1st step, divide both sides by 4
2nd step, move 2 to the right side and change the plus to a minus
3rd step, subtract the numbers
the answer is x=4 I did the work i dont know if it helped but I hope it did. also, sorry for my handwriting I was rushing
autotrophs or heterotrophs:
(a) a giant redwood tree,
(b) a spider,
(c) a rose bush,
<span>(d) a mushroom,
(e) a blue whale.
</span>autotrophs=a)and (c)
<span>heterotrophs=b)d)and e)</span><span>
Hope This helped!</span>
Answer:
Area of triangle RST = 95 in² (Approx)
Step-by-step explanation:
Given:
Side a = 22 in
Side b = 13 in
Perimeter = 50 in
Find:
Area of triangle
Computation:
Side c = Perimeter - Side a - Side b
Side c = 50 - 22 - 13
Side c = 15 in
Heron's formula:
s = Perimeter / 2 = 50 / 2
s = 25 in
Area of triangle = √s(s-a)(s-b)(s-c)
Area of triangle = √25(25-22)(25-12)(25-15)
Area of triangle = √25(3)(13)(10)
Area of triangle = 5√390
Area of triangle = 5 × 19(approx)
Area of triangle RST = 95 in² (Approx)
Answer: it’s c
Step-by-step explanation:
Answer:
Step-by-step explanation:
<u>Given the data set of 15 where:</u>
- Mean = 7
- Median = 6
- Mode = 5
- The minimum is 1 and the maximum is 10
<u>As per given we conclude</u>
- The set will have 7 numbers before 6 and 7 numbers after
- Sum of 15 numbers is 15*7 = 105
- The most used number is 5
a) <u>Possible set is:</u>
- 1, 5, 5, 5, 5, 5, 5, 6, 9, 9, 10, 10, 10, 10, 10
b) <u>Add number 20, the set will be:</u>
- 1, 5, 5, 5, 5, 5, 5, 6, 9, 9, 10, 10, 10, 10, 10, 20
<u>The mean is different as we have now more numbers with different sum:</u>
- (105 + 20)/(15 + 1) = 125/16 = 7.8125
<u>The median is different now and moves to the right as 20 added to the far right:</u>
<u>The mode stays same as still most used number is 5:</u>
