Answer:

Here the type of equations are inconsistent.

Step-by-step explanation:

Given:

line l is parallel to line m ..............{Given}

As equations are not given we will define the terms

Consistent : consistent type equations are those equations which have solutions. Two intersecting lines are consistent and have one solution.

Equivalent : When the same line is written in two different forms so that there are infinite solutions. Coincident lines are the same line written in two different forms and have in finite solutions.

Inconsistent :Inconsistent type equations are those equations which have no solution.

parallel lines have no solutions

Is 46.03 greater than or less than 46.030

Tcecarenko [31]

Answer:

It should be they are equal to each other.

Step-by-step explanation:

A trucking firm suspects that the mean lifetime of a certain tire it uses is more than 30,000 miles. To check the claim, the fir

grandymaker [24]

Answer:

We conclude that the lifetime of tires is less than 30,000 miles.

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 30,000 miles

Sample mean, $\bar{x}$ = 29,400 miles

Sample size, n = 54

Alpha, α = 0.05

Population standard deviation, σ =1200 miles

First, we design the null and the alternate hypothesis

$H_{0}: \mu = 30000\text{ miles}\\H_A: \mu < 30000\text{ miles}$

We use One-tailed z test to perform this hypothesis.

Formula:

$z_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }$

Putting all the values, we have

$z_{stat} = \displaystyle\frac{29400 - 30000}{\frac{1200}{\sqrt{54}} } = -3.6742$

Now, $z_{critical} \text{ at 0.05 level of significance } = -1.64$

Since,

$z_{stat} < z_{critical}$

We reject the null hypothesis and accept the alternate hypothesis.

Thus, we conclude that the lifetime of tires is less than 30,000 miles.

ExtremeBDS [4]

Answer:

32 ft²

Step-by-step explanation:

Scale factor

2 cm to 1 ft

Size of each garden bed on the drawing

8 cm by 16 cm

Actual size

8cm = 4*2 cm ⇔ 4 ft
16 cm = 8*2m ⇔ 8 ft

Area of one garden bed

4 ft * 8 ft = 32 ft²
