Answer:

HJ = 5.20

HI = 3

angle J = 30 degrees

Step-by-step explanation:

sin 60 = HJ/6

HJ = 5.20

cos 60 = HI/6

HI = 3

angle J = 90-60 = 30 degrees

8a^3 b^8+4ab^5-16ab^8= <br> need help plz! (factor completely)

lakkis [162]

We can factor out the 4 to get
4(2a^3b^8+ab-4ab^8)
we can also factor out the ab
4ab(2a^2b^7+1-4b^7)
that is factored completely

a data set has a mean of 68 and standard deviation of 6. An element in this set is 51. What is z-score for 51? Round your answer

gogolik [260]

z = -2.83

<u>Explanation:</u>

Given:

Mean, μ = 68

Standard deviation, σ = 6

Data point, x = 51

Z score, z = ?

We know:

$z = \frac{data point - mean}{standard deviation} \\\\z = \frac{x - u}{p}$

Substituting the value we get:

$z = \frac{51-68}{6} \\\\z = -2.83$

A negative z score says that the data point is below average.

Which of the following expressions is equal to 5 to the 6th power divided by 5 to the 5th power

Jobisdone [24]

Asey

remember
$\frac{x^m}{x^n}=x^{m-n}$
so

$\frac{5^6}{5^5}=5^{6-5}=5^1=5$

Yesterday,Annie walked 9/10 mile to her friend's house.Together,they walked 1/3 mile to the library.Which is the best estimate f

Elina [12.6K]

To solve, you need to find the least common multiple of the denominator.

In this case, its 30.

3*9= 27/30

1*10 = 10/30

She walked 37/30 miles or 1 mile and 7/30th of a mile

simplifying $\frac{\sqrt{4}}{\sqrt[3]{4}}$ we get $4^{\frac{1}{6}}$

Option B is correct.

Step-by-step explanation:

We need to simplify: $\frac{\sqrt{4}}{\sqrt[3]{4}}$

Solving:

$\frac{\sqrt{4}}{\sqrt[3]{4}}$

We know that √ = 1/2 and ∛=1/3

$\frac{4^{\frac{1}{2}}}{4^{\frac{1}{3}}}$

Applying exponent rule: $\frac{x^a}{x^b}=x^{a-b}$

$=4^{\frac{1}{2}-\frac{1}{3}}\\=4^{\frac{3-2}{6}}\\=4^{\frac{1}{6}}$

So, simplifying $\frac{\sqrt{4}}{\sqrt[3]{4}}$ we get $4^{\frac{1}{6}}$

Option B is correct.
