Answer:
$7.28
Step-by-step explanation:
We have been given that Brandon buys a basket of flowers for $7 before tax. The sales tax is 4%.
The total price that Brandon paid for the basket of flowers will be equal to 7 plus 4% of 7.
We can represent this information in an equation as:
[tex]\text{The total price that Brandon paid for the basket of flowers}=7+(\frac{4}{100}\times 7)[/tex]
[tex]\text{The total price that Brandon paid for the basket of flowers}=7+(0.04\times 7)[/tex]
[tex]\text{The total price that Brandon paid for the basket of flowers}=7+0.28[/tex]
[tex]\text{The total price that Brandon paid for the basket of flowers}=7.28[/tex]
Therefore, the total price paid by Brandon for the basket of flowers was $7.28.
Answer:
Total price Brandon pays for the basket of flowers is, $7.28
Step-by-step explanation:
As per the given statement: Brandon buys a basket of flowers for $7 before tax.
Convert this $7 into cents.
1 dollars = 100 cents.
$7 = 700 cents.
It is also given that the sales tax is 4%.
then;
Sales tax = [tex]4\% \times 700 = \frac{4}{100} \times 700 = 4 \times 7 =28 cents[/tex]
Total price Brandon pays = Price of Brandon buys a flower before tax + sales tax price
= 700 + 28 = 728 cents = $7.28
Therefore, the total price Brandon pays for the basket of flowers is, $7.28
To determine whether there is a relationship between the type of school attended and verbal reasoning scores for Irish students, three samples with 25 students, in each group, were randomly selected from data used by Raferty and Hout (1985). One group of students attended secondary school, the second group of students attended vocational school, and the third group consisted of students who attended only primary school.
Select one answer.
If we let μ1, μ 2, and μ 3 be the mean verbal reasoning scores for students who attended secondary school, vocational school, and primary school only, respectively, the appropriate hypotheses in this case are:
a. H0: μ1 = μ2 = μ3
Ha: μ1, μ2, μ3, are not all equal
b. H0: μ1, μ2, μ3, are not all equal
Ha: μ1 = μ2 = μ3
c. H0: μ1 = μ2 = μ3
Ha: μ1 μ μ2 μ μ3
d. H0: μ1 μ μ2 μ μ3
Ha: μ1 = μ2 = μ3
e. None of the above are correct.
The correct hypotheses are:
b. [tex]\(H_0: \mu_1 = \mu_2 = \mu_3\) and \(H_a: \mu_1, \mu_2, \mu_3\) are not all equal.[/tex]
To determine the appropriate hypotheses for testing the relationship between the type of school attended and verbal reasoning scores for Irish students, we first need to understand the nature of the comparison being made.
We have three groups of students: those who attended secondary school, vocational school, and primary school only. We want to investigate if there is a difference in the mean verbal reasoning scores among these groups.
The null hypothesis [tex](\(H_0\)) states that there is no difference in the mean verbal reasoning scores among the three types of schools, expressed as \( \mu_1 = \mu_2 = \mu_3 \), where \( \mu_1 \), \( \mu_2 \), and \( \mu_3 \)[/tex] are the population means for students attending secondary school, vocational school, and primary school only, respectively.
The alternative hypothesis [tex](\(H_a\)) suggests that at least one of the population means is different from the others, expressed as \( \mu_1, \mu_2, \mu_3 \)[/tex] are not all equal.
Option b correctly represents these hypotheses:
[tex]\(H_0: \mu_1 = \mu_2 = \mu_3\) \(H_a: \mu_1, \mu_2, \mu_3\) are not all equal.[/tex]
This formulation allows for the testing of differences in mean verbal reasoning scores across the three types of schools. The null hypothesis assumes equality among the means, while the alternative hypothesis considers the possibility of inequality.

If JK and LM are congruent and parallel, then JKL and MLK are congruent.
True
False
Answer:
TRUE
Step-by-step explanation:
Given that line segment JK and LM are parallel. From picture we see that LK is transversal line.
We know that corresponding angles formed by transversal line are congruent.
Hence ∠JKL = ∠ MLK ...(i)
Now consider triangles JKL and MLK
JK = LM {Given}
∠JKL = ∠ MLK { Using (i) }
KL = KL {common sides}
Hence by SAS property of congruency of triangles, ΔJKL and ΔMLK are congurent.
Hence given statement is TRUE.
The statement that if JK and LM are congruent and parallel, then angles JKL and MLK are congruent is false. Congruency of angles depends on more than just the congruency and parallelism of two lines.
Explanation:In the field of geometry, just because two lines are congruent and parallel, this does not necessarily mean that the angles formed by the intersection of the lines with a third line are congruent. The statement 'If JK and LM are congruent and parallel, then JKL and MLK are congruent' is false. Congruency of angles JKL and MLK depends on the relationship between the two other sides of the angles, not solely the lines JK and LM. Therefore, for the angles to be congruent, additional conditions besides the congruency and parallelism of JK and LM must be satisfied.

