Amy brought a bag of lollipops. It contained 30 lollipops and 6 of them were grape flavored. What would be a good prediction of

harina [27]

Answer:

20 grape lollipops

Step-by-step explanation:

From the 30 lollipops, 6 were grape

P(grape) = grape/total

=6/30

=1/5

If we get 100 lollipop, to determine the number that would be grape, we multiply the number of lollipops by the probability that they are grape

grape = number * probability

= 100 * 1/5

=20

(20 points)Solve the equation cos x = sin (x + 22)

Law Incorporation [45]

Answer:

$\bold{x = 34^\circ}$

Step-by-step explanation:

Given:

$cos x = sin (x + 22^\circ)$

To solve:

The given equation.

Solution:

First of all, let us consider an important property of sine and cosine.

$sin(90^\circ-\theta )=cos\theta$

$cos(90^\circ-\theta )=sin\theta$

We can apply above property to solve for $x$ as per given equation.

$cos x = sin (x + 22^\circ)$

Changing $cosx$ to sine form:

$cosx=sin(90^\circ-x)$

$cosx=sin(90^\circ-x) = sin(x+22^\circ)$

$\therefore 90^\circ-x=x+22^\circ\\\Rightarrow 90^\circ-22^\circ=x+x\\\Rightarrow 2x=68^\circ\\\Rightarrow \bold{x = 34^\circ}$

So, solution to the equation $cos x = sin (x + 22^\circ)$ is:

$\bold{x = 34^\circ}$
