Answer: The first equation can be used to find the answer.
The solution to y^2 is 80
Answer:
a) 0.076
b) 0.5
c) 0.084
d) 0.25
e) 0.00024
f) 0.156
Step-by-step explanation:
a) In an ordinary deck there are 4 aces. The probability of getting an ace is given by:
n: options for an ace = 4
N: total number of cards = 52
The probability is 7.6%
b) On the first 100 positive integers, there are 50 odd integer numbers. Then you have:
The probability of getting an odd number is 50%
c) From a total of 365 day in the year, May has 31 day. Then you have:
The probability is 8.4%
d) In this case you have two events. To get an odd number with the sum of the number of two dices you need and odd number in one dice and a pair number in the other dice.
The probability is the product of the occurrence of both events. The probability for an odd number is 1/2 and for a pair number is 1/2.
The probability is 25%
e) To obtain Head 6 times in a row, the probability is:
Probability of 0.024%
f) To get Head 4 times from 5 flights, you first calculate the probability for 1 head in five flips:
There are 5 forms of getting 4 Heads for 5 flips, then you have:
Te probability is 15.6%
Answer:
So the answer is 12 and 31.
Step-by-step explanation:
Let the smaller number be x and the larger number be y.
We can calculate this by using simultaneous equation, aka listing 2 equations out.
From given,
X + y = 43
Let this be equation no. 1
X + 19 = y
Let this number be equation 2.
We can do simultaneous equations either by substitute method or elimination. In this case I'm using substitute.
We can already obtain the value of y (in terms of x) in euqation no. 2, so all we gonna do is to put y into equation 1.
X + x + 19 = 43
Solve this by algebra.
2x = 43 - 19
X = 12
Now we know the exact value of x
Now substitute x = 12 into equation no. 2
12 + 19 = y
Y = 31
Answer:
The area of shaded region is 208 sq.feet
Step-by-step explanation:
Refer the attached figure
ABCD is rectangle
Opposite sides of rectangle are equal so
AB = CD = 16 feet
AD = BC= 17 feet
Area of rectangle =
Now In triangle PCD
CD = 16 feet
PC = BC-BP = 17-9 = 8 feet
Since all angles of rectangle is 90°
So,PCD is a right angles triangle
So, Area of triangle =
Area of shaded region = Area of rectangle - Area of triangle =
Hence The area of shaded region is 208 sq.feet
Mathematical equation -
20 + 0.50x = ?
X is the placeholder which in this case equals months
But in this case you want to look for form month three to month 18 (which is 15 months) so three months went by so the equation is
$61.50(being the three months already)
(20+(0.50*15))+61.50=?