There were 200 people who voted at the Town council meeting all these people 40% voted for a new basketball court in the park how many people voted against building a new basketball court use numbers in words to explain your answer
Answer:
120 people voted against building the new basketball court.
Step-by-step explanation:
if you divide 200 by 100 then you know how many people equal 1 percent of the 200. knowing that for every 2 people they are equal to 1 percent. so if you do 100 -40 you get 60. the 100 represents the 100 percent and you subtract 40 because these are the people who are voting for the basketball court. The 60 represents the percent of people who are voting against building the basketball court. then you multiply 60 by 2 and you get 120.

A jet ski company charges a flat fee of $26 plus $3.25 per hour to rent a jet ski another company charges a fee of $24 plus $3.50 per hour to rent the same jet ski find number of hours for which the cost are the same round your number to the nearest whole hour
Answer: 8 hours
Step-by-step explanation:
Company 1: 3.25x + 26
Company 2: 3.50x + 24
3.50x + 24 = 3.25x + 26
0.25x +24 = 26 subtracted 3.25x from both sides
0.25x = 2 subtracted 24 from both sides
x = 8 divided both sides by 0.25
Check:
Company 1: 3.25x + 26 = 3.25(8) + 26 = $52
Company 2: 3.50x + 24 = 3.50(8) + 24 = $52
Compare the volume of a square pyramid to the volume of a square prism with the same base and height as the pyramid.
Answer:
The Volume of the square pyramid is 1/3 the volume of a square prism with the same base and height
Step-by-step explanation:

a flying object's height in the sky can be represented by the equation d= 30+vt+[tex]4t^2\\[/tex] where d is the height in feet, v is the velocity in feet per second, and t is the time in seconds. how long has the flying object been traveling if it has a velocity of 8 feet per second and has risen to a height of 126 ft?
a). 4 seconds
b). 6 seconds
c). 8 seconds
d). 16 seconds
Answer:
t=4 seconds
Step-by-step explanation:
The equation given to us is
d=30 + vt + 4t²
d=126 feet
v= 8 ft per second
to find t =?
Now putting the values in the above equation gives
126 = 30 + 8t + 4t²
126 - 30 = 8t + 4t²
96 = 8t + 4t²
Dividing the whole equation by 4
[tex]\frac{96}{4}=\frac{8t}{4}+\frac{4t^{2} }{4}[/tex]
it will become
24 = 2t + t²
taking 24 to other sides of equality
0 = 2t + t² -24
t²+2t-24=0
Now we will do mid term breaking of the eqaution
t²+6t-4t-24=0
taking common from the equation
t(t+6)-4(t+6)=0
(t+6)(t-4)=0
so it becomes
t+6 = 0 or t-4 =0
t =-6 or t = 4 seconds
as time can not be negative
so t=4 seconds

In a fruit punch drink the 3 ingredients are apple juice orange juice and cranberry juice. If 1/4 of the drink is apple juice and 2/5 is orange juice then write the ratio of cranberry juice to apple juice to orange juice in its simplest form.
Answer: The required ratio in simplest form is 7 : 5 : 8.
Step-by-step explanation: Given that in a fruit punch drink, the 3 ingredients are apple juice orange juice and cranberry juice. [tex]\frac{1}{4}[/tex] of the drink is apple juice and [tex]\frac{2}{5}[/tex] is orange juice.
We are to find the ratio of cranberry juice to apple juice to orange juice in its simplest form.
Let x, y and z be the fractions of the cranberry juice, apple juice and orange juice in the fruit punch drink.
Then, according to the given information, we have
[tex]y=\dfrac{1}{4},~~z=\dfrac{2}{5}.[/tex]
Now,
[tex]x+y+z=1\\\\\\\Rightarrow x+\dfrac{1}{4}+\dfrac{2}{5}=1\\\\\\\Rightarrow x=1-\dfrac{1}{4}-\dfrac{2}{5}\\\\\\\Rightarrow x=\dfrac{20-5-8}{20}\\\\\\\Rightarrow x=\dfrac{7}{20}.[/tex]
Therefore, the ratio of cranberry juice to apple juice to orange juice is given by
[tex]x:y:z\\\\\\=\dfrac{7}{20}:\dfrac{1}{4}:\dfrac{2}{5}\\\\\\=\dfrac{7}{20}:\dfrac{5}{20}:\dfrac{8}{20}\\\\=7:5:8.[/tex]
Thus, the required ratio in simplest form is 7 : 5 : 8.
