Answer:
the first choice
Step-by-step explanation:
-0.8 is the smallest number considering it is negative.
-1/3 is negative too, but it is not as much at -0.8 since when reduced to a decimal, it's would be -0.3334 (rounding up).
2/3 is not as much as 1 since it is not a whole number.
1 is the biggest number in the graph.
Answer:
Step-by-step explanation:
Given the following scores 3, 7 and 2, we are to find the expression Σ2X-2 and Σ(X-1)²
The value of X's are 3, 7 and 2. Substituting the values we will have;
Σ2X-2 = [2(3)+2(7)+2(2)] - 2
Σ2X-2 = (6+14+4) - 2
Σ2X-2 = 24-2
Σ2X-2 = 22
For Σ(X-1)²
Σ(X-1)² = (3-1)²+ (7-1)² + (2-1)²
Σ(X-1)² = 2²+6²+1²
Σ(X-1)² = 4+ 36+1
Σ(X-1)² = 41
Answer:
2:3=14:21
Step-by-step explanation:
2+2=5
35/5=7
7*2=14
7*3=21
Martina runs 10.5 miles in 75 minutes
<em><u>Solution:</u></em>
Given that,
Martina runs 7 miles in 50 minutes
<em><u>Therefore, miles ran in 1 minute is:</u></em>

At the same rate how many miles will she run in 75 mins
<em><u>Thus, to find the miles ran in 75 minutes:</u></em>

Thus she runs 10.5 miles in 75 minutes
