Answer:

1. Simplify the inequality 5.1(3 + 2.2x) > -14.25 - 6(1.7x + 4):

15.3+11.22x>-14.25-10.2x-24 10;15.3+11.22x>-10.2x-38.75.

2. Separate terms with x and without x in different sides:

11.22x+10.2x>-38.75-15.3.

3. Add similar terms:

21.42x>-54.05.

4. Divide by 21.42:

x>-54.05/21.42

x>-2.5

I am better at substitution, but you want to get the equations as similar as possible, but are the opposite, so you can cancel it out.

A cone and its dimensions are shown in the diagram. What is the volume of the cone in cubic inches

aliya0001 [1]

Answer:1

V = 62.1262 cubic inches

Step-by-step explanation:

The formula for volume of a cone is V = (1/3)πr²h where r is the radius of the base, and h is the height.

We are given the height, h = 7 1/2 inches, or 15/2 inches

We are given the diameter of the base of 5 5/8 inches, or 45/8 inches

The radius is half the diameter, so divide 45/8 by 2. The radius is 45/16.

Plug these values into the formula and find V

V = (1/3)π(45/16)²(15/2)

V = 30,375π/1,536 = 62.12622191

rounding to 4 decimal places gives us 62.1262 cubic inches

Answer:

The correct answer is "0.3410, 0.4990".

Step-by-step explanation:

Given values are:

$n=150$

$p=\frac{63}{150}$

$=0.42$

At 95% confidence interval,

C = 95%

z = 1.96

As we know,

⇒ $E=z\sqrt{\frac{p(1-p)}{n} }$

By substituting the values, we get

$=1.96\sqrt{\frac{0.42\times 0.58}{150} }$

$=1.96\sqrt{\frac{0.2436}{150} }$

$=0.0790$

hence,

The confidence interval will be:

= $p \pm E$

= $0.42 \pm 0.079$

= $(0.3410,0.4990)$
