Answer:
The equation of the line is y=1.4x+6.8
Step-by-step explanation:
Given 2 points on the graph, you can find the slope using the equation: . The 2 points are (-7, -3) and (-2, 4). X1 is -7, X2 is -2, Y1 is -3, Y2 is 4. The slope would be 1.4 once you plug in the numbers to the equation to finding the slope. Once you find the slope, use one of the points to find the y-intercept along with the slope you found and the y-intercept will be 6.8.
Answer:
Remember The distance, speed, time triangle
Step-by-step explanation:
Formula is
Speed x time=distance
Distance divided by speed=time
distance divided by time=speed
Answer:
The answer is B and D.
Step-by-step explanation:
I got it wrong and these we’re correct.
<em><u>The equation to determine the number of species in florida is:</u></em>
<em><u>Solution:</u></em>
Given that,
There are 83 species of butterflies at a butterfly world
That is 38 more than 5/6 of the species x, found in Florida
<em><u>To find: Equation used to determine the number found in Florida</u></em>
From given statement,
83 species of butterflies = 38 more than 5/6 of the species x
Which can be written mathematically as,
Thus the equation to determine the number of species in florida is found
Let us solve the equation
Thus 54 species is found in florida
Answer:
B and D
Step-by-step explanation:
Options are
A. Their confidence interval would be less likely to capture the sample mean.
B. The probability of selecting a sample which doesn't capture the true value of μ would be 10% rather than 5% if they decide to calculate a 90% confidence interval rather than a 95% confidence interval from the sample they will select.
C. They would increase the margin of error of their confidence interval if they calculated a 90% rather than a 95% confidence interval.
D. They would decrease the margin of error of their confidence interval if they calculated a 90% rather than a 95% confidence interval.
A. Confidence interval is pivoted around mean. So this is an incorrect option.
B. 90% sample values around mean will be included in case of 90% confidence interval and 95% sample values around mean wil be included in case of 95% confidence interval. So this option is correct
C. Margin of error increases with increase in confidence interval as likelihood of a sample value deviating from mean increases. So this is incorrect.
D. same explanation as above
