Answer:
f(2)=7
Step-by-step explanation:
Plug it in
f(x)=2^x+3
f(2)=2^2+3
f(2)=4+3
f(2)=7
If this helps please mark as brainliest
Answer:
f(2) = 7
Step-by-step explanation:
The answer is found by plugging in the value of f(2) in to the equation for f(x):
f(2) = 2^(2) + 3
First calculate the exponents.
f(2) = 4 + 3
Then simplify.
f(2) = 7

the card drawn is:
Note: Give your answer as a fraction in simplest form or as a decimal rounded to the
nearest thousandths place.
a) a face card?
b) a red card?
c) a queen?
d) a club?
e) an Ace or 10?
Answer:
a) 12/52 = 3/14
b) 26/52 = 1/2

a) there are 12 face cards and 52 in the deck
b) half the cards are red, the other half black
c) one queen in each of four suits
d) the deck is broken up into 4 equal suits (hearts, diamonds, spades, clubs) so there are 13 of each.
e) like the answer in part C, there is one of each card in each of the four suits. that gives us four aces and four tens.

The function f(x) varies inversely with x and f(x)=0.5 when x = 0.3. What is f(x) when x = 2.4? A)5.76 B)0.0625 C)0.30 D)0.15
Answer:
B) 0.0625
Step-by-step explanation:
f(x) = k / x
f(x)=0.5 when x = 0.3
f(x) = k / x
0.5 = k / 0.3
Cross product
0.5 * 0.3 = k
k = 0.15
What is f(x) when x = 2.4?
f(x) = k / x
f(x) = 0.15 / 2.4
f(x) = 0.0625
The answer is B) 0.0625

A 95 percent confidence interval for the difference between the proportion of high school seniors who play a varsity sport in the school district and high school juniors who play a varsity sport in the school district is to be calculated. What is the standard error of the difference
Answer: Hello your question is incomplete below is the complete question
In a large school district, 16 of 85 randomly selected high school seniors play a varsity sport. in the same district, 19 of 67 randomly selected high school juniors play a varsity sport. a 95 percent confidence interval for the difference between the proportion of high school seniors who play a varsity sport in the school district and high school juniors who play a varsity sport in the school district is to be calculated. What is the standard error of the difference
answer : 0.0695
Step-by-step explanation:
First step : Determine the sample proportions
For P1 = 16 / 85 = 0.188
For P2 = 19 / 67 = 0.284
Next determine the Standard error of the difference using the relation below
Standard Error = [tex]\sqrt{\frac{p1(1 - p1)}{n1} + \frac{p2(1-p2)}{n2} }[/tex] ------- ( 1 )
where : P1 = 0.188
P2 = 0.284
n1 = 85 high school seniors
n2 = 67 high school juniors
Input values into equation 1
Standard error of the difference = 0.0695

Answer:
the period is the to top points of the highest points on top of the crests
The period of function is,
P = 5
Since, In order to find the period of a graph in general, first, find the period of the parent function, and divide that by the absolute value of the coefficient of the independent variable.
Here, Graph of function is shown.
Hence, The period of function is,
P = 10/2
P = 5
Because there is two wave are shown.

The students who attend Memorial High School have a wide variety of extra-curricular activities to choose from in the after-school program. Students are 38% likely to join the dance team; 18% likely to participate in the school play; 42% likely to join the yearbook club; and 64% likely to join the marching band. Many students choose to participate in multiple activities. Students have equal probabilities of being freshmen, sophomores, juniors, or seniors. What is the probability of the intersection of being a junior and participating in marching band?
0.89
0.39
0.16
0.73
Answer:
0.16
Step-by-step explanation:
I took the test
Probability of the intersection of being a junior and participating in marching band = 0.16
What do we mean by Probability?The probability of an event taking place is the numeric value determining how likely that particular event is to take place.
It is determined by the formula,
Probability( Event ) = Number of favorable outcomes for that event/Total number of outcomes.
The summation of all probabilities for a given event is 1.
What do we mean by the intersection of Probabilities?The intersection of Probabilities is just the product of the two probabilities.
How do we solve the given question?In the question, we are said that students have equal probabilities of being freshmen, sophomores, juniors, or seniors.
∴ Probability(A student is a junior) = 1/4 = 0.25, as we have 4 cases all equally probable.
Now, we are said that a student is 64% likely to join the marching band.
∴ Probability( A student joins marching band) = 64% = 64/100 = 0.64.
We are asked to find the probability of the intersection that a student is a junior and participates in the marching band.
Probability( A student is a junior and joins marching band) = Probability( A student joins marching band)* Probability( A student is a junior)
∴ Probability( A student is a junior and joins marching band) = 0.64*0.25 = 0.16
∴ Probability of the intersection of being a junior and participating in marching band = 0.16

What is a rectangle?A rectangle is a 2-D shape with length and width.
The length and width are different.
If the length and width are not different then it is a square.
The area of a rectangle is given as:
Area = Length x width
We have,
The area of the first fabric scrap is:
A = width x length
A = (2x)(5x)
A = 10x²
The area of the entire quilt is 5 feet wider and 3 feet longer than the first fabric scrap.
Therefore, the width of the quilt is (2x + 5) feet and the length is (5x + 3) feet.
So, the area of the quilt.
A = width x length
A = (2x + 5)(5x + 3)
A = 10x² + 16x + 15
Therefore,
The function that gives the area, f(x), of the quilt in square feet is
f(x) = 10x² + 16x + 15
