In ΔCDE, the measure of ∠E=90°, the measure of ∠C=70°, and DE = 12 feet. Find the length of CD to the nearest tenth of a foot
Radda [10]

Answer:

CD = 4.4ft

Step-by-step explanation:

Given

DE = 12

\angle C = 70^\circ

Required

Find CD

This question is represented with the attached triangle

To solve CD, we make use of tan formula.

tan(70) = \frac{DE}{CD}

Substitute 12 for DE

tan(70) = \frac{12}{CD}

Make CD the subject

CD = \frac{12}{tan(70)}

CD = \frac{12}{2.7475}

CD = 4.4ft --- approximated

A coin is tossed 15 times. Find the probability of tossing seven or eight heads.
Mamont248 [21]
We will use Binomial Distribution in this case.

Since the coin is tossed 15 times. N which is the number of trails will be 15.

P = Probability of heads

Q = Probability of tails

X = No. heads occurring in each toss.

So, now we have to find the probability for exactly 10 heads.

P(x = 10) = C(15, 10) P^x Q^N-x

C(15, 10) (1/2)^10 (1/2)^5 = 0.0916

Is the function even, odd, or neither?​
attashe74 [19]
The function is even if f(-x)=f(x) and it’s odd when f(-x)=-f(x)
If the graph is symmetric to the y-axis then it’s even, if the graph is symmetric to the origin it’s odd.

If it doesn’t fit within these then it’s neither.
