Answer: 101.46 ounces in 3 liters

Step-by-step explanation:

To do this problem in the easiest way, you take your half liter and double your answer to make it one liter.

16.91 x 2= 33.82 ( 1 liter)

Now since you have one liter and you need 3 liters, all you do is triple your last answer to get 3 liters.

33.82 x 3= 101.46 ( 3 liters)

In a random sample of 16 residents of the state of Washington, the mean waste recycled per person per day was 2.8 pounds with a

Answer: The required confidence interval would be (2.72,2.89)

Step-by-step explanation:

Since we have given that

Mean = 2.8 pounds

Standard deviation = 0.24 pounds

n = sample size = 16

We need to find the 80% confidence interval for the mean waste.

z=1.341

So, the confidence interval will be

$\bar{x}\pm z\dfrac{\sigma}{\sqrt{n}}\\\\=(2.8\pm 1.341\times \dfrac{0.24}{\sqrt{16}})\\\\=(2.8\pm 1.314\times 0.06)\\\\=(2.8-0.07884,2.8+0.07884)\\\\=(2.72116,2.87884)$

Hence, the required confidence interval would be (2.72,2.89)

A: 28, 23,30, 25, 27

Serggg [28]

Answer:

Step-by-step explanation:

mean of A=28+23+30+25+27/5 = 26.6

average of B=22+19+15+17+20/5 = 18.6

now,

difference= 26.6-18.6

remember
a³-b³=(a-b)(a²+ab+b²)

so
$(x^2)^3-(3)^3=(x^2-3)(x^2+3x+9)$

Given that sine of theta = 21/29, what is the value of cosine of theta, for 0° < theta < 90°?

fenix001 [56]

If the value of θ is 46.4°. Then the value of the cosine of θ will be 20/29.

<h3>What is trigonometry?</h3>

The connection between the lengths and angles of a triangular shape is the subject of trigonometry.

The value of sine of θ is 21/29.

Then the value of θ will be

sin θ = 21/29

θ = sin⁻¹(21 / 29)

θ = 46.4°

Then the value of the cosine of θ will be

cos θ = cos 46.4°

cos θ = 20/29
