Answer:
The result in standard form is: 
Step-by-step explanation:
Dividing the values:
To find the real part, we divide 2.645 by 1.15. So
2.645/1.15 = 2.3
Finding the power:
Its a division, so we keep the base, and subtract the exponents. So
Result in standard form:
The result in standard form is:
The sample space of the experiment (i.e. the total number of ways he can pick 7 random pages out of a total of 6 + 4 = 10 pages) is given by:
If he picks at least 5 pages of maths homework, this means that he either picked 5 pages or 6 pages of maths homework.
The number of ways he can pick 5 or 6 maths homework is given by:
Therefore, the probability that he recovers at least 5 pages of his math homework is given by:
Answer:
Step-by-step explanation:
First of all, you can divide this shape to two different "easy" shapes.
One is rectangular, the other is triangle.
Area of the rectangular is: a*b
Area = a * b = 13 * 7 = 91
Area of the triangle is: 1/2*a *h
h of the triangle is 4 (as shown on the picture), so you've got:
Area = 1/2*4*13 = 26
Now you have to add this two areas to make one whole shape:
Area of the shape is: area of rectangular + area of triangle
Area of the shape is: 91 + 26 = 117
