what two numbers multiply to equal -50 but adds up to equal 5
Answers
Answer:
10 and -5
Step-by-step explanation:
x + y = 5
xy = -50
y = 5 - x
x(5-x) = -50
5x - x^2 = -50
x^2 - 5x - 50 = 0
from there on we can solve the classic way
[tex]\Delta = (-5)^2 - 4\cdot1\cdot(-50) = 25 + 200 = 225\\\sqrt{\Delta} = 15\\x_1 = \frac{5 - 15}{2} = -5\\x_2 = \frac{5+15}{2} = 10\\y_1 = 5 - x_1 = 10\\y_2 = 5 - x_2 = -5[/tex]
Everything checks out.
Answer:

Answers
Answer:
He had 5 minutes left for question C.
Step-by-step explanation:
20 minutes to do the quiz.
He spent:
11 minutes on question A
4 minutes of question B.
So, for the first 2 questions, he used 15 minutes.
How much time did he have left for question C?
Total of 20 minutes, in the first two questions he used 15. So
20 - 15 = 5
He had 5 minutes left for question C.

In a room at a museum, we want to tile the floor. If the floor measures 15 feet by 55 feet, what is the largest-size square tile that we can use to tile the floor without having to cut tiles?
A) 11 ft by 11 ft
B) 5 ft by 11 ft
C) 5 ft by 3 ft
D) 3 ft by 3 ft
E) 11 ft by 3 ft
F) 5 ft by 5 ft
Answers
Answer:
B. 5 foot by 11 foot
the numbers have to be divisible in both directions.
11x11 doesn't work, because at 15 feet wide one tile isn't wide enough, and 2 is too wide.
5x11 works- 3x5= 15 and 11x5=55. you'd use 15 tiles.
the rest are all smaller.

Suppose that for the random sample of 100 Cal Poly students the mean number of hours per day spent watching TV turns out to be 3.01 hours, and the standard deviation of the number of hours per day spent watching TV turns out to be 1.97 hours.
a. Is the number 1.97 a parameter or a statistic? Assign an appropriate symbol to this number.
b. Find the standardized statistic to investigate whether the data provide evidence that the average number of hours per day Cal Poly students spend watching TV is different from 2.75 hours.
c. What is your conclusion about the hypotheses, based on the calculated value of the standardized statistic? How are you deciding?
Answers
Answer:
a. 1.97 is a statistic
b. t test is = 1.32
p value = 0.186
c. there is not enough evidence to support our claim
Step-by-step explanation:
a. 1.97 is not a parameter it is a statistic. It is the standard deviation of the sample. we represent this with the symbol s.
b. we are claiming that the mean hours that are spent watching television is different from 2.75
we form our hypothesis as:
h0; u = 2.75
h1: u not equal to 2.7
t stat = barx - u/s/√n
= 3.01-2.75/(1.97/√100)
= 0.26/(1.97/10)
= 0.26/0.197
= 1.32
we get p value
n = 100
df = 100-1 = 99
using t distribution, pvalue = 0.1899
c. the p value is higher than our alpha level here
0.189 > 0.05, so we fail to reject H0. our conclusion is that there is not enough evidence to show that μ is different from 2.75

You buy halibut at $25 per pound.one portion of seared halibut requires 6 ounces of halibut.how much does the halibut for one portion cost ?
Answers
Answer:
$9.38
Step-by-step explanation:
halibut is measured in pounds and a portion is measured in ounces
in order to determine the cost, the two units have to be comparable. So, ounces have to be converted to pounds
1 ounce = 0.0625 pounds
6 ounces = 0.0625 x 6 = 0.375 pounds
0.375 pounds would cost 0.375 pounds x 25 pounds = $9.38

Use order of operations to solve in the bracket.
2x + 20 - ( 5X3) = 30
2x + 20 - (15) = 30
Now open the brackets.
2x + 20 - 15 = 30
2x + 5 = 30
Subtract both sides by 5
2x = 25
Divide both sides by 2.
