Take a square root if both sides and you will get
a+6=7 and a+6=-7

For a+6=7
Subtract 6 from both sides
a=1

For a+6=-7
Again subtract 6 from both sides
a=-13

Therefore, the last answer is correct

A baseball club pays a vendor $135 per game for selling bags of peanuts for $4.25 each. (a) Write a linear function that describ
qaws [65]

A linear function is a numerical relationship that forms a straight line in the Cartesian plane and represents the number of units that change a dependent variable, increase or decrease, compared to an independent one, in this case the profit P of the baseball club will be given by the number b of peanut bags sold multiplied by the sales value ($4,25), this less the payment of the seller's work day ($135), that is:

P = $4.25 b-$135

Answer

The linear function that describes the profit of the baseball club is

P = 4.25 b-135

Given klmn is a trapezoid, kl = mn, m<1 = m<2, lm/kn = 8/9, pklmn = 132. Find: the length of the legs
Ilia_Sergeevich [38]

Answer:

The length of legs lm, mn, and lk is 32 while that of kn is 36.

Step-by-step explanation:

The diagram is attached in the answer.

As both the angles are equal thus the two forms isosceles triangles. This is true because the converse of base angle theorem is applicable here. The theorem clearly states that when a trapezoid is divided by the diagonal, it forms two set of angles where m<1=m<2 and m<lmk=m<nmk

This leads the two set of legs such as

\dfrac{lm}{kn}=\dfrac{8}{9}

Or this could be written as

lm=8x\\kn=9x

Now the remaining two sides are given as

lk=lm as this form an isosceles triangle so

lk=8x

Similarly

mn=lm\\

Or

mn=8x

Now the perimeter is given as

\text{perimeter}=lm+mn+kn+lk\\

Here perimeter is given as 132 so this gives:

\text{perimeter}=lm+mn+kn+lk\\132=8x+8x+8x+9x\\132=33x\\x=\dfrac{132}{33}\\x=4

So the four legs are of length as given below:

lm=8x=8\times 4=32\\mn=8x=8\times 4=32\\lk=8x=8\times 4=32\\kn=9x=9\times4=36

So the length of legs lm, mn, and lk is 32 while that of kn is 36.

Yea that can be a good equation. I had this question last year and my teacher said it was ok.

But it can be wrong, I don't really know. Cuz we don't go to the same school.

The probability distribution of customers that walk into a coffee shop on any given day of the week is described by a Normal dis
Leni [432]

Answer:

15.87% probability that no more than 80 customers walk into the coffee shop next Monday

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

\mu = 100, \sigma = 20

What is the probability that no more than 80 customers walk into the coffee shop next Monday?

This is the pvalue of Z when X = 80. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{80 - 100}{20}

Z = -1

Z = -1 has a pvalue of 0.1587.

So there is a 15.87% probability that no more than 80 customers walk into the coffee shop next Monday
