Step-by-step explanation:

factor by grouping, you can group the first two terms and the last two terms:

2h(m-n) + (-3k)(m-n)

there will be one factor in common, use that factor in combination with the factors that are not duplicated:

(2h-3k)(m-n)

**HELP**<br>find the angle measures given the figure is a rhombus.

DIA [1.3K]

Answer:

m<1=74

m<2=37

Step-by-step explanation:

m<2 is the same as the other angle, 37 degrees. So now we need to find the other angle in the triangle.

37+37+x=180.

The total degree of a triangle is 180.

x=106

Subtract that from 180 to get m<1.

180-106=74

I hope this helps!

Good luck!

A certain type of flashlight requires two type-D batteries, and the flashlight will work only if both its batteries have accepta

VikaD [51]

Answer: Our required probability is 0.167.

Step-by-step explanation:

Since we have given that

n = 15

Probability of success p = 80% = 0.8

Probability of failure q = 20% = 0.2

We need to find the probability that at least fourteen will work.

So, by Binomial distribution, we get that

$P(X\geq 14)=P(X=14)+P(X=15)\\\\P(X\geq 14)=^{15}C_{14}(0.8)^{14}(0.2)+^{15}C_{15}(0.8)^{15}\\\\P(X\geq 14)=0.167$

Hence, our required probability is 0.167.

Gabriela Mistral was a poet, diplomat, teacher and humanitarian. Each week she worked a certain amount of days as a poet diploma

Ipatiy [6.2K]

Answer:

Gabriela Mistral works as a humanitarian for $8$ days.

Step-by-step explanation:

Gabriela Mistral was a poet, diplomat, teacher and humanitarian such that each week she worked a certain amount of days as a poet diplomat teacher and humanitarian.

Ratio is $1:1:3:2$

Let $x$ denotes total number of days Gabriela Mistral work.

As she works 12 days as a teacher,

$\frac{3}{7}x=12\\ x=\frac{7}{3}(12)\\ x=28$

Total number of days $=x=28$

So,

she works as a humanitarian for $\frac{2}{7}x=\frac{2}{7}(28)=8$ days.
