Answer:

£9.90

Step-by-step explanation:

There are 2 ways you can do this. Both are similar.

For the first method it's much quicker but you might need a calculator.

You would simply do 7.5 × 1.32 = £9.90 that should give you the answer.

If you were to do it with out a calculator then what you need to do is 7 × 1.32 = 9.24

Because there is still 0.5 (or 1/2) left from the 7 that you multiplied, you do 1.32 ÷ 2 = 0.66.

Add the 2 numbers together

0.66 + 9.24 = £9.90

The length of time needed to complete a certain test is normally distributed with mean 46 minutes and standard deviation 6 minut

madam [21]

Answer:

0.0668 or 6.68%

Step-by-step explanation:

Mean time (μ)= 46 minutes

Standard deviation (σ) = 6 minutes

The z-score for any given time X is determined by:

$z=\frac{X-\mu}{\sigma}$

For X = 37:

$z=\frac{37-46}{6}\\ z=-1.5$

A z-score of -1.5 corresponds to the 6.68th percentile of a normal distribution. The probability that it will take less than 37 minutes to complete the test is

$P(X\leq 37) = 0.0668=6.68\%$

The probability is 0.0668 or 6.68%

Solve the equation. Round the solution to the nearest tenth . Enter the solution set of the equation . 2P o =P 0 (1.053)^ t

kow [346]

Answer: t= 13.4

Step-by-step explanation:

The given equation is $2P_0=P_0(1.053)^t$

To solve this equation for 't', we first divide both sides by $P_0$ , we get

$2=(1.053)^t$

Taking log on both the sides, we get

$\log 2= \log(1.053)^t$

Since $\log a^b=b\log a$

Then,

$\log 2= t\log1.053\\\\\Rightarrow0.30103=t(0.02243)\\\\\Rightarrow t=\dfrac{0.30103}{0.02243}\\\\\Rightarrow t=13.4208649131\approx13.4$

Hence, the value of t is 13.4.
