The slope of the line that contains the points (1, -1) and (2, 3) is 4. What is the y-intercept?

1 answer:

4 0

Y- intercept =-5
y-y1=m(x-x1)
y-(-1)=4(x-1)
y+1=4(x-1)
y+1=4x-4
y=4x-4-1
y=4x-5
Or
y=4x+b
-1=4(1)+b
-1=4+b
-1-4=b
-5=b. Y-intercept is -5

If Santiago wanted to turn his $279.89 into as many nickels as possible, how many would he<br>have?

Elina [12.6K]

Answer:

5,597 nickels and 4 pennies

Step-by-step explanation:

First, we can take away 4 cents since we know 4 isn't divisible by 5.

Our new number would be 279.80

Then, we divide 279.80 by 0.05 since 0.05 is what a nickel equals>

279.85/0.05 = 5597

Therefore, he would have 5,597 nickels and 4 pennies.

At First Class Pizza, 12% of the pizzas made yesterday were pepperoni pizzas. If 27 pizzas have pepperoni, how many pizzas were

gogolik [260]

Answer: 225

Step-by-step explanation:

Let the total number of pizza made be represented by x.

Therefore, the situation in the question can be written as:

12% × x = 27

12/100 × x = 27

0.12 × x = 27

0.12x = 27

Divide both side by 0.12

0.12x/0.12 = 27/0.12

x = 225

The total pizza made was 225.

Answer:

(a) H0:μ1=μ2; Ha:μ1≠μ2, which is a two-tailed test.

Step-by-step explanation:

We formulate the

H0: μ1=μ2; null hypothesis that the two means are equal and alternate hypothesis that the two mean are not equal.

Ha:μ1≠μ2 Two tailed test

Test statistic used is

t= x1`-x2` / s√n as the variances are equal and sample size is same

T value for 9 degrees of freedom for two tailed test at α = 0.05 is 2.26

P- value for t test for 9 degrees of freedom is 0.125 from the table.

Hence only a is correct .
