Explanation:
A = number of people who play basketball onlyB = number of people who play baseball onlyC = number of people who play both sports5 play basketball, 2 play both, which means 5-2 = 3 play basketball only. So A = 3.
12 play baseball, 2 play both, which means 12-2 = 10 play baseball only. So we have B = 10.
We have A+B+C = 3+10+2 = 15 people who play one sport, or the other, or both. This is out of 27 total. So that's what leads us to the answer 15/27.

Answer:
316.2 m/s
Step-by-step explanation:
What the problem statement doesn't tell you is that the value of m in the formula must have units of kilograms. 17 grams is 0.017 kilograms, so the velocity is ...
[tex]v=\sqrt{\dfrac{2K}{m}}=\sqrt{\dfrac{2(850)\text{ J}}{0.017\text{ kg}}}=\sqrt{100\,000}\text{ m/s}\approx316.2\text{ m/s}[/tex]
_____
Additional comment
If you simply put the numbers into the formula without regard to correct units, you might be led to believe the velocity is 10 m/s. That would be the speed of a 17 kg object with an energy of 850 J.
Psychologists in Montreal and Toronto conducted a study to determine if babies show any preference for speech over general noise.1 Fifty infants between the ages of 4-13 months were exposed to both happy-sounding infant speech and a hummed lullaby by the same woman. Interest in each sound was measured by the amount of time the baby looked at the woman while she made noise. The mean difference in looking time was 27.79 more seconds when she was speaking, with a standard deviation of 63.18 seconds. Perform the appropriate test to determine if this is sufficient evidence to conclude that babies prefer actual speaking to humming.
Required:
State the null and alternative hypotheses.
Answer:
H0 : μ1 - μ2 = 0
H1: : μ1 - μ2 ≠ 0
we reject the Null and we conclude that babies prefer actual speaking to humming.
Step-by-step explanation:
H0 : μ1 - μ2 = 0
H1: : μ1 - μ2 ≠ 0
Mean difference, d = 27.79
Standard deviation of difference, Sd = 63.18
Sample size, n = 50
The test statistic :
d / (Sd / √n)
Test statistic :
27.79 / (63.18 / √50)
27.79 / 8.9350012
= 3.11
Using the Test statistic score, we can obtain the Pvalue
Using the standard normal table ;
Pvalue = P(x<-Z or x>Z) = 0.0018709
Pvalue is very low
Pvalue < α ; Hence, we reject the Null and we conclude that babies prefer actual speaking to humming.

2. A movie theater charges $15 for adults and children and $10 for seniors. A
total of $1,270 was collected for movie ticket sales one night for a selected
movie. The total number of tickets sold for that movie was 93. How many
adult and senior tickets were sold?
b. Write the equations:
Answer:
A. Adult=68, seniors=25B. 10a + 10s=1270. a + s=93
Step-by-step explanation:
15a + 10s =1270 equation 1
a + s =93 equation 2
a=93-s. Isolate a for equation 2
15(93-s) + 10s =1270 substitute value of a in equation 2 (93-s) with value of a in equation 1
1395-15s+10s=1270
-5s=-125
S=25
solve for a
a + s =93
a + 25=93
a=68
‘check answer
15a + 10s=1270
15(68) + 10(25)=1270
1020+ 250=1270

#37. What is the next step when solving the equation sin (2x) - sin (x) = 0
sin(2x) - sin(x) = 0
Expand the first term using the double angle identity:
2 sin(x) cos(x) - sin(x) = 0
Factor out sin(x) :
sin(x) (2 cos(x) - 1) = 0
This leaves you with 2 cases that can be solved separately:
sin(x) = 0 or 2 cos(x) - 1 = 0
sin(x) = 0 or cos(x) = 1/2
[x = 2nπ or x = π + 2nπ] or [x = π/6 + 2nπ or x = 5π/6 + 2nπ]

the line ab has midpoint (-2,4). a has coordinates (3,-2). find the coordinates of b
Answer:
B = (-7,10)
Step-by-step explanation:
Given that , a line AB has midpoint (-2,4) and the coordinates of A is ( 3 , -2). We need to find out the coordinates of B .
Let coordinate of B be ( p,q ). We can use midpoint formula , as ,=> Midpoint = ( x₁ + x₂ / 2 , y₁ + y₂/2 )
=> ( -2,4 ) = ( p + 3)/2 , ( q -2 )/2
On comparing ,=> -2 = p + 3/2
=> p + 3 = -4
=> p = -3 - 4
=> p = (-7)
Also :-
=> q - 2/2 = 4
=> q -2 = 8
=> q = 8 + 2
=> q = 10
Hence the coordinates of B is ( -7,10 ) .Jimmy spent $32.50 at the bowling alley. He spent $5 to rent shoes and the rest he spent on bowling l, which cost $5.50 per game. What are the 2 steps and how much games did jimmy bowl?

Mrs.Oswalt has been craving smoothies lately. She buys a 20oz chocolate smoothie for 7$. Ms.Munguia buys a 17oz chocolate smoothie. How much is Ms.Munguia’s smoothie?
A. 5.95$
B. 8.24$
C. 6$
Answer:
Cost of 17 oz smoothies = $5.95
Step-by-step explanation:
Given:
Amount of smoothies Mrs. Oswalt buy = 20 oz
Cost of 20 oz smoothies = $7
Amount of smoothies Ms. Munguia buy = 17 oz
Find;
Cost of 17 oz smoothies
Computation:
Cost of 17 oz smoothies = Cost of 20 oz smoothies[Amount of smoothies Ms. Munguia buy / Amount of smoothies Mrs. Oswalt buy]
Cost of 17 oz smoothies = 7[17/20]
Cost of 17 oz smoothies = 119 / 20
Cost of 17 oz smoothies = $5.95

Answer:
Step-by-step explanation:
the instruction say put it in this form Ax +Bx = C , but i'm sure they were meant to say this Ax +By = C note the X and Y differences. I'll use the latter form, b/c that's the "standard" form
find the slope:
m = -11 - (-5) / -10-5
m = -11 + 5 / -15
m = -6 / -15

y + 5 = 2x/5 -2
y = [tex]\frac{2}{5}[/tex] x - 7
- [tex]\frac{2}{5}[/tex] x +y = -7

Which interval represents 75% of the data in the box-and-whisker plot?
Answer:
27.5-32.5
Step-by-step explanation:
Makayla goes bowling.
She has $25.00 to spend.
She spends $4.25 to rent shoes.
She spends $2.50 for each game he bowls.
Which inequality can Makayla use to determine x, the greatest number of games he can bowl?
A) 2.5 +4.25x > 25
B 4.25 + 2.5x > 25
2.5 + 4.25x < 25
D 4.25 +2.5x < 25
Answer:
4.25 + 2.50x < 25
Step-by-step explanation:
Makayla can't spend more than $25 and you pay an initial fee of 4.25 for the shoes and 2.50 for each game so the inequality would be
D.) $4.25 + 2.50x < 25.
