Approx.)
