Answer:
x = 16
Step-by-step explanation:
x - 12 = 4
+ 12 = +12
x = 16
Answer:
16
Step-by-step explanation:
Step-by-step explanation:
Letthe two numbers be x and y
By the question
x +y =87.....equation (I)
x -y =65......equation (II)
Now adding both equations we get
2x =152
x =152/2
Therefore x =76
Putting x =76in equation i
76+y =87
y =87-76
Therefore y =11
The two numbers are 76and 11.
Hope it helps :)
Answer:
11, 76
Step-by-step explanation:
Let the two numbers be x and y.
According to the given conditions:
x + y = 87.....(1)
x - y = 65....(2)
Adding equations (1) & (2)
x + y = 87
x - y = 65
__________
2x = 152
x = 152/2
x = 76
Plug x = 76 in equation (1)
76 + y = 87
y = 87 - 76
y = 11
Thus the two numbers are 11 and 76.
Answer:
(a) The first quartile is 382.27 and it means that at least el 25% of the scores are less than 382.27 points.
The second quartile is 462 and it means that at least el 50% of the scores are less than 462 points.
The third quartile is 541.73 and it means that at least el 75% of the scores are less than 541.73 points.
(b) The 99th percentile is 739.27 and it means that at least el 99% of the scores are less than 739.27 points.
Step-by-step explanation:
The first, second the third quartile are the values that let a probability of 0.25, 0.5 and 0.75 on the left tail respectively.
So, to find the first quartile, we need to find the z-score for which:
P(Z<z) = 0.25
using the normal table, z is equal to: -0.67
So, the value x equal to the first quartile is:
Then, the first quartile is 382.27 and it means that at least el 25% of the scores are less than 382.27 points.
At the same way, the z-score for the second quartile is 0, so:
So, the second quartile is 462 and it means that at least el 50% of the scores are less than 462 points.
Finally, the z-score for the third quartile is 0.67, so:
So, the third quartile is 541.73 and it means that at least el 75% of the scores are less than 541.73 points.
Additionally, the z-score for the 99th percentile is the z-score for which:
P(Z<z) = 0.99
z = 2.33
So, the 99th percentile is calculated as:
So, the 99th percentile is 739.27 and it means that at least el 99% of the scores are less than 739.27 points.
Answer:
69
Step-by-step explanation:
Since m is parallel to n, there are special rules that apply to these angles. One such rule is corresponding angles, which are angles in matching corners. In this case, both of the angles are in the bottom right, which makes them corresponding. Corresponding angles are always congruent, therefore x=69.
Answer:
69 degrees
Step-by-step explanation:
b. –9 + 9i
c. –5 + 9i
d. –5 – 3i
Answer:
d
Step-by-step explanation:
(-7 + 3i) + (2-6i)
=-7 + 3i + 2 -6i
=(-7+2) + (3i -6i)
=-5 -3i
Answer:
(-7+3I)+(2-6I)
= -7+3i+2-6i
= -5-3I
so answer is d ie -5-3i
Answer:
maximum profit is$2400 when 4 necklace and 3 brackets are made.
Step-by-step explanation:
Total gold = 18 ounces
Total platinum = 20 ounces.
let X₁ represents the necklace and X₂ represents the bracelets.
maximize:
with constraints:
for gold:
---(1)
for platinum:
---(2)
The demand for bracelets is no more than four i.e.
---(3)
To maximize profit, formulate a linear programming model with constraints for the number of necklaces and bracelets to produce. Solve the model using graphical analysis to find the optimal solution.
To formulate a linear programming model for this problem, let x be the number of necklaces to produce and y be the number of bracelets to produce. The objective is to maximize profit, which can be expressed as: Profit = 300x + 400y. The constraints are: 3x + 2y ≤ 18 (gold constraint), 2x + 4y ≤ 20 (platinum constraint), 0 ≤ x ≤ infinity (non-negativity constraint), and y ≤ 4 (demand constraint).
To solve this model using graphical analysis, graph the feasible region determined by the constraints. The feasible region is the region in which all constraints are satisfied. The optimal solution will be at one of the corner points of the feasible region. Calculate the objective function at each corner point and select the one that maximizes profit.
