1. Simplify -7 + {12 - 3[50 - 4(2+3)] }

Komok [63]

1. Simplify $-7 + (12 - 3[50 - 4(2+3)])$ this expression step by step:

$2+3=5;$
$4\cdot (2+3)=4\cdot 5=20;$
$50-4\cdot (2+3)=50-20=30;$
$3\cdot [50-4(2+3)]=3\cdot 30=90;$
$12-3\cdot[50-4(2+3)]=12-90=-78;$
$-7 + (12 - 3[50 - 4(2+3)])=-7+(-78)=-7-78=-85.$

2. Simplify the expression $\dfrac{1}{3} + 6\left(\dfrac{2}{3} - \dfrac{1}{6}\right)^2$ in the same way:

$\dfrac{2}{3}-\dfrac{1}{6}=\dfrac{2\cdot 2-1}{6}=\dfrac{3}{6}=\dfrac{1}{2}$
$\left(\dfrac{2}{3} - \dfrac{1}{6}\right)^2=\left(\dfrac{1}{2} \right)^2=\dfrac{1}{4}$
$\dfrac{1}{3} + 6\left(\dfrac{2}{3} - \dfrac{1}{6}\right)^2=\dfrac{1}{3} + 6\cdot \dfrac{1}{4}=\dfrac{1}{3}+\dfrac{3}{2}=\dfrac{1\cdot 2+3\cdot 3}{6}=\dfrac{11}{6}$

Write a decimal that represents 8×100+4×1+5×1√100+3×1√1000 help please

Alborosie

The rules for converting fractions with denominators 10, 100, 1000, etc. into decimal fraction:

(i) Count the number of zeroes coming after 1 in the denominator.

(ii) Count an equal number of places in the numerator starting from the unit digit then place the decimal point to the left of the digit reached.

Let us consider some of the following examples;

If a wheel has a diameter of 15 centimeters what is the area of the wheel nearest centimeter

maw [93]

Answer:

<h2>A = 177 cm²</h2>

Step-by-step explanation:

A diameter is two times longer than a radius. Therefore, if the diameter

d = 15cm, then the radius r = (15cm) : 2 = 7.5cm.

The formula of an area of a circle:

$A=\pi r^2$

Substitute:

$A=\pi(7.5)^2=56.25\pi\ cm^2$

$\pi\approx3.14$

Then

$A\approx(56.25)(3.14)\approx177\ cm^2$

For a sample size of 115 and a population parameter of 0.1,what is the standard deviation of the normal curve that can be used t

Helga [31]

Answer:

A) 0.028

Step-by-step explanation:

Given:

Sample size, n = 115

Population parameter, p = 0.1

The X-Bin(n=155, p=0.1)

Required:

Find the standard deviation of the normal curve that can be used to approximate the binomial probability histogram.

To find the standard deviation, use the formula below:

$\sigma = \sqrt{\frac{p(1-p)}{n}}$

Substitute figures in the equation:

$\sigma = \sqrt{\frac{0.1(1 - 0.1)}{115}}$

$\sigma = \sqrt{\frac{0.1 * 0.9}{115}}$

$\sigma = \sqrt{\frac{0.09}{115}}$

$\sigma = \sqrt{7.826*10^-^4}$

$\sigma = 0.028$

The Standard deviation of the normal curve that can be used to approximate the binomial probability histogram is 0.028
