Yes, you can claim that the null hypothesis. But you must pay attention the p-value. If the p-value is higher than the significant value the null hypothesis can't be rejected.

Answer:

Page 1 Answer: \frac{9}{5}

Page 2 Answer: 175

Page 3 Answer: Alicia used 1.5 gallons to travel a distance of 37.5 miles.

Page 4 Answer: I think its 117 but I could be wrong...

Step-by-step explanation:

Page 1:

We just simplify \frac{36}{20} by dividing and get 9/5

Page 2: Since they want to DOUBLE her amount in her savings, we double her current amount (125) and get 250 by adding.

Next, we subtract 125 from 300 in her checking and get 175.

Page 3:

We use the titles so solve the graph.

Hello! I graduated in 2008 but forgot how to solve multiplication. It's been so long. However I want to be refreshed on solving
Anettt [7]
To do this you first have to set this up vertically.
First you multiply through with the 2 (44×2=88). Then next, you have to multiply through with the 1 (44×1=44) But since this is the second line, you have to add the 0 to the end (440).
Now you simply add 88+440=528.

If the discriminant is positive how many solutions are there
ddd [48]

Answer:

b^2-4ac>0 yields 2 real roots

Step-by-step explanation:

To find the number of real roots for a quadratic, we apply the discriminate. The discriminate is the inside portion of the square root from the quadratic formula.

• b^2-4ac>0 yields 2 real roots

• b^2-4ac=0 yields 1 real root

• [tx]b^2-4ac<0[/tex] yields no real roots

Example:

4x^2-7x+2=0 where a=4, b=-7, and c=2

b^2-4ac=(-7)^2-4(4)(2)=49-32=17.

It has 2 real roots
