Answer:
-5F + 34* = 29*F
Step-by-step explanation:
Have a nice day! :-)
Kindly note that the question says 4; maybe the final question was intended to be the probability that he gets exactly 2 of the 4 correct. However. If it is the other way round. This a e procedure used in the solution should also be followed.
Answer:
0.21
Step-by-step explanation:
Number of options = 4
One correct answer per option ; hence, the probability of success, p = 1/4 = 0.25
Using the binomial probability relation :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
x = 2 ; n = 4
p = 0.25 ; 1 - p = 0.75
P(x = 2) = 4C2 * 0.25^2 * 0.75^2
P(x = 2) = 6 * 0.0625 * 0.5625
P(x = 2) = 0.2109375
P(x = 2) = 0.21 (2 decimal places)
Note : if the question was 3, then put, n = 3 instead of 4
Step-by-step explanation:
With the given points, we can first find the gradient of the line:
gradient = (2+1)/(-4-8)
= -1/4
We also know that the formula of a straight line is
Y = mX+C, where m is gradient and C is y intercept.
Hence by substituting the coordinates (-4, 2) and the gradient -1/4, we get:
2 = (-1/4)(-4) + C
<u>C = 1</u><u>.</u> Hence, Answer is C.
(Actually, you can just draw a straight line connecting the 2 coordinates and find out the y intercept)
Answer:
y+5/3x=34/3
Step-by-step explanation:
y=mx+b
3=5m+b
-2=8m+b (system of equations, subtract them)
5=-3m
-5/3=m
3=5m+b
3=5(-5/3)+b
3=-25/3+b
9/3+25/3=b
34/3=b
y=-5/3x+34/3
y+5/3x=34/3
.9 1/2 cups is equal to 19/4. divide 19 by 3 (the 3 from 3/4) and you get 6 1/4. Skylar can make 6 batches with this one bag of sugar.
