The spinner is divided into four equal sections: 2, 4, 7, 9. This represents 4 possibilities
If the spinner is spun twice, the sample space is:
For product less than 30, the number of outcomes is shown below:
The number of outcomes that have a product less than 30 = 10
The sample space that shows possibilities of an odd number combination:
The number of outcomes that contains at least one odd number = 12
The number of outcomes that have a product less than 30 and contain at least one odd number is shown below. These outcomes are outcomes circled in both cases shown above,
The outcomes circled represents the number of outcomes that has a product less than 30 and contains at least one odd number
Answer: 6 (option B)
Your answer will be 17/15
Firstly you should use Pythagorean’s theorem like this
H²=p²+b²
Where p is bc
And b is ac
Then keep the value and solve it and you will get h as 17
At last keep cosA = b/ h

If you didn’t understand please tell me
"The digit at tens place is four times the digit at units place."
How many possible numbers are there?
1 in the units place: 41
2 in the units place: 82
If you try 3 in the units place, 4 * 3 = 12, you'd get 123, and now it's a three-digit number, so the only possibilities are 41 and 82.
41 or 82
If you subtract 54 from 41, you get a negative number, so 41 cannot be the number.
82 - 54 = 28, which has the digits of 82 in reverse order.
Answer: 82
I hope this helps you
2x^2+5x+5=0
disctirminant =5^2-4.2.5
disctirminant = -15
x1= -5+i .square root of 15/2.2
x2= -5- i .square root of 15/2.2
if you're adding or subtracting quantities with uncertainties, you add the absolute uncertainties. If you're multiplying or dividing, you add the relative uncertainties. If you're multiplying by a constant factor, you multiply absolute uncertainties by the same factor, or do nothing to relative uncertainties
