Triangle ABC is reflected over the x-axis. What are the coordinates of the image of the vertex A?
A. A’(2, 5)
B. A’(-2, 5)
C. A’(5, -2)
D. A’(2, -5)
Answer:
D. A'(2, -5)
Step-by-step explanation:
Since point A is at (2, 5), and you are reflecting it across the x-axis, you take a look at the y-coordinate. Since it is five above the x-axis, you go five below the x-axis, or just give the OPPOSITE of 5, which is -5.
So, A' is at (2, -5).
I am delighted to assist you anytime.
When point A(2, 5) is reflected over the x-axis, its y-coordinate becomes -5 while the x-coordinate remains the same, resulting in the image point A'(2, -5).
The correct answer is option B.
When a point is reflected over the x-axis, its y-coordinate changes sign while the x-coordinate remains the same.
Let's apply this reflection to point A(2, 5):
Original point A(2, 5) has an x-coordinate of 2 and a y-coordinate of 5. When reflected over the x-axis, the x-coordinate remains 2, but the y-coordinate changes sign to -5. Therefore, the image of point A after the reflection is A'(2, -5).
So, the correct answer is:
D. A’(2, -5)

A batch consists of 12 defective coils and 88 good ones. Find the probability of getting two good coils when two coils are randomly selected if the first selection is replaced before the second is made. 0.7744 0.7733 0.0144 0.176
Answer:
The probability of getting two good coils when two coils are randomly selected if the first selection is replaced before the second is made is 0.7744
Solution:
Total number of coils = number of good coils + defective coils = 88 + 12 = 100
p(getting two good coils for two selection) = p( getting 2 good coils for first selection ) [tex]\times[/tex] p(getting 2 good coils for second selection)
p(first selection) = p(second selection) = [tex]\frac{\text { number of good coils }}{\text { total number of coils }}[/tex]
Hence, p(getting 2 good coil for two selection) = [tex]\frac{88}{100} \times \frac{88}{100} =\bold{0.7744}[/tex]
Probability of selecting two good coils with replacement: [tex]\(0.88 \times 0.88 = 0.7744\)[/tex]. Correct answer is D) 0.7744.
To solve this problem, we need to calculate the probability of selecting two good coils when the first selection is replaced before the second is made. This means the selections are independent.
Here are the steps:
1. Calculate the total number of coils:
12 defective +88 good $=100$ total
2. Determine the probability of selecting a good coil on the first draw:
[tex]\[ P(\text{good on first draw}) = \frac{88}{100} = 0.88 \][/tex]
3. Since the first coil is replaced, the probability of selecting a good coil on the second draw is the same:
[tex]\[ P(\text{good on second draw}) = \frac{88}{100} = 0.88 \][/tex]
4. Calculate the probability of both events (selecting two good coils):
[tex]\[ P(\text{two good coils}) = P(\text{good on first draw}) \times P(\text{good on second draw}) \][/tex]
[tex]\[ P(\text{two good coils}) = 0.88 \times 0.88 = 0.7744 \][/tex]
Therefore, the probability of getting two good coils when two coils are randomly selected with replacement is:
[tex]\[\boxed{0.7744}\][/tex]
So the correct answer is:
D) 0.7744
The correct question is:
A batch consists of 12 defective coils and 88 good ones. Find the probability of getting two good coils when two coils are randomly selected if the first selection is replaced before the second is made.
A) 0.176
B) 0.0144

What is the 30th term of the linear sequence below?
-4, -1,2,5,8,...
Answer:
The 30th term is 83
Step-by-step explanation:
we know that
An arithmetic sequence is a sequence of numbers such that the difference of any two successive members of the sequence is a constant called the common difference d
in this problem
[tex]a_1=-4\\a_2=-1\\a_3=2\\a_4=5\\a_5=8[/tex]
so
[tex]a_2-a_1=-1-(-4)=3\\a_3-a_2=-2-(-1)=3\\a_4-a_3=-5-2=3\\a_5-a_4=-8-5=3[/tex]
The common difference d is 3
We can write an Arithmetic Sequence as a rule:
[tex]a_n=a_1+d(n-1)[/tex]
Find out the 30th term
we have
[tex]n=30\\d=3\\a_1=-4[/tex]
substitute
[tex]a_n=-4+(3)(30-1)[/tex]
[tex]a_n=-4+(3)(29)[/tex]
[tex]a_n=83[/tex]
Final answer:
The 30th term of the linear sequence is 83, found using the formula for the nth term of a linear sequence an = a1 + (n - 1)d, with a common difference of 3.
Explanation:
To find the 30th term of the linear sequence given by -4, -1, 2, 5, 8,..., first identify the common difference between consecutive terms. In this sequence, each term increases by 3. So, the common difference (d) is 3.
To find the nth term of a linear sequence, use the formula:
an = a1 + (n - 1)d, where
an is the nth term,
a1 is the first term, and
d is the common difference.
For our sequence:
a1 = -4 (the first term),
d = 3,
n = 30 (since we are finding the 30th term).
Plugging into the formula gives:
a30 = -4 + (30 - 1) × 3
a30 = -4 + 29 × 3
a30 = -4 + 87
a30 = 83
Therefore, the 30th term of the sequence is 83.
How to solve a+5=-5a+5
The solution to the equation a+5=-5a+5 is a=0.
We are given that;
The expression a+5=-5a+5
Now,
To solve the equation a+5=-5a+5, we need to isolate the variable a on one side of the equation.
We can do this by adding 5a to both sides of the equation:
a + 5 + 5a = -5a + 5 + 5a
Combining like terms gives:
6a + 5 = 5
Subtracting 5 from both sides of the equation gives:
6a = 0
Dividing both sides of the equation by 6 gives:
a = 0
Therefore, by algebra the answer will be a=0.

