Answer: 45 / 40 ft

Step-by-step explanation:

Given that She decides to change the width, the shorter side of the courtyard, from 45 ft to 40 ft. Which expression finds the change in the scale factor?

Actual width of shorter side = 45 ft

New width of shorter side = 40 ft

Scale factor is the ratio of the actual length to the new or intended length

Scale factor = Actual width / New width

Hence, scale factor :

45 ft / 40 ft

What is the sequence rule for : 1.8, 2.58, 3.90, 4.95, 6
slamgirl [31]
I believe there is a typo in the problem. It should be:<span>1.8, 2.85, 3.90, 4.95, 6
If that was the case, the answer will be easy.

In this sequence, the rule is start at 1.80 then keep add 1.05. You can try to put them all into the equation

</span>1.80 + 1.05= 2.85
2.85+ 1.05= 3.90
3.90+ 1.05= 4.95
4.95+ 1.05= 6.00

The following data were given in a study of a group of 1000 subscribers to a certain magazine. In reference to job, marital stat
kozerog [31]

Answer:

(a)  P(M\ or\ P\ or\ C) = 1.307

(b) See Explanation

Step-by-step explanation:

Given

P = 312 ---- Professionals,

M = 470 ----- Married persons,

C = 525 ---- College graduates,

PCG = 42  ----- Professional college graduates,

MCG = 147 ----- Married college graduates,

MP = 86  ---- Married professionals,

MPCG = 25 ---- Married professional college graduates

Total =1000

Solving (a): P(M or P or C)

This is calculated as:

P(M\ or\ P\ or\ C) = P(M) + P(P) + P(C)

P(M\ or\ P\ or\ C) = \frac{n(M) + n(P) + n(C)}{Total}

P(M\ or\ P\ or\ C) = \frac{470 + 525 + 312}{1000}

P(M\ or\ P\ or\ C) = \frac{1307}{1000}

P(M\ or\ P\ or\ C) = 1.307

(b) In probabilities, the probability of an event or collection of events must not exceed 1 and must not go below 0.

In (a) above, the calculated probability exceeds 1.

Because of this single reason, the collected data is incorrect

Give the equation of the line that is parallel to y=-3x+1 and goes through (-5,-6)
stich3 [128]

Hi there! The answer is y = -3x - 21

Let's set up the equation of the line step by step! First we need to know that we need to set up an equation in slope-intercept form. We get the following:

y = ax + b.
a represents the slope of the line.
b represents the intercept with the y-axis.

Since our new line is parallel to y = -3x + 1, both lines have the same slope. Therefore the slope of our line, which is represented by a, is -3.

y = -3x + b.
We also know that this line goes through the point (-5, -6) and therefore we can plug in these coordinates into our formula.

-6 = -3 × -5 + b
Simplify

-6 = 15 + b
Subtract 15

-21 = b
Switch sides

b = -21
Hence, y = -3x - 21

~ Hope this helps you!
