15y - 9 < 36
15y - 9 + 9 < 36 + 9
15y < 45
15y ÷ 15 < 45 ÷ 15
y < 3

Answer:
12 bats
Step-by-step explanation:
Let us number the bat caves from 1 to 45 and divide them into 5 parts:
a) 1
b) 2 to 29 (
bats)
c) 30
d) 31 to 44 (
bats)
e) 45
It is given that any 7 caves in a row has 77 bats. Hence, the total number of bats in part b and d = 
bats.
There remains 
bats in cave number 1, 30 and 45.
Now, our question demands the maximum possible number of bats in cave 30.
Minimum number of bats in a cave is 2. So we shall put 2 bats in the last cave, which gives us bats in the first cave.
Therefore, the number of bats in cave number 30 = 
bats.
The answer is -8. hope i helped
Answer:
b. 2-independent sample t-test
Correct for this case is the best test since the result from each group are independent and we can compare the sample means between th two groups
Step-by-step explanation:
For this case the intention is try to test if scores on a test of science achievement differ for female and male 8th grade students. let's analyze the possible options for this case:
a. 2-dependent sample t-test
False is not possible since the nature of the gender is not possible to conclude tha the results from boys and girls are dependent
b. 2-independent sample t-test
Correct for this case is the best test since the result from each group are independent and we can compare the sample means between the two groups
c. Correlation
False we can't compare the means of interest with a correlation coefficient since that's not the purpose of the study
d. 2-way ANOVA
False we have just one variable between two groups so is not possible to apply a 2 way ANOVA
Answer:
The answer to your question is Area = 3240 ft² or Area = 360 yd²
Step-by-step explanation:
Data
length = 30 yd
width = 36 ft
Area = ? ft²
Area = ? yd²
Process
1.- Convert the units
1 yd --------------------- 3ft
30 yd ------------------ x
x = (30 x 3)/1
x = 90 ft
1 yd ------------------- 3 ft
x ------------------- 36 ft
x = (36 x 1) / 3
x = 12 yd
2.- Calculate the area of the rectangle in ft²
Area = length x width
-Substitution
Area = 90 x 36
= 3240 ft²
3.- Calculate the area in yd²
Area = 30 x 12
= 360 yd²
