Using the slope intercept formula, the equation for the line in slope intercept form is y = -x - 4
<h3>Slope intercept equation</h3>
The slope intercept equation can be describe as follows:
y = mx + b
where
Therefore,
(-4, 0)(1, -5)
m = -5 - 0 / 1 + 4 = -5 / 5 = -1
Therefore, let's find b using (1, -5)
-5 = -1(1) + b
-5 = -1 + b
b = -5 + 1
b = -4
Therefore, the equation is y = -x - 4

Answer: (D) none of the these.
Step-by-step explanation:
- A multimodal distribution refers to a distribution with two or more modes.
If the shape of our data set is multimodal, the it will show two or more peaks which represents the number modes in the data.
Since it has no relation with mean or median of the data, there for the correct option will be "none of these".
Answer:
y=0
Step-by-step explanation:
6y+2=-2(2y-1)
Distribute
6y+2 = -4y +2
Add 4y to each side
6y+2 = -4y +2+4y
6y +2 =2
Subtract 2 from each side
6y +2-2 = 2-2
6y = 0
y=0
Answer:
$219.63
Step-by-step explanation:
Market is the net of price and the cost of the product. It is calculated by applying a defined percentage on cost of the product and added to the cost to make a price to sale.
The wholesale price / cost = $125.50
Mark up rate = 75%
Markup received = $125.50 x 75% = $94.13
Retail Price = Cost + Markup
Retail Price = 125.50 + 94.13 = $219.63
Answer:
A 99% confidence interval will be wider than a 95% confidence interval
Step-by-step explanation:
From the question we are told that
The 95% confidence interval for for the mean foot length for students at the college is found to be 21.709 to 25.091 cm
Generally the width of a confidence interval is dependent on the margin of error.
Generally the margin of error is mathematically represented as
From the above equation we see that
Here is the critical value of the half of the level of significance and this value increase as the confidence level increase
Now if a 99% confidence level is used , it then means that the value of
will increase, this in turn will increase the margin of error and in turn this will increase the width of the confidence interval
Hence a 99% confidence interval will be wider than a 95% confidence interval
