Answer:
Rectangle Y.
Step-by-step explanation:
Find the perimeter of both rectangles.
If you want to find rectangle X, the breadth of the rectangle but the length of it isn't the same since it has been shortened, and since it covers half of the card for length...
Length = 14 ÷ 2 = 7cm
Perimeter = 6cm + 6cm + 7cm + 7cm = 26cm (Rectangle X)
Now, let's find perimeter for rectangle Y.
The length for the rectangle is the same as it isn't shortened or anything else, but the breadth is different as it have been shortened, since it covers half of the card for breadth...
Breadth = 6 ÷ 2 = 3cm
Perimeter = 3cm + 3cm + 14cm + 14cm = 34cm
(Rectangle Y)
Explaination: Rectangle Y will have the longer perimeter, (add in the solution that I wrote for rectangle X and Y)

ABC is a right triangle. If AC=4 and BC=10, find AB. Leave your answer is the simplest radical form.
Answers
Answer:
√116 or √84Step-by-step explanation:
ABC is a right triangle
AC=4, BC=10, AB = ?Here we have two options:
1. AB is hypotenuse, then:
AB = [tex]\sqrt{AC^2 + BC^2} = \sqrt{4^2 + 10^2} = \sqrt{16 + 100} =\sqrt{116}[/tex]2. BC is hypotenuse and AB is the second leg, then:
AB = [tex]\sqrt{BC^2 - AC^2} = \sqrt{10^2 - 4^2} = \sqrt{100 - 16} = \sqrt{84}[/tex]$72 game with a 20% discount and 7.5% tax
Answers
Answer:
Cost of game after discount = 72 - 20% of 72 = $57.6
Cost after tax = 57.6 + 7.5% of 57.6 = $61.92
So, the required cost is $61.92.

Use the drawing tools to graph the solution to this system of inequalities on the coordinate plane.
y> 2x + 4
x+y s6
Answers
The inequalities y > 2x + 4 and x + y ≤ 6 can be plotted on the coordinate plane as shown in the picture.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
We have two inequalities:
y > 2x + 4
x + y ≤ 6
We can plot the above inequality on the coordinate plane.
The inequalities representing the region between the two lines the lines are:
y = 2x + 4
x + y = 6
y > 2x + 4 (dashed line on the graph)
x + y ≤ 6 (solid line on the graph)
Thus, the inequalities y > 2x + 4 and x + y ≤ 6 can be plotted on the coordinate plane as shown in the picture.

