Answer:
C) f(x) = 6.25x + 3
Step-by-step explanation:
In order to know which one of the functions could produce the results in the table we simply need to substitute the number of candy bars for x in the function and solve it to see if it provides the correct total weight shown in the table. If we do this with the functions provided we can see that the only one that provides accurate results would be
f(x) = 6.25x + 3
We can input the # of candies for x and see that it provides the exact results every time as seen in the table.
f(x) = 6.25(1) + 3 = 9.25
f(x) = 6.25(2) + 3 = 15.50
f(x) = 6.25(3) + 3 = 21.75
f(x) = 6.25(4) + 3 = 28

find tan 0 where 0 is the angle shown
Answer:
Because tan represents [tex]\frac{opposite}{adjacent}[/tex] from θ (theta), the equation should be [tex]tan0[/tex]=[tex]\frac{15}{x}[/tex]. Let's leave this equation like that. Now, we need to find the unknown side length, x. We need to use Pythagorean Theorem, because we're given the other two side lengths. The equation should be [tex]x^{2}+15^{2}=17^{2}[/tex]. X should equal ±8 or 8, because a side length can't be a negative value. Now, we can plug in 8 into the equation to get [tex]tan0=\frac{15}{8}[/tex].

a man has 25 coins in his pocket all of which are dimes and quarters. if the total value of his change is 430 cents, how many dimes and how many quarters does he have?
Answer:16 quarters and 3 dimes
Step-by-step explanation:
430/25 (Quarters) = 17
25x16
(Because you can’t have 17 since 25x17=425 leaving no room for dimes.)
=400
Now 430-400=30
30 more cent is needed,
30/10(Dime value)
Is 3, so the answer is the man has 16 quarters and 3 dimes
the ratio of the length of two similar re rectangles is 3 ratio 4. what is the scale ratio of their areas in
full solving
Answer:
9:16
Step-by-step explanation:
The ratio of sides of the lengths of rectangles is 3:4.
Now since the scale is constant. So the scale ratio of area will be square of the side ratio .That is :-
→ Ratio of Area = ( 3 : 4)²
→ Ratio of Area = (3/4)²
→ Ratio of Area = 9/16
→ Ratio of Area = 9:16
Hence the ratio of areas is 9:16 .help lol plsssss!!?!?
Answer:
3y-x =-6
Step-by-step explanation:
The equation of a line in point slope form is expressed as;
y-y0 = m(x-x0)
(x0, y0) is the point = (3, -1)
Given the equation 3xs+y = 1
Get the slope
y = -3x + 1
mx = -3x
m = -3
Since the equation needed is perpendicular to the line, the slope will be expressed as;
M = -1/-3
M = 1/3
Substitute and get the equation needed
y-y0 = m(x-x0)
y - (-1) = 1/3(x-3)
y+1 = 1/3(x-3)
3(y+1) = x-3
3y+3 = x-3
3y - x = -3-3
3y-x =-6
This gives the required equation

The Wilson family was one of the first to come to the U.S. They had 8 children. Assuming that the
probability of a child being a girl is .5, find the probability that the Wilson family had:
at least 5 girls?
at most 5 girls?
Answer:
0.3634 = 36.34% probability that the Wilson family had at least 5 girls.
0.8554 = 85.54% probability that the Wilson family had at most 5 girls.
Step-by-step explanation:
For each children, there are only two possible outcomes. Either it is a girl, or it is not. The probability of a child being a girl is independent of any other child. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
They had 8 children.
This means that [tex]n = 8[/tex]
The probability of a child being a girl is .5
This means that [tex]p = 0.5[/tex]
Probability that the Wilson family had: at least 5 girls?
This is:
[tex]P(X \geq 5) = P(X = 5) + P(X = 6) + P(X = 7) + P(X = 8)[/tex]
In which
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 5) = C_{8,5}.(0.5)^{5}.(0.5)^{3} = 0.2188[/tex]
[tex]P(X = 6) = C_{8,6}.(0.5)^{6}.(0.5)^{2} = 0.1094[/tex]
[tex]P(X = 7) = C_{8,7}.(0.5)^{7}.(0.5)^{1} = 0.0313[/tex]
[tex]P(X = 8) = C_{8,8}.(0.5)^{8}.(0.5)^{0} = 0.0039[/tex]
[tex]P(X \geq 5) = P(X = 5) + P(X = 6) + P(X = 7) + P(X = 8) = 0.2188 + 0.1094 + 0.0313 + 0.0039 = 0.3634[/tex]
0.3634 = 36.34% probability that the Wilson family had at least 5 girls.
At most 5 girls?
This is:
[tex]P(X \leq 5) = 1 - P(X > 5)[/tex]
In which
[tex]P(X > 5) = P(X = 6) + P(X = 7) + P(X = 8) = 0.1094 + 0.0313 + 0.0039 = 0.1446[/tex]
[tex]P(X \leq 5) = 1 - P(X > 5) = 1 - 0.1446 = 0.8554[/tex]
0.8554 = 85.54% probability that the Wilson family had at most 5 girls.
An adult has a total of about 22.6 square feet (ft2) of skin. Use the fact that 1 m is approximately equal to 3.281 feet to convert this measurement to square meters (m2).
Answer:
2.09 square meters.
Step-by-step explanation:
There are about 3.281 * 3.281 = 10.764 square feet in one square meter. Therefore, 22.5 square feet is 22.5 / 10.764 = 2.09 square meters.
Under his cell phone plan, Alexander pays a flat cost of $69.50 per month and $5 per gigabyte. He wants to keep his bill under $85 per month. Write and solve an inequality which can be used to determine gg, the number of gigabytes Alexander can use while staying within his budget.
Answer:
3 gigabytes
Step-by-step explanation:
69.50 dollars + 5 dollars is 74.50 dollars add 5 dollars 79.50 add 5 dollars again and 84.50 Mark brainliest
Inequalities help us to compare two unequal expressions. Alexander can use 3 gigabyte of data to stay within his budget.
What are inequalities?Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.
Given that Alexander pays a flat cost of $69.50 per month and $5 per gigabyte. Therefore, the total amount that Alexander pays in a month for x Gb of data used is,
Total Bill amount = Fixed cost + Variable cost for x Gb of data
= $69.50 + $5x
Now, as Alexander wants to keep his bill under $85 per month. Therefore, we can write the inequality as,
Total Bill amount < $85
69.50 + 5x < 85
5x < 85 - 69.50
5x < 15.5
x < 15.5/5
x < 3.1
Therefore, Alexander can use 3 gigabyte of data to stay within his budget.

Considering that we want to test if the support for the opponent has decreased, the appropriate set of hypotheses for their significance test is given by:
C.
[tex]H_0: p = 0.45[/tex]
[tex]H_1: p < 0.45[/tex]
What are the hypothesis tested?At the null hypothesis, we test if the support for the opponent has not decreased, that is, it still is of 45%, hence:
[tex]H_0: p = 0.45[/tex]
At the alternative hypothesis, we test if the support has decreased, that is, it is less than 45%, hence:
