Answer:

Step-by-step explanation:

The perimeter of the given triangle:

P = (2x + 1) + (x + 2) + (3x - 9) and P = 36 cm.

Therefore we have the equation:

2x + 1 + x + 2 + 3x - 9 = 36 combine like terms

(2x + x + 3x) + (1 + 2 - 9) = 36

6x - 6 = 36 add 6 to both sides

6x = 42 divide both sides by 6

x = 7

lana [24]

Answer:

Option d: n = 36, p = 0.97, x = 36.

Step-by-step explanation:

We are given that a soup company puts 12 ounces of soup in each can. The company has determined that 97% of can have the correct amount.

We have to describe a binomial experiment that would determine the probability that a case of 36 cans has all cans that are properly filled.

Let X = Number of cans that are properly filled

The above situation can be represented through binomial distribution;

$P(X = x) = \binom{n}{x} \times p^{x} \times (1-p)^{n-x} ; x = 0,1,2,........$

where, n = number of trials (samples) taken = 36 cans

x = number of success = all cans are properly filled = 36

p = probabilitiy of success which in our question is probability that

can have the correct amount, i.e. p = 97%

So, X ~ Binom (n = 36, p = 0.97)

Hence, from the options given the correct option which describes a binomial experiment that would determine the probability that a case of 36 cans has all cans that are properly filled is n = 36, p = 0.97, x = 36.

A student noticed that the average diameter of the glass beads used for the mass measurements was significantly smaller than tho

Levart [38]

Answer:

The error mentioned is a systematic error.

Step-by-step explanation:

The glass beads used for mass measurements was noticed to be significantly smaller than those used for volume measurements.

The formula for density is = $\frac{mass}{volume}$ .

So if we try to experimentally determine the value of density of glass then the beads for measuring the mass are much smaller than the beads for measuring volume.Thus in this case we can see that the density measured will actually be less than the actual density of glass.

However since this error can be seen and quantified and corrected it is not a random error, but it is a systematic error.
