The Cubs have won 44 baseball games and have lost 65 games. They have 53 games remaining. At least how many of the remaining 53

Nimfa-mama [501]

More than 50% would be 50% of the total games plus one win.
In total, there are 162 games.
44+65+53=162
50% of 162 equals 81.
The cubs must win 82 games. If they have won 44 games so far, then 82-44=36
They must win at least 56 games to have a winning season.

Hope I got it right for your sake.

400 people were surveyed about their eye color. 8% of the people surveyed have green eyes. how many people had green eyes

VashaNatasha [74]

Answer:

32

Step-by-step explanation:

The problem above can be solved by using the <em>multiplication operation</em>.

Given: 400 people

8% of the people with green eyes

Let's solve:

Let x be<em><u> the number of people with green eyes.</u></em>

x = 400 x 8%

x = 400 x (0.08)

x = 32

So, the number of people surveyed with green eyes is 32. The rest of the surveyed people (368) have a different eye color.

⦁ Find the sum of the series . 15 sigma n=1, (2n-1) Show your work

sergejj [24]

Answer:

225

Step-by-step explanation:

The sum of this series is given by the formula:

$S_n=\frac{n}{2}[2a+(n-1)d]$

Where

S_n is the sum

a is the first term (we get this by plugging in n = 1 into "2n-1", we have 2(1) - 1 = 1)

n is the number of terms (the sum is defined for n = 1 to n = 15, so 15 terms)

d is the common different (the difference is successive terms. Here, 2nd term would be 2(2) - 1 = 3, and first term was 1, so d = 3 -1 = 2)

<em>plugging in the info, we will get the sum:</em>

<em> $S_n=\frac{n}{2}[2a+(n-1)d]\\S_{15}=\frac{15}{2}[2(1)+(15-1)(2)]\\=225$ </em>

<em>The sum is 225</em>

Cos(−θ)=√3/3, sinθ<0

Delicious77 [7]

Answer:

$\sin\theta=-\frac{\sqrt{6}}{3}$

Step-by-step explanation:

The given trigonometric equation is $\cos(-\theta)=\frac{\sqrt{3} }{3}$ .

We can either use the Pythagorean identity or the right angle triangle to solve for $\sin\theta$ .

According to the Pythagorean identity,

$\cos^2\theta+\sin^2\theta=1$

Recall that, the cosine function is an even function, therefore

$\cos(-\theta)=\cos(\theta)$

$\Rightarrow \cos(\theta)=\frac{\sqrt{3} }{3}$ .

We substitute this value in to the above Pythagorean identity to get;

$(\frac{\sqrt{3}}{3})^2+\sin^2\theta=1$

$\Rightarrow \frac{3}{9}+\sin^2\theta=1$

$\Rightarrow \sin^2\theta=1-\frac{3}{9}$

$\Rightarrow \sin^2\theta=\frac{6}{9}$

$\Rightarrow \sin\theta=\pm \sqrt{\frac{6}{9}}$

$\Rightarrow \sin\theta=\pm \frac{\sqrt{6}}{3}$

But we were given that,

$\sin\theta\:$ , so we choose the negative value.

$\Rightarrow \sin\theta=-\frac{\sqrt{6}}{3}$

The correct answer is B