Suppose that 65% of high school students eat breakfast before going to school. A random sample of 500 high school students were surveyed. Let X = the number of high school students in a random sample of size 500 who eat breakfast before going to school.
1. Explain why X can be modeled by a binomial distribution even though the sample was selected without replacement.
2. Use a binomial distribution to estimate the probability that 300 or fewer high school students in the sample eat breakfast before going to school.
3. Justify why X can be approximated by a Normal distribution.
4. Use a Normal distribution to estimate the probability that 300 or fewer high school students in the sample eat breakfast before going to school.
Answers
Answer:
1.) very large sample size
2.) 0.11326
3.) np and n(1-p) should be ≥ 10
4.) 0.010809
Step-by-step explanation:
Given :
p = 0.65 ; n = 500
2.)
P(x ≤ 300)
P(x =x) = nCx * p^x * (1 - p)^(n - x)
Using a binomial probability calculator :
P(x ≤ 300) = 0.11326
To justify why if it can be approximated using a normal distributon :
np and n(1-p) should be ≥ 10
np = 500 * 0.65 = 325
n(1-p) = 500(1 - 0.65) = 175
4.) probability using normal distribution estimate:
Mean, m = np = 500 * 0.65 = 325
Standard deviation, s = sqrt(n*p*(1-p)) = sqrt(500*0.65*(1 - 0.65)) = sqrt(113.75) = 10.665
x ≤ 300
Correction:
x = x + 0.5 = 300 - 0.5 = 300.5
P(x ≤ 300.5)
Zscore = (x - m) / s
Zscore = (300.5 - 325) / 10.665
Zscore = - 24.5 / 10.665
Zscore = - 2.297
P(Z ≤ - 2.297) = 0.010809
X can be modeled by a binomial distribution even though the sample was selected without replacement because the sample size is too large, and the probability that 300 or fewer high school students in the sample eat breakfast before going to school is 0.010809.
Given :
Suppose that 65% of high school students eat breakfast before going to school. A random sample of 500 high school students was surveyed. Let X = the number of high school students in a random sample of size 500 who eat breakfast before going to school.1) X can be modeled by a binomial distribution even though the sample was selected without replacement because the sample size is too large.
2) The formula for the binomial distribution is given by:
[tex]\rm P (x=x)= \; ^nC_x \times p^x \times (1-p)^{n-x}[/tex]
Now, substitute the known terms in the above formula.
[tex]\rm P (x\leq 300)= \; ^{500}C_x \times (0.65)^x \times (1-0.65)^{500-x}[/tex]
Simplify the above expression.
[tex]\rm P(x \leq 300)=0.11326[/tex]
3) Now, the value of np and n(1 - p) is given below:
np = 500 [tex]\times[/tex] 0.65 = 325
n(1 - p) = 500 [tex]\times[/tex] (1 - 0.65) = 175
X can be approximated by a Normal distribution because the value of np and n(1 - p) is greater than or equal to 10.
4)
First, determine the standard deviation.
[tex]\rm \sigma = \sqrt{np(1-p)}[/tex]
[tex]\rm \sigma = \sqrt{500\times 0.65 \times (1-0.65)}[/tex]
[tex]\rm \sigma = 10.665[/tex]
Now, the z-score can be calculated by using the formula:
[tex]\rm z =\dfrac{X-\mu}{\sigma}[/tex]
[tex]\rm z =\dfrac{300.5-325}{10.665}[/tex]
z = -2.297
So, the probability that 300 or fewer high school students in the sample eat breakfast before going to school is given by:
[tex]\rm P(Z\leq -2.297) = 0.010809[/tex]

Two pencils and a ruler cost 98 cents in total. One pencil and 2 rulers cost $1.24 in total. Find the cost of each item.
Answers
Answer:
2.16
Step-by-step explanation:
r = cost of ruler
p = cost of pencil
r = 2p
6r + 15p = 2.16
Substitute 2p in place of r in 2nd equation and solve for p
6(2p) + 15p = 2.16
12p + 15p = 2.16
27p = 2.16
6(2p)+15p=2.16
12p+15p=2.16
27p=2.16

Work out the total cost of the holiday for 4 people for 7 days.
Answers
Answer:
£3,800
Step-by-step explanation:
The computation of the total cost is shown below;
Each person cost is
Travel cost £250 (assume for 7 days)
Hotel cost £50 × 7 days = £350
Spending money £350 (assume for 7 days)
Cost for each person is £950
Since there are four persons, so the total cost would be
= £950 × 4 peoples
= £3,800

10th term of the sequence = 0.537
Step-by-step explanation:
First three terms of the sequence are → 5, 4, [tex]\frac{16}{5}[/tex]..........
Ratio of 2nd and 1st term of the sequence = [tex]\frac{4}{5}[/tex]
Ratio of 3rd and 2nd term of the sequence = [tex]\frac{\frac{16}{5} }{4}[/tex]
= [tex]\frac{4}{5}[/tex]
Therefore, ratio between every successive term to the previous term is common.
Common ratio 'r' = [tex]\frac{4}{5}[/tex]
First term of the sequence 'a' = 5
nth term of a geometric sequence = [tex]a(r)^n[/tex]
Therefore, nth term of the given term will be [tex]T_n=5(\frac{4}{5})^n[/tex]
Now we have to find the 10 term of the given sequence.
For n = 10,
[tex]T_{10}=5(\frac{4}{5})^{10}[/tex]
= 0.53687
≈ 0.537
Therefore, 10th term of the sequence is 0.537
