PLEASE GIVE ME AN ANSWER QUICKLY! Hiroshi spends 30 minutes on history homework , 60 minutes on English homework, and x minutes

natka813 [3]

Answer:

Step-by-step explanation:

He spends:
30 mins on History
60 mins on English
x mins on math
so the total time he spends is $(TotalTime)minutes=(30+60+x)minutes$
one fourth of this is his math time, since x is math time, then we have $\frac{1}{4}(TotalTime)minutes=(x)minutes$
But we know what totaltime in minutes is so $\frac{1}{4}(30+60+x)minutes=(x)minutes$
or simply: $\frac{1}{4}(30+60+x)=x$

What is the relation between the variables in the equation y/x^2=10

Slav-nsk [51]

The given expression is:

$\frac{y}{ x^{2} } =10$

which gives:

$y = 10x^{2}$

This implies that y and x^2 have an inverse relationship and "10" is the constant term in this expression.

Assume that blood pressure readings are normally distributed with a mean of 124 and a standard deviation of 6.4. If 64 people ar

Murrr4er [49]

Answer:

99.38%

Step-by-step explanation:

We have that the mean (m) is equal to 124, the standard deviation (sd) 6.4 and the sample size (n) = 64

They ask us for P (x <126)

For this, the first thing is to calculate z, which is given by the following equation:

z = (x - m) / (sd / (n ^ 1/2))

We have all these values, replacing we have:

z = (126 - 124) / (6.4 / (64 ^ 1/2))

z = 2.5

With the normal distribution table (attached), we have that at that value, the probability is:

P (z <2.5) = 0.9938

The probability is 99.38%
