Answer:
value of 4 tan 45° +(2 sin 45°) (6 cos 45°) is 10.
Step-by-step explanation:
To solve this question we need to know value of
tan 45° = 1
sin 45° =
cos 45° =
we will be using above value sin the given expression as shown
Thus, value of 4 tan 45° +(2 sin 45°) (6 cos 45°) is 10.
Answer:
$37.50
Step-by-step explanation:
\[[6\frac{1}{2} -5=1\frac{1}{2} =\frac{3}{2}\]
more interest earned=2500×1×3/2×1/100=37.50$
I think it’s 15..
cause you replace the x with -5 and solve the problem
Answer:
95% of the text messages have length between 23 units and 47 units.
Step-by-step explanation:
We are given the following in the question:
The lengths of text messages are normally distributed.
95% confidence interval:
(23,47)
Thus, we could interpret the confidence interval as:
About 95% of the text messages have length between 23 units and 47 units.
By Empirical rule for a normally distributed data, about 95% of data lies within 2 standard deviations of mean , thus we can write:
Thus, the mean length of text messages is 23 units and standard deviation is 6 units.
