If Jeremy drinks 1 1/2 quarts of coffee every 3 days, how many liters of coffee would Jeremy drink in 3 weeks? (1 quart = 0.946

Nostrana [21]

Answer:

9.93 liter approximately 10 liter

Step-by-step explanation:

3 days = 3/2 quart

3 week = 3/2/3 × 21 quarts

= 1/2×21

=21/2 quarts

now

1 quart = 0.946 liter

21/2 quart = 0.946×21/2 liter

21/2 quart = 9.93 liter

Answer:

$\pmb{3x^4-3x^3-3x^2+2x+2 }$

<h3>Step to step explanation:</h3>

we have to subtract 5×⁴-4×³+3×²-2×from 8×⁴-7×³+2

$8x^4-7x^3+2-(5x^4-4x^3+3x^2-2x)\\\\8x^4-7x^3+2-5x^4+4x^3-3x^2+2x\\\\3x^4-3x^3-3x^2+2x+2$

How to write x is less than 5 and x is greater than 2

lesya [120]

Answer:

2 < x < 5

Step-by-step explanation:

<u>< This symbol means 'less than'</u>. The number you put on its left side is less than the number on its right side.

<u>> This symbol means 'greater than'</u>. The number put on its left is greater than its number on the right.

Think of them like a mouth. Remember the 'open side' wants to eat more.

Translate words to symbols:

'x is less than 5'

x < 5

'x is greater than 2'

x > 2

Put them together. The < and > symbols change directions, but x on the closed side of 5. Keep x on the open side of 2.

2 < x < 5

Don't confuse < and > with ≤ and ≥.

≤ and ≥ mean 'less than OR equal to' and greater than OR equation to'.

A lumber company is making doors that are 2058.0 millimeters tall. If the doors are too long they must be trimmed, and if the do

wariber [46]

Answer:

There is not enough evidence to support the claim that the doors are either too long or too short.

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 2058.0 millimeters

Sample mean, $\bar{x}$ = 2047.0 millimeters

Sample size, n = 17

Alpha, α = 0.10

Sample standard deviation, s = 27

First, we design the null and the alternate hypothesis

$H_{0}: \mu = 2058.0\text{ millimeter}\\H_A: \mu \neq 2058.0\text{ millimeter}$

We use Two-tailed t test to perform this hypothesis.

Formula:

$t_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{s}{\sqrt{n}} }$

Putting all the values, we have

$t_{stat} = \displaystyle\frac{ 2047.0 - 2058.0}{\frac{27}{\sqrt{17}} } = -1.6798$

Now, $t_{critical} \text{ at 0.10 level of significance, 16 degree of freedom } = \pm 1.7396$

Since, the calculated t statistic lies in the acceptance region, we fail to reject the null hypothesis and accept the null hypothesis.

Thus, there is not enough evidence to support the claim that the doors are either too long or too short.
