The value of x=4.5
Step-by-step explanation:
4.5+x=9
or, x=9-4.5
or, x=4.5
Answer:
Step-by-step explanation:
In the normal distribution curve, the mean is in the middle and each line to the left and to the right of that mean represent 1- and 1+ the standard deviation. If our mean is 400, then 400 + 50 = 450; 450 + 50 = 500; 500 + 50 = 550. Going from the mean to the left, we subtract the standard deviation and 400 - 50 = 350; 350 - 50 = 300; 300 - 50 = 250. We are interested in the range that falls between 350 and 450 as a percentage. That range represents the two middle sections, each containing 34% of the data. So the total percentage of response times is 68%. We are looking then for 68% of the 144 emergency response times in town. .68(144) = 97.92 or 98 emergencies that have response times of between 350 and 450 seconds.
2X + (2X+10)= 34
Width is 6, Length is 11
6 x 11 is 66
Area is 66
The answer is 12 because the 2 tickets for adult is 4 which equals to 8 and 2 child tickets cost 2 which equal 4 so if u put it together
8+4= 12 so there is ur answer
