Kate is 3 years old
Explanation:
Kate is x for example, then her father would be
x+32
In five years he would be x+32+5, x+37, but he would also be 5 times older.
Kate will also be x+5.
SO, we know that
x+37=5 · (x+5)
When we simplify, we get
x+37 = 5x+25
Simplify further, you get
12=4x, so
3=x
Kate is 3 years old currently
6y-4=4y+2
2y=6, so y=3.
Plugging it in, you get that AC equals 4*3+2=14.
This is an isosceles triangle.
Answer:
Leagnth = 11
Width = 5
Step-by-step explanation:
Simple. 5 which could be the width multiplied three times is 15. Subract 4 from it. You have 11. 11 x 5 = 55, your area.
Radius equals: 4.51

Based on the information given, it should be noted that the mean and standard deviation of Y will be 0.4899 and 0.699 respectively.
<h3>Calculating the mean.</h3>
Based on the information given, it should be noted that the probability distribution for y will be:
Y 0 1. 2
Probability 0.63. 0.25. 0.12
The mean of Y will be:
= (0 × 0.63) + (1 × 0.25) + (2 × 0.12)
= 0 + 0.25 + 0.25
= 0.49
The variance will be 0.4899. Therefore, the standard deviation will be:
= ✓0.4899
= 0.699
