2)5.1
3)2.8
4)2.4
5)I don't know what the last one is asking for, are there answer choices
Step-by-step explanation:
1)Max-min=58.3-52.2=6.1
2)Max-min=55-48.9=5.1
3)Upper quartile- lower quartile= 57.3-54.5=2.8
4)Upper quartile- lower quartile= 53.3-50.9=2.4
5) I don't know what this one is asking
Answer:
£6
Step-by-step explanation:
Let
Plain scones = x
Cheese scones = 3x
Fruits scones = 4(3x)
= 12x
Total price of scones = £96
She sells each scone for the same price.
Total price of scones = Plain scones + Cheese scones + Fruits scones
96 = x + 3x + 12x
96 = 16x
Divide both sides by 16
x = 96/16
= 6
Plain scones = x = £6
Cheese scones = 3x
= 3(6)
= £18
Fruits scones = 4(3x)
= 12x
= 12(6)
= £72
How much does she make from the sale of the plain scones?
She made £6 from the plain scones
Answer:
0.6443 = 64.43% of the business travelers will have to stoop
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean 
and standard deviation 
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
Each feet is 12 inches
So
5'9'' = 5*12 + 9 = 69
5'10'' = 5*12 + 10 = 70
What percentage of the business travelers will have to stoop?
This is 1 subtracted by the pvalue of Z when X = 69. So
has a pvalue of 0.3557.
1 - 0.3557 = 0.6443
0.6443 = 64.43% of the business travelers will have to stoop
Answer:
The engineer must verify and verify through a statistical inference that estimates and possible parameters may emerge, as well as determine what hypothesis tests should be performed to draw the most accurate conclusion.
Step-by-step explanation:
The engineer must assume that there may be more than one reasonable estimator for a different event or experiment; Something that could help you would be to perform an estimation of parameters, in that estimation it is required to know the properties of the estimators; that is to say that the closer the value of an estimator is to the real value of the parameter, it could be said that it is the most efficient or exact extimator.
Answer:
( 1, 0)
Step-by-step explanation:
you know that the slope of the MN line is 1/4 and a slope perpendicular to that is -4/1 ( negative and reciprocal ). then you can either draw a line from point p with the slope -4/1 and fine the point ( 1, 0 ) or you can do it the harder way which is plug the numbers into y=mx+b with 0 being b because you know the x-axis answer will have a y value of 0. (-4=-4x+0) and x is 1.
