Answer 1

Answer:

Step-by-step explanation:

1). Swap the order of equations.

2). Yes, system of equations are equivalent with the same solution.

29x = 46 ⇒ x = [tex]\frac{46}{29}[/tex]

y = - [tex]\frac{184}{29}[/tex] + [tex]\frac{203}{29}[/tex] = [tex]\frac{19}{29}[/tex]

( - [tex]\frac{46}{29}[/tex] , [tex]\frac{19}{29}[/tex] )

Which is the best estimate of each percent?

21% of 387
a
80
b
8
c
800
d
0.8

Answers

Answer:

a. 80

Step-by-step explanation:

For the best estimate consider close numbers:

20% is close to 21% and 400 is close to 387

20% of 400 is

0.2*400 = 80

So option a. 80 is correct

The coordinate of the z² will be (4, 1) which is represented by point D. Then the correct option is D.

What is coordinate geometry?

Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.

The coordinate of the z will be given from the graph.

The coordinate of z is (2, 1).

If the square is of z is done, then the coordinate of the z² will be

z ⇒ (2, 1)

z² ⇒ (2, 1)²

z² ⇒ (2², 1²)

z² ⇒ (4, 1)

The coordinate of the z² will be (4, 1) which is represented by point D.

Then the correct option is D.

Step-by-step explanation:

A nationwide poll asked a random sample of US adults the question, “Are you in favor of making Election Day a federal holiday?” Based on the results of this poll, the 95% confidence interval for the population proportion who favor making Election Day a federal holiday is (0.64, 0.70).

Calculate the point estimate and margin of error for the given confidence interval.

Enter both values to 2 decimal places.

The point estimate =

The margin of error =

Answers

Answer: point estimate = 0.67 and Margin of error = 0.03 .

Step-by-step explanation:

For confidence interval,

Lower limit = point estimate - margin of error

Upper limit = point estimate + margin of error

Given confidence interval: (0.64, 0.70)

i.e. Lower limit = 0.64

Upper limit = 0.70

i.e. point estimate - margin of error= 0.64 (i)

point estimate + margin of error= 0.70 (ii)

Adding (i) and (ii) , we get

2( point estimate) = 1.34

⇒ point estimate = 0.67

Eliminate (i) from (ii) , we get

2( Margin of error ) = 0.06

⇒ Margin of error = 0.03

Hence, point estimate = 0.67 and Margin of error = 0.03 .
