Step-by-step explanation:
3 : x = -7.5
5 : x = -10
6 : x = 12
remaining answers are correct
There is 90 deaths per day.
First it tells us 32,400 people died in 2015, which also mean that many people died that year.
We have to find the number of people died each month first.
32,400÷12 because 12 is the total number of months in a year.
2700 people died in a month, not we need to find how many people died each day so we divided it by 30 and we get
90 deaths per day.
The Given equation is , 3 x + x = 440,
Let speed of train A is x Km/hour and Speed of train B which is a Bullet train which starts from same station but from different platform is 3 times the speed of train A.
And Sum of their Velocities is i.e Velocity of train A and Velocity of train B is 440 Km/hour.
The associated z score for filling to 10.98 oz. is -1.16.
<h3>
Z score</h3>
The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
z = (x - μ) / σ
where x is the raw score, μ is the mean and σ is the standard deviation.
Given that μ = 12.01, σ = 0.89, hence:
For x = 10.98:
z = (10.98 - 12.01)/0.89 = -1.16
The associated z score for filling to 10.98 oz. is -1.16.
