Answer:

The slope is 3/4

Please correct me if I am wrong please and thank you

Step-by-step explanation:

I use the slope formula \frac{y2-y1}{x2-x1}

Plug in (2,1) and (-2,-2)

1-(-2)/2-2

= 3/4

Answer:

3/4

Step-by-step explanation:

The slope of this line is 3/4. Slope is the rise over run or the change in y over the change in x. So one way to find the slope is to count how much y and x changes, in this graph between the 2 points y increases by 3 and x increases by 4. So the final slope is 3/4, (if one value decreases then the slope is negative). One way to visually check the slope is to remember that slopes less than -1 or greater than 1 make the line steeper while fraction slopes make the line flatter. Also, you can use the slope formula, \frac{y_{2-y_{1} } }{x_{2}-x_{1}  } just plug in the values.

Step-by-step explanation:

35 + 35 = 70

180 - 70 = 110

180 - 110 = 70

70  + 70 = 140

180 - 140 = 40

so the answer is 40

Answer: a) BC = 1386.8 ft

b) CD = 565.8 ft

Step-by-step explanation:

Looking at the triangle,

AD = BD + 7600

BD = AD - 7600

Considering triangle BCD, we would apply the the tangent trigonometric ratio.

Tan θ = opposite side/adjacent side. Therefore,

Tan 24 = CD/BD = CD/(AD - 700)

0.445 = CD/(AD - 700)

CD = 0.445(AD - 700)

CD = 0.445AD - 311.5 - - - - - - - -1

Considering triangle ADC,

Tan 16 = CD/AD

CD = ADtan16 = 0.287AD

Substituting CD = 0.287AD into equation 1, it becomes

CD = 0.445AD - 311.5

0.287AD = 0.445AD - 311.5

0.445AD - 0.287AD = 311.5

0.158AD = 311.5

AD = 311.5/0.158

AD = 1971.52

CD = 0.287AD = 0.287 × 1971.52

CD = 565.8 ft

To determine BC, we would apply the Sine trigonometric ratio which is expressed as

Sin θ = opposite side/hypotenuse

Sin 24 = CD/BC

BC = CD/Sin24 = 565.8/0.408

BC = 1386.8 ft

At 95% confidence interval, true population mean is given by

x+/- 2sd

where x= sample mean and sd = sample standard deviation
True mean of population = 13.50 +/- 2*1.51 = 13.50+/-3.02

Interval: 13.50+3.02, 13.50-3.02 = 16.51, 10.48

vladimir2022 [97]

Answer:

I would reject the null hypothesis.

Step-by-step explanation:

The test is a two-tailed test because it is stated that the alternate hypothesis is two-sided.

Degree of freedom = n - 1 = 350 - 1 = 349

At 349 degrees of freedom and 5% significance level, the critical values are -1.96702 and 1.96702

Conclusion:

Reject the null hypothesis because the test statistic 3 falls outside the region bounded by the critical values -1.96702 and 1.96702.
