<h2>Answer with explanation:</h2>

Given : A random sample of five Galaxy 8 smartphones is selected from the production line after final assembly, and the result of the weight control measurement is (in grams) are :

X= 155.1, 154.8, 155.5, 155.3, and 154.6.

here, n=5

The average weight : $\overline{x}=\dfrac{\sum^{i=5}_{i=1}x_i}{n}$

$=\dfrac{155.1+154.8+155.5+155.3+154.6}{5}\\\\=\dfrac{775.3}{5}=155.06$

∴ Average weight ( $\overline{x}$ )=155.06 grams

Uncertainty = Standard deviation: $\sigma=\sqrt{\dfrac{\sum^{i=5}_{i=1}(x_i-\overline{x})^2}{n}}$

$=\sqrt{\dfrac{(0.04)^2+(-0.26)^2+(0.44)^2+(0.24)^2+(-0.46)^2}{5}}$

$=\sqrt{\dfrac{0.532}{5}}=\sqrt{0.1064}=0.326190128606\approx0.33$

i.e. Its uncertainty : $\sigma=0.33$

The fractional uncertainty = $\dfrac{\sigma}{\overline{x}}$

$=\dfrac{0.33}{155.06}=0.00212820843544\approx0.002$

Mimi sells super-sized cookies for $1.50 each and estimates she has expenses of $10 to make one batch of cookies. If the inequal

Jobisdone [24]

Answer:

(b) x > 26 cookies

Step-by-step explanation:

The selling price of 1 super-sized cookie, S.P.=$1.50

Let a batch have x cookies.

So, the selling price of x cookies=1.5x

The expences in making one batch of cookies=$10

So, net profit = 1.5x-10

The given inequality to model this is 1.5x - 10 > y, That means the profit for one batch is greater than y.

As she wants to make a profit of at least $30, so for this condition, the value of y is 30.

Now, the given inequality become,

$1.5x - 10 >30$

$\Rightarrow 1.5x>30+10$

$\Rightarrow x>\frac{40}{1.5}$

$\Rightarrow x>26\frac{2}{3}$

As x is the number of cookies, so, it can't have a fractional value. This can be written as

$x>26$ or $x\geq27.$

So, she has to sell more than 26 cookies to make a profit of at least $30.

Hence, option (b) is correct.
