A division problem divides a 3-digit number by a 1 digit number. The quotient is 307 r3. What could the division problem be?

Tanya [424]

Answer:

There is no solution to this problem.

Step-by-step explanation:

The 1 digit number cannot be 1, since there would be no remainder.

The 1 digit number cannot be 2, since the remainder could be 0 or 1.

The 1 digit number cannot be 3, since the remainder could be 0, 1, or 2.

So, the 1 digit number must be greater than 3. Let's start with 4. Since the quotient is 307 (remainder 3), 4 x 307 is already more than 3 digits.

A lab is testing the amount of a certain active chemical compound in a particular drug that has been recently developed. The man

Mazyrski [523]

Answer:

The 95% confidence interval is "87.94, 91.86".

Step-by-step explanation:

The given values are:

Sample batches,

n = 25

Sample mean concentration,

$\bar{x}$ = 89.9 mg

Amount of chemical,

σ = 5

α = 0.05

The critical value from Z table will be:

= $Z(\frac{\alpha}{2} )$

= $Z(\frac{0.05}{2} )$

= $1.96$

Now,

The confidence interval will be:

= $\bar{x} \pm Z(\frac{\alpha}{2} )\times \frac{\sigma}{\sqrt{n} }$

On substituting the values, we get

= $89.9 \pm Z(\frac{0.05}{2})\times \frac{5}{\sqrt{25}}$

= $89.9 \pm Z(\frac{0.05}{2})\times \frac{5}{5}$

= $89.9 \pm1.96\times 1$

Lower limit will be:

= $89.9 -1.96\times 1$

= $87.94$

Upper limit will be:

= $89.9 +1.96\times 1$

= $91.86$
