Answer:
y = 2x + b (the second answer choice)
Step-by-step explanation:
The slope-intercept form is y = mx + b (the m representing slope and the b representing y-intercept). Put the points in ratio form as a fraction and subtract the ratio with the smallest numbers from the ratio with the largest ratio (5/1 - 1/-1) to get 4/2. When simplified, it becomes 2/1, so the slope is 2. Using the slope found previously, subtract 1 from the x of (1, 5) and 2 from the y of (1, 5) to get the y-intercept. The resulting point is (0, 3), so the y-intercept is 3. Replace the m with the found slope (2) and b with the found y-intercept (3) to end up with y = 2x + 3.
Answer:
This is a reasonable decision because the sample size has no effect on the 90% confidence interval
Step-by-step explanation:
90% confidence interval
larger sample size = 20
condition : sample mean ( x-bar ) is the same for both samples
<em>This is a reasonable decision because the sample size has no effect on the 90% confidence interva</em>l
<u>from condition 1 :</u>
Amount of drink dispensed is normally distributed with known standard deviation , given a random sample of n drinks and the sample mean at a confidence interval of 90%
<u>for condition 2 :</u>
sample size = 20
mean = 2.25 ( assumed value )
std = 0.15 ( assumed value )
Z = 1.645 ( Z-value )
determine the 90% confidence interval
= mean ± z 
= 2.25 ± 1.645 
= 2.25 ± 0.0335 = ( 2.2835 , 2.2165 )
I have to assume that you want the answer in Spanish *but without using accents).
Usa las siguientes variables:
d = numero de habitaciones dobles
i = numero de habitaciones individuales
Por la primera premisa:
d + i = 180
Por la segunda premisa, los costos son tales que:
78d + 72i = 7839
Para resolver ese sistema podemos despejar una de las variables de la primera ecucacion y sustituir en la segunda:
i = 180 - d
78d + 72 (180 - d) = 7839
78d + 12960 - 72d = 7839
De aqui ya veo que va a dar un numero negativo para el numero de habitaciones dobles, asi que supongo que algun dato en el enunciado esta equivocado.
6d = 7839 - 12960 = -5121
=> d = -5121 / 6 = - 853.5
Al corregir los datos podras seguir el procedimiento que te he explicado para encontrar la solucion.
Answer: 216
Step-by-step explanation:
12/20 so 12 times 18 is 216
<h2>
Hello!</h2>
The answer is $101688
<h2>
Why?</h2>
Since there is not enough information about the rate, let's assume that it's a daily rate.
<h2>Calculations</h2>
Let's say:
P : Proceeds
o : original amount
d : number of days
r : percentual rate
So,
Let's make the percentual rate (6,5%) a real number by dividing into 100,
By substituting, we have
$101688
Have a nice day!
