Step-by-step explanation:
what two numbers multiply to equal -50 but adds up to equal 5
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:
-5 × 10 = -50

Step-by-step explanation:
f - 4.1 = 8.6
please help i need ur help please
Answer:
f=12.7
Step-by-step explanation:
Answer:
12.7
Step-by-step explanation:
To find f, we need to "reverse" the operation and do 8.6 + 4.1 which equals 12.7.
Double check: 12.7 - 4.1 = 8.6 which is true. Therefore, 12.7 = f.

4+5[tex]4+5\frac{x}{y} 3x^{2} - 3x^{2}[/tex]
Answer:
[tex]58 + \frac{ {15x}^{3} }{y} - {3x}^{2} [/tex]
Step-by-step explanation:
1) Use this rule: a/b × c/d = ac/bd.
[tex]4 + 54 + \frac{5x \times {3x}^{2} }{y} - {3x}^{2} [/tex]
2) Take out the constants.
[tex]4+54 + \frac{(5 \times 3) {xx}^{2} }{y} - {3x}^{2} [/tex]
3) Simplify 5 × 3 to 15.
[tex]4 + 54 + \frac{ {15xx}^{2} }{y} - {3x}^{2} [/tex]
4) Use the product rule: x^a x^b = x^a + b.
[tex]4 + 54 + \frac{15xx^{2} }{y} - 3x^{2} [/tex]
5) Simplify 1 + 2 to 3.
[tex]4 + 54 + \frac{15 {x}^{3} }{y} - {3x}^{2} [/tex]
6) Collect like terms.
[tex](4 + 54) + \frac{15 {x}^{3} }{y} - {3x}^{2} [/tex]
7) Simplify.
[tex]58 + \frac{ {15x}^{3} }{y} - {3x}^{2} [/tex]
Therefor, the answer is 58 + 15x³ / y - 3x².
There are 250 tables total in a cafeteria. There are 150 tables with red tablecloths and 100 tables with white tablecloths. As people walk into the cafeteria they are randomly assigned to a table. What is the probability of the first person through the door of being sat at a table with a red tablecloth? SIMPLIFY
Answer:
60%
Step-by-step explanation:
If there are 250 tables you can multiply it by 4 to work with 1000. This means you have to multiply the other table cloth numbers. 150 x 4 = 600. 100 x 4 = 400. Once you simplify you can get 40 white and 60 red out of 100. 60/100 = 60%.

Answer:
C)
Step-by-step explanation:
As it is 60 degree, and the whole circle is 360 degree, so we need to find 1/6 of the circumference of a circle, as C = 2*pi*r = 2*pi*3 = 6pi and 1/6 of it is pi.

USA Today reports that about 25% of all prison parolees become repeat offenders. Alice is a social worker whose job is to counsel people on parole. Let us say success means a person does not become a repeat offender. Alice has been given a group of four parolees. Find the probability P(r) of r successes ranging from 0 to 4. (Round your answers to three decimal places.)
P(0) =
P(1) =
P(2) =
P(3) =
P(4) =
What is the expected number of parolees in Alice's group who will not be repeat offenders? What is the standard deviation?
Answer:
P(0) = 4C0 * 0.75⁰ * 0.25⁴ = 0.00390625 . = 0.004
P(1) = 4C1 * 0.75¹ * 0.25³ = 0.046875 . . . = 0.047
P(2) = 4C2 * 0.75² * 0.25² = 0.2109375 . . = 0.211
P(3) = 4C3 * 0.75³ * 0.25¹ = 0.421875 . . . = 0.422
P(4) = 4C4 * 0.75⁴ * 0.25⁰ = 0.31640625 . = 0.316
Check:
P(0) + P(1) + P(2) + P(3) + P(4) = 1 . . . ok

Answer:
it is 23. always remember it's supposed to add up to 180. So add up all your numbers and subtract the total from 180 to get your answer
Answer:
113 degrees
Step-by-step explanation:
ABF= 39 degrees
ABE= 51 degrees
ABD= 23 degrees (BE is a right angle, which is 90 degrees, 90-67=23
39+51+23= 113

Reconsider Dr. Sameer's research question about how much time Cal Poly students spend on watching television. 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?
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
