Answer:
A)(7,-9)
Step-by-step explanation:
we know x=7
so put it in the equation
y= -2(7)+5
y=-9
we always put the x coordinate first and then the y coordinate so the answer is (7,-9)
Let the faculties be X and the number of students be Y.
X/Y = 17/3
3X= 17Y
X=17Y/3
Let that be equation 1
We also know that X+Y = 740. Let it be equation 2
Substitute equation 1 in equation 2
(17Y/3)+Y= 740
20Y/3 = 740
Y=111
Since the total is 740, then X equal 740-111 =629.
The number of faculties is 111 and the number of students is 629.
There are 6 sides on a dice. This means each number has a 1/6 chance of appearing. (1 number out of 6 sides). This includes 6, so the answer to a is 1/6. If you roll or do not roll a six, this means every side of the dice counts. The answer to be, by extension, is 6/6. Finally, c is b (the probability of anything) minus a (the probability of a six), representing every situation that is not a 6, so 5/6.
the correct answers would be yes,no,yes,yes, and no. the yes answers all simplify to the expression 42x+14
Answer:
The correct option is;
A. 0.17
Step-by-step explanation:
The given information are;
The mean duration it takes a cashier to process an order, μ = 276 seconds
The standard deviation from the mean, σ = 38 seconds
The z-score of the order processing time of x = 240 seconds is given as follows;
Therefore;
The probability
P(z = -0.9474) = 0.17361
Therefore, the proportion of orders which are processed in less than 240 is approximately 0.17361 or 0.17 to two places of decimal.
