Answer: 1044cm
Step by Step Explanation :
- separate the shape into a rectangle and a square. Subtract 46 from 21
- the rectangular shape is 30cm by 25cm LxW its 750cm
- the smaller shape on the side is 21 cm by 14cm LxW its 294.
- Add. 294cm + 750cm = 1044cm
Hi pupil here's your answer ::
____________________________
The unit rate depicted in the graph is must be
3 laps in 4 minutes . As we can see in the graph that the point meets at the 3 laps and 4 minutes so this option must be suitable for the above question.

Answer:
H0 : μ = 8.5
H1 : μ > 8.5
1 sample t test ;
Test statistic = 2.53
Pvalue = 0.994
No, we fail to reject the Null ;
There is no significant evidence to support the Claim that the mean running time of light bulb is greater Tha last year.
Step-by-step explanation:
H0 : μ = 8.5
H1 : μ > 8.5
Test statistic :
(xbar - μ) ÷ (s/sqrt(n))
(8.7 - 8.5) ÷ (0.5 / sqrt40)
Test statistic = 2.53
The Pvalue :
P(Z < 2.53) = 0.9943
Pvalue = 0.994
Decison region :
Reject H0 ; if Pvalue < α
0.9943 > 0.05 ; We fail to reject the Null
A and E.
