Answer: I make 15 dollars every week at my job
Step-by-step explanation: your x is likely representing a time like weeks and your y is most likely going to be the amount of something like money. so if x increases by one every time and y increases by 15 every time your scenario could be i make 15 dollars every week at my job.
Answer:
a)%85,5
b)%92,2
Step-by-step explanation:
a) To determine the probability of getting a hand with at least one face, we need to calculate the probability of the hand without any face firstly.
![(36/52)*(35/51)*(34/50)*(33/49)*(32/48)=0,145](https://tex.z-dn.net/?f=%2836%2F52%29%2A%2835%2F51%29%2A%2834%2F50%29%2A%2833%2F49%29%2A%2832%2F48%29%3D0%2C145)
Then, we need to deduct this value from the probability 1
![1-0,145=0,855](https://tex.z-dn.net/?f=1-0%2C145%3D0%2C855)
The probability of the hand with at least one face is %85,5.
b)To determine the probability of a hand with at least one ace and face we will track the same road again.
![(32/52)*(31/51)*(30/50)*(29/49)*(28/48)=0,0775](https://tex.z-dn.net/?f=%2832%2F52%29%2A%2831%2F51%29%2A%2830%2F50%29%2A%2829%2F49%29%2A%2828%2F48%29%3D0%2C0775)
Then, we need to deduct this value from the probability 1
![1-0,0775=0,922](https://tex.z-dn.net/?f=1-0%2C0775%3D0%2C922)
The probability of the hand with at least one ace and one face is %92,2.
Answer:
- 0.8
Step-by-step explanation:
The first thing we want to do here is simplify the expression -
( 2x + 5 ) - 2x, Distribute the "
" to elements within the parenthesis
=
2x +
5 - 2x, Focus on simplifying the expression "
2x +
5 "
=
- 2x
=
- 2x, Combine fractions
=
+ 3
=
x + 3
So we have our simplified expression "
x + 3, " with
being the coefficient of x. Our requirements are that this fraction should be expressed as a decimal, so we can simply divide the numerator by the denominator to figure that out,
- 4 / 5 = - 0.8,
Solution = - 0.8
Answer:
-2.6
Step-by-step explanation:
10.9 + (-15.6) becomes 10.9 - 15.6 which equals -4.7. The last step is to add the 2.1 to the -4.7: -4.7 + 2.1 = -2.6
Therefore the answer is -2.6
Answer: 28.75° and 61.25°
Step-by-step explanation:
A complementary angle equals 90°.
Let the measure of the angle be a
Therefore, its complement will be:
= 90-a.
The complement of an angle is 25 less than 3 times the angles itself can be written as:
90-a = 3a - 25
90 + 25 = 3a + a
115 = 4a
a = 115/4
a= 28.75
Since the angle is 28.75°, the complement will be:
= 90° - 28.75°
= 61.25°
The angles are 28.75° and 61.25°
