Find a point-slope form for the line that satisfies the stated conditions. Slope , passing through (-5,4)
I really need this question answered
By:
I don't see a value for the slope. We need that to set the equation, otherwise I can write an unlimited number of equations that pass through (-5,4).
I'll assume a slope so that you can see how the procedure would work. I like 6, so we'll assume a slope of 6.
The equation for a straight line has the form y = mx + b, where m is the slope and y is the y-intercept, the value of y when x = 0. We want a line that has slope 6, so:
y = 6x + b
We need to find b, so substitute the point (-5,4) that we know is on the line:
4 = 6*(-5) + b and solve for b
4 = -30 + b
b = 34
The line is y = 6x + 34
Complete question :
70% of a certain species of tomato live after transplanting from pot to garden. Najib transplants 3 of these tomato plants. Assume that the plants live independently of each other. Let X = the number of tomato plants that live.
What is the probability that exactly 2 of the 3 tomato plants live?
You may round your answer to the nearest hundredth.
Answer:
0.44
Step-by-step explanation:
Given that :
P(live after transplanting) = 0.7
Assume plants live independently of each other :
Number of tomatoes transplanted = 3
Number of potatoes that live = x
Probability that exactly 2 of the 3 tomatoes live?
Using binomial probability ;
p = 0.7
1 - p = 1 - 0. 7 = 0.3
P(x = x) = nCx * p^x * (1 - p)^(n-x)
P(x = 2) = 3C2 * 0.7^2 * 0.3^(3-2)
P(x = 2) = 3C2 * 0.7^2 * 0.3^1
P(x = 2) = 3 * 0.49 * 0.3
P(x = 2) = 0.441
= 0.44 ( nearest hundredth)
I would say either a or b
Answer:
The p value for this case is given by:
For this case the p value is higher than the significance level given so we have enough evidence to FAIL to reject the null hypothesis and we can't conclude that the true mean is significantly less than 409
Step-by-step explanation:
Information given
represent the sample mean
represent the population standard deviation
sample size
represent the value to verify
represent the significance level for the hypothesis test.
z would represent the statistic (variable of interest)
represent the p value
Hypothesis to test
We want to verify if the true mean is less than 409, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The statistic for this case is given by:
(1)
Replacing the info we got:
The p value for this case is given by:
For this case the p value is higher than the significance level given so we have enough evidence to FAIL to reject the null hypothesis and we can't conclude that the true mean is significantly less than 409
