Distribute first
a(b+c)=ab+ac
7y(8y-7)=56y^2-49y

now we have
56y^2-49y+46y
56y^2-3y
tada

Measure of missing angle
Debora [2.8K]

Answer:

44 degrees.

Step-by-step explanation:

Since angle A is 46 degrees, and angle C is 90 degrees (because of the right angle) you add 46 and 90 (you get 136) then subtract it from 180 (since every triangle equals 180 degrees) which gets you to 44 degrees.

PLEASE HELP!!!!
Bogdan [553]

Answer:

Step-by-step explanation:

We would apply the formula for binomial distribution which is expressed as

P(x = r) = nCr × p^r × q^(n - r)

Where

x represent the number of successes.

p represents the probability of success.

q = (1 - r) represents the probability of failure.

n represents the number of trials or sample.

From the information given,

p = 18% = 18/100 = 0.18

q = 1 - p = 1 - 0.18

q = 0.82

n = 5

Therefore,

P(x ≤ 2) = p(x = 0) + p(x = 1) + p(x = 2)

P(x = 0) = 5C0 × 0.18^0 × 0.82^(5 - 0)

P(x = 0) = 0.37

P(x = 1) = 5C1 × 0.18^1 × 0.82^(5 - 1)

P(x = 1) = 0.41

P(x = 2) = 5C2 × 0.18^2 × 0.82^(5 - 2)

P(x = 2) = 0.18

Therefore,

P(x ≤ 2) = 0.37 + 0.41 + 0.18 = 0.96

I am struggling with these questions. Please help
Sauron [17]

Answer: Just apply the formula

Step-by-step explanation:

The equation for volume of a cone is:

V_{(cone)} =\frac{1}{3} \pi r^{2} h

The radius is the line that creates a 90 degree angle with the height

The height goes from the base to the tip of the cone.

I recommend leaving Pi as it is and plugging the rest of the numbers first.

Then at the end multiply by 3.14 and round at the end.

This way, it is easier to avoid calculation errors.
