Answer:

Option B

Step-by-step explanation:

Given that there are 200 students in 7th grade

Volley ball players = 12% = 24

Baseball players = 15% = 30

Both players = 4

We have to find out the probability that a student plays either volley ball or baseball

No of students who play either base ball or volley ball =

24+30-4= 50

Probability that student plays either volleyball or baseball

=\frac{50}{200} =0.25

In percent this equals 25%

Option b

P(volleyball and baseball) = 4/200 x 100 = 2%
P(either volleyball or baseball) = P(volleyball ∪ baseball) = P(volleyball) + P(baseball) - P(volleyball and baseball) = 12% + 15% - 2% = 25%.

25% play either volleyball or baseball.

The number of items (N) that can be purchased for a given amount of money is inversely proportional to the cost (C) of an item.
mars1129 [50]

Answer:

436 items

Step-by-step explanation:

When a quantity A is inversely proportional to another quantity B, we can write:

A=\frac{k}{B}

Where k is the proportionality constant  [that we need to find]

For this problem, we can write the ratio as:

N=\frac{k}{C}

Now given N = 480 and C = 4.90, we first find k:

N=\frac{k}{C}\\480=\frac{k}{4.90}\\k=4.90*480\\k=2352

Now, as second step, we need this time to find N, when

C = 5.40

Note, we know know k = 2352, so we find N:

N=\frac{k}{C}\\N=\frac{2352}{5.40}\\N=435.55

Rounding to next whole number, we have 436 items

Which is an estimate of LaTeX: \sqrt{14}<br> 14<br> to the nearest hundredth?
Mariana [72]

Answer:

3.74

Step-by-step explanation:

Square root of a number is the number that multiplies by itself to result in, in this case, 14.  The number is irrational, often, though here is close to 3.74, according to the calculator.  Many, though not all, courses recommend calculators for determining square roots, as the mathematical process is quite complex and often not taught.  Try this if your course allows, and if not, wow that's a tough course.

Find the x-intercept(s) of y = 2x2 - 3x - 5.<br> A) -5 <br> B) 2 1/2, -1<br> C) 3, -5 <br> D) 5, -1
Alexus [3.1K]

Answer:

\large\boxed{B)\ 2\frac{1}{2},\ -1}

Step-by-step explanation:

x-intercepts are for y = 0.

We have the equation:

y=2x^2-3x-5

Therefore

2x^2-3x-5=0\\\\2x^2+2x-5x-5=0\\\\2x(x+1)-5(x+1)=0\\\\(x+1)(2x-5)+0\iff x+1=0\ \vee\ 2x-5=0\\\\x+1=0\qquad\text{subtract 1 from both sides}\\\boxed{x=-1}\\\\2x-5=0\qquad\text{add 5 to both sides}\\2x=5\qquad\text{divide both sides by 2}\\\boxed{x=2\frac{1}{2}}
