Answer:
D. rectangle
Step-by-step explanation:
The slopes of 2 lines are perpendicular when they are the negative reciprocal of each other. In this case, that is true, because 3 is the negative reciprocal of -1/3 and vice versa. This means it's either a rectangle or a square.
The lengths of the lines are not all the same, meaning it cannot be a square.
Therefore, the best name for the quadrilateral MATH is rectangle.

Jenna works in an ice cream shop. When she starts her shift the tub of chocolate ice cream is 2/3 full. When she finishes her shift 6 1/2 h later, there is only 1/6 of the tub left. What was the average hourly change in tub fullness?
IMMEDIATE PLEASE.
Answer:
[tex]-1/13\text{ tub per hour}[/tex]
Step-by-step explanation:
First, let's find how much of the tub was used within the time.
We know that the tub was 2/3 full was Jenna started.
And it was only 1/6 full when Jenna ended.
Therefore, to find the amount used, we can subtract 1/6 from 2/3. So:
[tex]u=\frac{2}{3}-\frac{1}{6}[/tex]
Make a common denominator. Change 2/3 to 4/6 by multiplying both layers by 2. So:
[tex]u=\frac{4}{6}-\frac{1}{6}[/tex]
Subtract and reduce:
[tex]u=\frac{3}{6}=\frac{1}{2}[/tex]
Therefore, 1/2 of the tub was used after 6 1/2 hours.
To find the average hourly change, we will put the amount used over the amount of hours. 6 and 1/2 hours is the same as 13/2 hours. Therefore, the hourly change will be:
[tex]c=\frac{\frac{1}{2}}{\frac{13}{2}}[/tex]
Remember when dividing fractions, we:
1) Flip the divisor (the second number).
2) Change the division sign to a multiplication sign.
3) Multiply.
So:
[tex]c=\frac{1}{2}\div\frac{13}{2}\\\Rightarrow c=\frac{1}{2}\times \frac{2}{13}[/tex]
Multiply straight across and reduce:
[tex]c=\frac{2}{26}=\frac{1}{13}[/tex]
However, since we are using up the tub, our rate will be negative. Therefore:
[tex]c=-\frac{1}{13}[/tex]
Therefore, the average hourly rate was -1/13 tub per hour.
This means that after each hour, 1/13 of the tub will be used up.
Edit: Corrected Wrong Answer
Answer: -1/13 of a tub per hour
Step 1: Subtract.
2/3 - 1/6 = ?
Step 2: Find the common denominator.
4/6 - 1/6 = 3/6.
Step 3: Simplify the fraction.
3/6 = 1/2
Step 4: Put 1/2 over 13/2.
1/2 over 13/2
Step 5: Flip divisor around. Then divide.
1/2 ÷ 13/2
Step 6: Multiply.
1/2 × 2/13 = 2/26.
2/26 reduced = 1/13.
Since it was used, now it is -1/13
Answer = -1/13 of a tub per hour

Answer:
9x-4
Step-by-step explanation:
Add 3x and 6x hope it help
Answer:
9x - 4
Step-by-step explanation:
3x + 6x - 4
First, combine like terms, so you would add 3x and 6x together to form 9x
9x - 4
Because you cannot simplify this equation any more, that is the answer

Answer:
1.49 x [tex]10^{5}[/tex] hours
Step-by-step explanation:
1 day=24hours
1 year=365 days
365days=24 x 365=8760hours
17 years
= 8760hours x 17
=148920hours
=1.4892 x [tex]10^{5}[/tex]
= 1.49 x [tex]10^{5}[/tex] hours
Answer:
1.49 x hours
Step-by-step explanation:
1 day=24hours
1 year=365 days
365days=24 x 365=8760hours
17 years
= 8760hours x 17
=148920hours
=1.4892 x
= 1.49 x hours

Refer to the data set of 20 randomly selected presidents given below. Treat the data as a sample and find the proportion of presidents who were taller than their opponents. Use that result to construct a 95% confidence interval estimate of the population percentage. Based on the result, does it appear that greater height is an advantage for presidential candidates? Why or why not?
Complete Question
The data for this question is shown on the first uploaded image
Answer:
The 95% confidence interval estimate of the population percentage is
[tex] 33.2\% < p < 76.8 \% [/tex]
Step-by-step explanation:
On the data the first value is the height of the president while the other value is the height of his opponent
The sample size is n = 20
Looking at the data we see that out of the 20 presidents that only 11 is taller than their opponent
So the proportion of presidents that are taller than their opponents is
[tex]\^ p = \frac{11}{20}[/tex]
=> [tex]\^ p = 0.55[/tex]
From the question we are told the confidence level is 95% , hence the level of significance is
[tex]\alpha = (100 - 95 ) \%[/tex]
=> [tex]\alpha = 0.05[/tex]
Generally from the normal distribution table the critical value of is
[tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \sqrt{\frac{\^ p (1- \^ p) }{n}} [/tex]
[tex]E = 1.96 * \sqrt{\frac{0.55 (1- 0.55) }{20}} [/tex]
[tex]E = 0.218[/tex]
Generally 95% confidence interval is mathematically represented as
[tex]\r p -E < p < \r p +E[/tex]
=> [tex]0.55-0.218 < p < 0.55+ 0.218 [/tex]
=> [tex]0.332 < p < 0.768 [/tex]
Converting to percentage
[tex](0.332*100)\% < p < (0.768 *100) \% [/tex]
=> [tex] 33.2\% < p < 76.8 \% [/tex]

Step-by-step explanation:
Taiga’s teacher asked him to draw a polygon with vertices (–4, –5), (–5, 2), (–5, 3), (–4, 5), (2, 3), and (–3, 0) and to identify the polygon. Taiga drew the polygon below and identified it as a heptagon. On a coordinate plane, points are at (negative 4, negative 5), (negative 5, 2), (negative 5, 3), (negative 4, 5), (2, 3), and (negative 3, 0). Which explains whether Taiga is correct? Taiga is correct because the polygon has six sides. Taiga is correct because the sides have different lengths. Taiga is not correct because the polygon is a hexagon. Taiga is not correct because he drew the polygon incorrectly.
