Approximately how many meters are equal to 11.4 feet?Note: 1 m≈3.3 ftRound your answer to the nearest hundredths.

Alright, lets get started.

We are asked, approximately how many meters are equal to 11.4 feet.

We have given that,

3.3 feet = 1 meter

So, 1 feet = $\frac{1}{3.3}$ meter

So, 11.4 feet = $11.4 *\frac{1}{3.3}$ meter

11.4 feet = $\frac{11.4}{3.3}$ meter

11.4 feet = 3.45 meters : Answer

Hope it will help :)

Answer:

7/25

Step-by-step explanation:

θ lies in quadrant ii

so 2θ lies in quadrant iv

csc θ=5/3

sin θ=3/5 (sin θ=1/csc θ)

[cos(α+β)=cosαcosβ-sinαsinβ]

cos (2θ)=cos(θ+θ)=cos θ cos θ-sin θ sin θ=cos² θ-sin ²θ=1-sin²θ-sin²θ=1-2sin²θ

=1-2 (3/5)²

=1-2(9/25)

=1-18/25

=(25-18)/25

=7/25

Answer:

Step-by-step explanation:

Given that Tay-Sachs disease is a genetic disorder that is usually fatal in young children. If both parents are carriers of the disease, the probability that each of their offspring will develop the disease is approximately 0.25.

Let X be the no of children having this disease out of 4 occasions

Then X has two outcomes and each trial is independent of the other trial

Hence X is binomial with n =4, and p = 0.25

a) $P(X=4) = 4C4 (0.25)^4 = 0.003906$

b) $P(X=1) = 4C1 (0.25)(0.75)^3\\= 0.4219$

c) $P(4th child/3 children did not) = 0.25$ since independent.
