Answer:

Using the t-distribution, the 99% confidence interval for the true average number of alcoholic drinks all UF female students (over 21) have in a one week period is (3.25, 4.85).

We have the standard deviation for the sample, thus, the t-distribution is used to solve this question.

First, we find the number of degrees of freedom, which is the sample size subtracted by 1, thus:

Then, using a calculator, with  and 169 df, we have that the two-tailed critical value is .

The margin of error is:

In this problem, , then:

The confidence interval is:

In this problem, , then:

The confidence interval is (3.25, 4.85).

Answer:

Rm267.58

Step-by-step explanation:

Firstly, 15/100 × 370 = Rm55.20.Then,Rm370-Rm55.20 = Rm314.80. After that, 15/100 × 314.80 = Rm47.20. Then, Rm314.80 - Rm47.22 = Rm267.58.

Answer:

12x³ meters

Step-by-step explanation:

Area/Width = Length

Length = 144x⁴/12x

= 12x³

Answer:

12x^3

Step-by-step explanation:

To find the length, you divide the height and the area, and you get your answer. So therefore, 144x^4 divided by 12x = 12x^3.

The answers are (9+12)÷(3+4)÷(2+1)·2 = 2, (9+12÷3)+(4÷2+1·2) = 8, (9+12)÷3+(4÷2)+(1·2) = 11 and (9+12)÷(3+4)÷(2+1·2) = 12.

An expression in math is a sentence with a minimum of two numbers or variables and at least one math operation. This math operation can be addition, subtraction, multiplication, or division.

Given are the expressions, we need to put the parentheses to equate the values,

1) 9+12÷3+4÷2+1·2 = 2,

9+12 = 21, 3+4 = 7, 1+2 = 3

(9+12)÷(3+4)÷(2+1)·2 = 21 ÷ 7 ÷ 3 · 2 = 2

(9+12)÷(3+4)÷(2+1)·2 = 2

2) 9+12÷3+4÷2+1·2 = 8

(9+12) = 21, (2+1·2) = 6

(9+12÷3)+(4÷2+1·2) = 21 ÷ 3 + 1 = 8

(9+12÷3)+(4÷2+1·2) = 8

3) 9+12÷3+4÷2+1·2 = 11

9+12 = 21, 4÷2 = 2, 1·2 = 2

(9+12)÷3+(4÷2)+(1·2) = 21 ÷ 3 + 2 +2 = 7 + 2 + 2 = 11

(9+12)÷3+(4÷2)+(1·2) = 11

4)  9+12÷3+4÷2+1·2 = 12

(9+12)÷(3+4)÷(2+1·2) = 12

Hence, the answers are (9+12)÷(3+4)÷(2+1)·2 = 2, (9+12÷3)+(4÷2+1·2) = 8, (9+12)÷3+(4÷2)+(1·2) = 11 and (9+12)÷(3+4)÷(2+1·2) = 12.

Answer:

1044cm²

Step-by-step explanation:

first split the polygon into two shapes

46-21=25

so the length of a shape is 25

so 30x25=750

then 21*14=294

then 750+294=1044cm²

Answer:

1044 cm²

Step-by-step explanation:

Subdivide the polygon into two rectangles by drawing a vertical line from the interior vertex of the L-shape.

Area of a rectangle = width x length

⇒ area of largest rectangle (left) = (46 - 21) x 30 = 750 cm²

⇒ area of smallest rectangle (right) = 14 x 21 = 294 cm²

Total area of shape = 750 + 294 = 1044 cm²
