Answer:
I do not agree with Scott.
Step-by-step explanation:
22% *of* 160 --- meaning 22% times 160 --- is 35.2 so it's in fact approximately 35.
Answer:
Step-by-step explanation:
-x -6 ≤ 2 -(3x -4)
-x -6 ≤ 2 -3x + 4
-x ≤ -3x +12
2x ≤ 12
x ≤ 6
You would graph this on a number line with a solid dot on 6. Shade to the left.
An integer is close to zero if it is "small".
By small, we mean that it is small in absolute value. In fact, for any given distance
, there are two integers that are
units away from zero:
and
.
So, for example, -6 is close to zero than 8, because -6 is six units away from zero, while 8 is eight units away from zero.
So, the answer is B, -8, because it is 8 units away from zero. The other options A, C and D are, respectively, 12, 10 and 14 units away from zero.
Answer:
And we can find this probability with the normal standard distirbution or excel and we got:
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the lenghts of a population, and for this case we know the distribution for X is given by:
Where
and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability with the normal standard distirbution or excel and we got:
Answer:
45
Step-by-step explanation:
73+62=135
180-135=45
180 is the whole area of the triangle
