Answer:

Slope = -2

Y intercept = 4

Equation. y = -2x +5

Step-by-step explanation:

Using points, (1,2) and (3,-2)

Slope = (-2-2)/(3-1) = -4/2 = -2

Y intercept = 4

-2 = (y-3)/(x-1)

-2(x-1) = y-3

-2x +2 = y-3

y = -2x +2 +3

y = -2x +5

Rise over run, -2/1. The slope is -2

Y intercept is 4

Y =-2x + 4

Answer:

That would be 175% since in your question or the way you phrased it atleast, 100%=4, so 1 would be 25%, 25% times 3=75 so 175% =4+3=7

timf 3 số tự nhiên lẻ liên tiếp, biết tích của hai số lớn nhất lớn hơn 6 lần số bé nhất là 177 đơn vị
Murljashka [212]

Answer:

13, 15, 17

Step-by-step explanation:

Gọi 3 STN lẻ cần tìm là a, a+2, a+4 (a thuộc N*)

Theo đề bài ta có:

(a + 2)(a + 4) - 177 = 6a

=> a^2 + 4a + 2a + 8 = 6a + 177

=> a^2 + 6a + 8 = 6a + 177

=> a^2 + 6a - 6a = 177 - 8 (chuyển vế)

=> a^2 = 169 = 13^2

=> a = 13

=> a+2 = 15, a+4 = 17

Vậy 3 STN lẻ cần tìm là 13, 15, 17

Many people who bought Z-Game gaming systems over the holidays have complained that the systems they purchased were defective. I
Bas_tet [7]

Answer:

The upper limit for the 95% confidence interval for the population proportion of defective gaming systems is 0.022

Step-by-step explanation:

Upper Limit for 95% Confidence Interval can be calculated using p+ME where

  • p is the sample proportion of defective gaming systems (\frac{18}{1200} = 0.015)
  • ME is the margin of error from the mean

and margin of error (ME) around the mean can be found using the formula

ME=\frac{z*\sqrt{p*(1-p)}}{\sqrt{N} } where

  • z is the statistic of 95% confidence level (1.96)
  • p is the sample proportion (\frac{18}{1200}=0.015
  • N is the sample size (1200)

Using the numbers we get:

ME=\frac{1.96*\sqrt{0.015*0.985}}{\sqrt{1200} } ≈ 0.007

Then upper limit for the population proportion is 0.015+0.007 =0.022
