Step-by-step explanation:

Function of the cylinder is to measure liquid volumes accurately. They are extensively used in chemistry and biology labs, where quantities of accurately measured liquids need to be used. They are purposely designed to be long, with a shorter diameter compared to beakers, to facilitate accurate measurements.

Ragan makes beaded jewelry. The graph below shows the number of beads on varying cord lengths.

MakcuM [25]

Answer:

Option C) 34 inches

Step-by-step explanation:

We are given the following in the question:

The graph shows the number of beads on varying cord lengths.

The y-axis represents the number of beads and x-axis represents the cord length in inches.

The graph represents the equation:

$y = 2.52x + 1.61$

where y is the number of beads and x is the cord length.

We have to find the cord length of a necklace consisting of 88 beads.

Thus, we are given y = 88.

Putting this value in the equation, we get,

$y = 2.52x + 1.61\\88 = 2.52x + 1.61\\2.52x = 88 - 1.61\\2.52x = 86.39\\\\x = \displaystyle\frac{86.39}{2.52} = 34.28 \approx 34$

Thus, the cord length of necklace with 88 beads is approximatwly 34 inches.

Calculate the value of 0. Write your equation.

Crazy boy [7]

Answer:

θ = 67.4°

Step-by-step explanation:

using the SOHCAHTOA method,

Here opposite is 12 cm, hypotenuse is 13 cm, adjacent is 5 cm.

Using the formula:

$sin(\beta ) = \frac{oppsoite }{hypotenuse}$

$sin(\beta ) = \frac{12}{13}$

$\beta = sin^{-1}(\frac{12}{13} )$

β = 67.4°

If 90 percent of automobiles in Orange County have both headlights working, what is the probability that in a sample of eight au

Marta_Voda [28]

Answer:

$P(X \geq 7) = P(X=7) +P(X=8)$

And we can find the individual probabilities using the probability mass function

$P(X=7)=(8C7)(0.9)^7 (1-0.9)^{8-7}=0.3826$

$P(X=8)=(8C8)(0.9)^8 (1-0.9)^{8-8}=0.4305$

And replacing we got:

$P(X \geq 7) = P(X=7) +P(X=8)=0.3826 +0.4305=0.8131$

Step-by-step explanation:

Previous concepts

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

Solution to the problem

Let X the random variable of interest "number of automobiles with both headligths working", on this case we now that:

$X \sim Binom(n=8, p=0.9)$
