You would multiply 18 and -13 then plus by 14 and see if you get -220.
Y=root of x+ 5,3rd option,apply -4 there then root of 1 is 1.hope helped you.
Answer:
maybe it's 10.because c is 10,b is 10,and so as s.
hence s is 10 also.
The answer is A. Here's how you get it. Law of cosines here looks like this:
17^2 = 22^2 + 30^3 - [2(22)(30)cosA]; which simplifies to 289=484+900-1320(cosA). Doing that math gives you 289 = 1384 - 1320(cosA), and -1095 = -1320(cosA). Divide both sides by -1320 to get
.829545 = cos A. Now use the inverse cosine on your calculator to get the missing angle measure.
Answer:
Kindly check attached picture
Step-by-step explanation:
Given the data:
65 72 68 64 60 55 73 71 52 63 61 74
69 67 74 50 4 75 67 62 66 80 64 65
The box and whisker plot generated from the data above can be found in the picture below : The asterisked point on the plot is the value of the Outlier.
Using calculator :
Q1 = 61.25 Q2 = 65.5 ; Q3 = 71.75
IQR = Q3 - Q1 = 71.75 - 61.25 = 10.5
Lower limit: Q1 − 1.5 * (IQR)
61.25 - 1.5(10.5)
61.25 - 15.75 = 45.5 (all values below 45.5)
Upper limit: Q3 + 1.5 * (IQR)
71.75 + 1.5(10.5)
71.75 + 15.75 = 87.5 (all values above 87.5)
Hence, the box and whisker plot summary :
Sample size: 24
Median: 65.5
Minimum: 4
Maximum: 80
First quartile: 61.25
Third quartile: 71.75
Interquartile Range: 10.5
Outlier: 4
