Need help with favoring equations. First is m squared minus m minus six

Mathematics
1 answer:
sveticcg [70]3 years ago

Answer:

(m − 3) (m + 2)

Step-by-step explanation:

m² − m − 6

To factor a quadratic ax² + bx + c, you can use the AC method.

1. Multiply a and c.

2. Find factors of ac that add up to b.

3. Divide the factors by a and reduce.

4. The denominators are the coefficients, the numerators are the constants.

Here, a = 1, b = -1, and c = -6.

1. ac = -6

2. Factors of -6 that add up to -1 are -3 and 2.

3. -3/1, 2/1

4. Factors are m − 3 and m + 2.

m² − m − 6 = (m − 3) (m + 2)

Exclain why 0.32 with a line above it is greater than 0.32
ella [17]
"0.32 with a line above it" could refer to two possible numbers, either 0.\overline{32}=0.323232\ldots or 0.3\overline2=0.3222\ldots.

In either case, 0.32 will be the smaller of the two numbers simply because it terminates with two digits after the decimal point, while the others keep going, basically adding a small positive number to 0.32.

A lot of 100 semiconductor chips contains 15 that are defective. three chips are selected at random from the lot without replace
Alex787 [66]
D=event that chip selected is defective
d=event that chip selected is NOT defective

Four possible scenarios for the first two selections:
P(DDD)=15/100*14/99*13/98=13/4620
P(DdD)=15/100*85/99*14/98=17/924
P(dDD)=85/100*15/99*14/99=17/924
P(ddD)=85/100*84/99*15/98=17/154

Probability of third selection being defective is the sum of all cases,
P(XXD)=P(DDD)+P(DdD)+P(dDD)+P(ddD)
=3/20

Answer pls<br> thank you
frosja888 [35]

Answer:

d = 5/6t

Step-by-step explanation:

5 stories every 6 seconds

at 12 seconds, it would have travelled 10 seconds.

using this 2 data in this formula

(y-y1)/(x-x1) = (y2-y1)/(x2-x1)

Note : d = y, t = x;

d1 = 5, t1 = 6, d2 = 10, t2 = 12

we have

(d - 5)/(t-6) = (10-5)/(12-6)

(d - 5)/(t-6) = 5/6

d = 5/6(t-6) + 5

d = 5/6t -5+5

d = 5/6t

Doug estimates that his soccer team will win 7 games this year. The team actually wins 10 games. What is the percent error of Do
baherus [9]

Answer: 30%

Step-by-step explanation:

Percent error = \dfrac{|\text{Estimated value - Actual value}|}{\text{Actual value}}\times100\%

Estimated number of games win this year = 7

Actual number of games won = 10

Now ,   the percent error of Doug’s estimate = \dfrac{|7-10|}{10}\times100\%= \dfrac{3}{1}\times10\%=30\%

Hence, the percent error of Doug’s estimate = 30%
