Total earning in the summer = $1440
Step-by-step explanation:
Earning per hour for Samuel = $7.50
No. of hours worked in a day = 6
Earning for a day = Earning per hour for Samuel *No. of hours worked in a day
Earning for a day = $7.50 *6 = $45
___________________________________________________
No of days worked in a week by Samuel = 4
Earning for week = Earning for a day *No of days worked in a week by Samuel
Earning for week = $45*4 = $180
_____________________________________________________
No. of weeks worked in summer = 8
Total earning in the summer = Earning for week *No. of weeks worked in summer
Total earning in the summer = $180*8 = $1440 (Answer)

A chocolate factory produces mints that weigh 10 grams apiece. The standard deviation of the weight of a box of 10 mints is 3 gr
frozen [14]

The confidence that the box you bought did not come from the factory is 90 %.

<u>Step-by-step explanation:</u>

Since we have given that

Population Mean weight (\mu)= 10 grams a piece

Standard deviation of the weight of a box = 3 grams

Number of mints = 10

We need to buy a box of mints that weighs 95 grams.

Sample mean is given by

x = \frac{95}{10}=9.5 grams .

First we find out the standard error which is given by

s=\frac{\sigma}{\sqrt{n}}\\\\=\frac{3}{\sqrt{10}}\\\\= 0.94868

Since it is normal distribution, so, we will find z-score.

z=\frac{x-\mu}{s}\\\\z=\frac{9.5-10}{0.94868}\\\\z=-0.527\\\\

z = - 0.53

The area to the left of a z-score of -0.53 = 0.29805.

So, it may be 90% or 95 % confidence.

For 95% confidence level,

\alpha=\frac{1-0.95}{2}=0.025

Similarly,

For 90% confidence level,

\alpha=\frac{1-0.90}{2}=0.05

The value is much smaller than 0.05.  

So, we will get 90% confidence and the critical value = 1.645

Margin of error is given by

(Standard deviation) \times (critical\ value) = 0.94868 \times 1.645

                                                              =1.56

So, confidence interval will be

                          (10-1.56,10+1.56)

                              =(8.44,11.56)

Find the value of x in the triangle shown below.
MissTica

Answer:

x =  \sqrt{17}

Step-by-step explanation:

By Pythagoras Theorem:

x =  \sqrt{ {9}^{2}  -  {8}^{2} }  \\  \\ x =  \sqrt{81 - 64}  \\  \\ x =  \sqrt{17}

In the diagram above of ADB where angle B is a right angle. Determine the length of DC to the nearest whole number.
timama [110]

Use tan(angle) = opposite leg/ adjacent leg

BC = tan(45) = x/100

X = tan(45) x 100

X = 100

BD = tan(60) = x/100

X = tan(60) x 100

X = 173

DC = BD - BC = 173-100 = 73

DC = 73
