Given that the mean distribution is 217, and the median is 291. This follows that given 217<291, it implies that most of the values lie to the left of the center of the distribution, hence the distribution will be positively skewed.
Hence,
the answer is:
<span>b.) it is positively skewed </span>
The national interest rate on houses for 25 years is 4.3%. The banker wishes to test that the local interest rates are lower than the national rate. So he should use the initial data of 4.3% interest as his base data. Then he should investigate the rates of houses in the local vicinities and compare it to his base data.
Answer:
P(blue) = 3/7
So '7' belongs in the box
Step-by-step explanation:
There are 14 total marbles, 6 of which are blue. The probability of pulling a blue marble out of the bag is
P(blue) = 6/14, which reduces to 3/7
The sum of them is 16,910 would be your answer
Answer:
<em>y=2 cos (π/4x-π/4)</em>
Step-by-step explanation:
<em>Given</em>
<em>A cosine function has an amplitude of 2, a midline of 5 and a period of 8.</em>
<em>To find: </em>
<em>A cosine function.</em>
<em>Explanation:</em>
<em>Let the function be,</em>
<em></em>
<em>Since amplitude is 2.</em>
<em>Then,</em>
<em></em>
<em>Also, since the period is 8.</em>
<em>Then,</em>
<em></em>
<em>And, since midline is 5.</em>
<em>Hence, the cosine function is,</em>
<em>y=2 cos (</em><em>x-</em>
