Answer:

its hard to explain as a simple answer but i can explain w an example

Step-by-step explanation:

lets say the equation is 2 (3×5), rather than using pemdas and doing 3×5 fist, you take the 2 amd multiply it by the numbers in the paranthesis, so, do that snd u get 2×3 which equals 6 and then u do 2×5 which equals 10 so the equation in the end should be 6+10 which equals 16, and obviously if u use pemdas u would gey a different answer (the answer if u use pemdas is 30)

Without graphing or solving either system of equations explain how you know what the solution to the system is.

Sonbull [250]

x = 5

y = -1

Step-by-step explanation:

from second equation,

y = -2 + 1
y = -1

by putting the value of y in first equation

y = -x + 4
-1 = -x + 4
-x = -1 -4
-x = -5
x = 5

x = 5 and y = -1

Approximately 40% of the calls to an airline reservation phone line result in a reservation being made. (round to three decimal

IRISSAK [1]

Answer:

The probability that none of the 10 calls result in a reservation is 0.60%. In turn, the probability that at least one call results in a reservation being made is 99.40%.

Step-by-step explanation:

Since approximately 40% of the calls to an airline reservation phone line result in a reservation being made, supposing an operator handles 10 calls, to determine what is the probability that none of the 10 calls result in a reservation, and what is the probability that at least one call results in a reservation being made, the following calculations must be performed:

0.6 ^ 10 = X

0.006 = X

0.006 x 100 = 0.60%

Therefore, the probability that none of the 10 calls result in a reservation is 0.60%.

100 - 0.60 = 99.40

In turn, the probability that at least one call results in a reservation being made is 99.40%.

In ΔLMN, l = 870 cm, ∠N=117° and ∠L=17°. Find the length of n, to the nearest 10th of a centimeter.

MAXImum [283]

We have been given that in ΔLMN, l = 870 cm, ∠N=117° and ∠L=17°. We are asked to find the length of n to the nearest 10th of a centimeter.

We will use law of sines to find the length of n.

Law of sine states the relation between the angles of a triangle and their corresponding side.

$\frac{a}{\text{sin(A)}}=\frac{b}{\text{sin(B)}}=\frac{c}{\text{sin(C)}}$ , where a, b and c are corresponding sides to angles A, B and C respectively.
