1 answer:
gulaghasi [49]2 years ago

Answer:

65 degrees

Step-by-step explanation:

<u>Step 1:  Find what the measure of JLK is</u>

JLM + JLK = 180

140 + JLK - 140 = 180 - 140

JLK = 40

<u>Step 2:  Find what the measure of KJL is</u>

KJL + JLK + JKL = 180

KJL + 40 + 75 = 180

KJL + 115 - 115 = 180 - 115

KJL = 65

Answer:  65 degrees

The probability of a getting a new sales contract with any given client is 0.29. A sales representative works with 18 clients th
Radda [10]

Answer:

The expected number of contracts the sales representative will get this week is 5.22

Step-by-step explanation:

For each client, there are only two possible outcomes. Either there is a sales contract, or there is not. The probability of having a sale contract with each client is independent of other clients. So we use the binomial probability distribution to solve this problem.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The expected value of the binomial distribution is:

E(X) = np

In this problem, we have that:

n = 18, p = 0.29

What is the expected number of contracts the sales representative will get this week?

E(X) = np = 18*0.29 = 5.22

The expected number of contracts the sales representative will get this week is 5.22

1 Si el radicando tiene más de dos cifras separamos las cifras en grupos de dos, empezando por la derec2 Calculamos la raíz cuadrada entera o exacta, del primer grupo de cifras por la izquierda, ha.3 El cuadrado de la raíz obtenida 2 (es decir 4) se resta al primer grupo de cifras que aparecen en el radicando Bajamos el siguiente grupo de cifras del radicando, separando del número formado (492) la primera cifra a la derecha (2) y dividiendo lo que resta entre el doble de la raíz 2, es decir 2(2)=4.  5En otra fila debajo de la raíz colocamos el doble de la misma (4). A continuación, se coloca el cociente que se obtenga (9) . Y luego el número obtenido (49) se multiplica por dicho cociente (9). Después, se resta (441) a la cantidad operable (492) del radicando.  El cociente obtenido (9) es la segunda cifra de la raíz, quedando (29) Bajamos el siguiente par de cifras y repetimos los pasos anteriores.

Answer:

10

Step-by-step explanation:

10 workers working 2 hours a day is 2*10=20 work hours per day

2 workers working 5 hours a day is 2 *5=10 work hours per day

Per day 1/2 as many work hours so will take 2 times as long.

5*2 = 10 days
