PLEASE HELP!!!!

Mathematics
1 answer:
3241004551 [841]2 years ago
3 0

Answer: Correct

Step-by-step explanation:

The conclusion is valid. Since \overline{AB} \parallel \overline{DC} and \overline{AD} \parallel \overline{BC}, we know that ABCD is a parallelogram because it has two pairs of parallel sides. Also, since \overline{AB} \cong \overline{BC}, we know that ABCD is a parallelogram with a pair of consecutive congruent sides, making it a rhombus.

Y=-3x+5<br> 5x-4y=-3<br> pls help
salantis [7]

Hello!

\large\boxed{x = 1, y = 2}

We can solve this system using substitution.

Since y = -3x + 5, we can substitute this into the following equation:

5x - 4(-3x + 5) = -3

Simplify:

5x - 4(-3x) - 4(5) = -3

5x + 12x - 20 = -3

Combine like terms:

17x - 20 = -3

Add 20 to both sides:

17x = 17

x = 1

Substitute to find y:

y = -3(1) + 5

y = -3 + 5

y = 2

Solution: (1, 2)

Kristen Ashford purchased the subscribers list for Wind Surfing magazine. She plans to survey a sample of the subscribers before
vagabundo [1.1K]

Answer:

The correct option is d) convenience sample

Step-by-step explanation:

In statistics, we use different sampling techniques to gather a chunk of sample data from a very large population.

There are many sampling techniques and out of them one is convenience sampling.

Convenience Sampling:

The convenience sampling is defined as the sample data which is readily and conveniently available.

Examples:

1. Asking people questions at a place that is convenient for you.

2. Asking your friends or family members

3. A college student asking for student's opinion at the college who is surveying for his thesis.

In the given scenario, Kristen Ashford has list of 5,000 subscribers for Wind Surfing magazine. She chooses the first 100 of the 5,000 names, this is clearly a convenient sample since the sample is easily, readily and conveniently available.

If she had selected 100 names randomly then it would have been called random sampling but in this case, she simply selected the first 100 names for the sake of convenience therefore, it is a convenience sample.

Two planes leave an airport at the same​ time, one flying​ east, the other flying west. The eastbound plane travels 130 mph slow
Art [367]

Answer:

Speed of the slower plane = 320 mph

Speed of the faster plane = 450 mph

Step-by-step explanation:

Let the speed of the slower plane = x mph

And the speed of the faster plane = y mph

Difference in their speeds = 130 mph

y - x = 130 --------(1)

Formula for the distance traveled = Speed × time

Distance traveled by the faster plane in 5 hours = 5y miles

Distance traveled by the slower plane in 5 hours = 5x miles

Total distance traveled by both the planes in 5 hours = 5(x + y) miles

5(x + y) = 3850

x + y = 770 ---------(2)

By adding equations (1) and (2)

2y = 900

y = 450 mph

From equation (2)

x = 770 - 450

x = 320 mph