What is 21=6r+5-7r someone please help thank you
Answer:
r=-16
Step-by-step explanation:
21=6r+5-7r
1) Combine alike terms on the right side (6r and -7r):
21=-r+5
2) Subtract a 5 from both sides:
16=-r
3) Divide both sides by -1:
r=-16
Step-by-step explanation:
first combine like terms : 6r and -7r = -1r
21=5 -1r
cancellation cancel the same terms on both sides of the equation by inverse operations:
subtract 5 from both sides 21-5= 16 5-5=0
16=-1r
divide both ends of the equation by -1
16÷1 = 16 1÷ -1= 1
16=r
Fernando invested money in a 3–yr CD (certificate of deposit) that returned the equivalent of 3.8% simple interest. He invested $1000 less in a 6–month CD that had a 2% simple interest return. If the total amount of interest from these investments was $424.00, determine how much was invested in each CD.
Answer:
The amount invested at 3–yr CD was $3,600 and the amount invested at 6–month CD was $2,600
Step-by-step explanation:
Let
x -----> the amount invested at 3–yr CD
x-$1,000 ----> the amount invested at 6–month CD
we know that
The simple interest formula is equal to
[tex]I=P(rt)[/tex]
where
I is the Final Interest Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
3–yr CD
[tex]t=3\ years\\P=x\\r=0.038[/tex]
substitute in the formula above
[tex]I1=x(0.038*3)[/tex]
[tex]I1=0.114x[/tex]
6–month CD
[tex]t=6/12=0.5\ years\\P=x-1,000\\r=0.02[/tex]
substitute in the formula above
[tex]I2=(1,000-x)(0.02*0.5)[/tex]
[tex]I2=10-0.01x[/tex]
Remember that
the total amount of interest from these investments was $424.00
so
[tex]I1+I2=424[/tex]
substitute and solve for x
[tex]0.114x+10+0.01x=424[/tex]
[tex]0.115x=414[/tex]
[tex]x=\$3,600[/tex]
[tex]x-\$1,000=\$2,600[/tex]
therefore
The amount invested at 3–yr CD was $3,600 and the amount invested at 6–month CD was $2,600
Bryan took a taxi home from the opera. The taxi fare was $2.50 per mile, and he gave the driver a tip of $3. Bryan paid a total of $35.50. The equation 2.50x + 3 = 35.5 can be used to find the distance in miles (x) between the opera house and Bryan's home.
How many miles is it between the opera house and Bryan's home?
Answer:
There are 13 miles between the opera house and Bryan's home.
Step-by-step explanation:
The equation [tex]2.50x+3=35.5[/tex] can be used to find the distance in miles (x) between the opera house and Bryan's home.
We will solve this to get the value of x.
[tex]2.50x+3=35.5[/tex]
=> [tex]2.50x=35.5-3[/tex]
=> [tex]2.50x=32.50[/tex]
we get x = 13
Hence, there are 13 miles between the opera house and Bryan's home.

The race speeds for the top eight cars in a 200-mile race are listed below. Use the range rule of thumb
to estimate the standard deviation. Round results to the nearest tenth.
185.9 179.5 189.2 176.7 1758 188.7. 188.3 177.9
Answer:The standard deviation is about 3.6.
Step-by-step explanation:
According to the Range Rule of Thumb : The range is about four times the standard deviation.
i.e. [tex]R\approx4\sigma\Rightarrow\ \sigma\approx\dfrac{R}{4}[/tex] (i)
Given , The race speeds for the top eight cars in a 200-mile race are :
185.9 179.5 189.2 176.7 175.8 188.7. 188.3 177.9
Here , minimum speed = 175.8 and maximum speed = 189.2
Range = maximum speed - minimum speed
i.e. R = 189.2-175.8 =13.4
from (i),
[tex]\sigma\approx\dfrac{13.4}{4}\\\\\Rightarrow\sigma\approx3.6[/tex]
Hence, the standard deviation is about 3.6.
