$Question$

Liz wants to find the quotient of 63 and 0.15. what is the first step she should take?

Answer:

→(Well First 63 ÷ 0.15 = 420) ←

A: divide 63 and 0.15 by 10 Would be my Answer

To add two decimal numbers, first check if they have the same number of digits to the right of the decimal point. If they don't, add zeros to the right of one of the numbers until they do. Then, write one number on top of the other, lining up the decimal points vertically.

x is number of years after 1997.

To calculate number of laptops in 2005:
x=2005-1997
x=8

t=20*8+31
t=160+31
t=191

In year 2005 school had 191 laptops.

Bradford Electric Illuminating Company is studying the relationship between kilowatt-hours (thousands) used and the number of ro

For the regression equation and e the number of kilowatt-hours, in thousands, for a six-room house is mathematically given as

Y = 1.33-0.667X and 5.3332

<h3>What is the number of kilowatt-hours, in thousands, for a six-room house?</h3>

Generally, the equation for the standard deviation is mathematically given as

$s$ ₓ = $\sqrt{\frac{\sum\(X-\=X)^2}{n-1} }$

= $\sqrt{\frac{66.9}{10-1} }$

= 2.72

$s_y$ = $\sqrt{\frac{36.4}{10-1} }$

= 2.01

therefore correlation coff

r = $\frac{44.6}{(10-1)(2.72)(2.01)}$

r = 0.9038

In conclusion the regression equation is given

b = r_sy/sx

b = (0.9038)(2.01/2.72)

= 0.667

intercept

a = 7.4-0.667(9.1)

a = 1.33

The regression equation is

Y = 1.33-0.667X

(b) number of kilowatts x = 6 house

Y = 1.33-0.667X

Y = 1.33-0.667(6)

= 5.3332

Which of the following represent the values of x, y, and z.

Paraphin [41]

Answer:

Part 1) $z=4\sqrt{3}\ units$

Part 2) $y=4\sqrt{2}\ units$

Part 3) $x=4\sqrt{6}\ units$

Step-by-step explanation:

see the attached figure with letters to better understand the problem

step 1

<em>Find the value of z</em>

In the right triangle DBC

$cos(C)=\frac{4}{z}$ ----> equation A

In the right triangle ABC

$cos(C)=\frac{z}{12}$ ----> equation B

equate equation A and equation B

$\frac{4}{z}=\frac{z}{12}$

$z^{2}=48$

$z=4\sqrt{3}\ units$

step 2

In the right triangle DBC

Applying the Pythagoras Theorem

$z^{2}=y^{2}+4^{2}$

we have

$z=4\sqrt{3}\ units$

substitute

$(4\sqrt{3})^{2}=y^{2}+4^{2}$

$48=y^{2}+16$

$y^{2}=48-16$

$y^{2}=32$

$y=4\sqrt{2}\ units$

step 3

Find the value of x

In the right triangle ABC

Applying the Pythagoras Theorem

$12^{2}=x^{2}+z^{2}$

we have

$z=4\sqrt{3}\ units$

substitute

$12^{2}=x^{2}+(4\sqrt{3})^{2}$

$144=x^{2}+48$

$x^{2}=144-48$

$x^{2}=96$

$x=4\sqrt{6}\ units$
