Answer:
15 x 1 + 5 x 3 = 30
Step-by-step explanation:
If you turn the x into a one then it multiplies 15 by one and then it remains at 15, then you multiply 5 and 3 so that's 15 and then 15 + 15 is 30.
If one third of the loaf was left and there is six pieces left you multiply 3×6=18
There was originally 18 slices of bread
Answer:
Phythagorean Theorem - a^2 + b^2 = c^2
Step-by-step explanation:
It represents the Pythagorean Theorem because in the model there is a right triangle and you can use the phythagoren theorem with any right triangle that has at least two known sides.
Since you know all the sides in this diagram, this would be true:
6^2 + 8^2 = 10^2
Answer:
15 ft
Step-by-step explanation: To solve this, you have to use the Pythagorean Theorem. The 25 ft is the hypotenuse, the longest side of the triangle. the building's height, 20 ft is one of the legs. The missing measurement is one of the other legs.
Pythagorean Theorem: A^2 + B^2 = C^2
A and B are legs and C is the hypotenuse.
Substitute the values:
20^2 + B^2 = 25^2
400+ B^2 = 625
625 - 400 = 225
225 = 15^2
Answer:
Step-by-step explanation:
The confidence interval for population proportion is given by :-
Given : Significance level :
Critical value :
Then a 99% confidence interval is constructed to estimate the difference in population proportions which possess the given characteristic will be :-
Hence, the resulting confidence interval is .
