gtnhenbr [62]

Answer:

$99\% CI=4.1602 \pm 0.0009$

Step-by-step explanation:

From the question we are told that:

Sample size $n=8$

Mean $\=x=4.1602$

Standard deviation $\sigma=0.001gram$

Generally 99\% confidence from table is mathematically given by

$99\% CI=4.1602 \pm *2.576*\frac{0.001}{\sqrt{{8}}}$

$P(-z$

$Z_{\alpha/2}=2.576$

Generally the equation for 99\% confidence level (CI) is mathematically given by

$99\% CI=\=x \pm Z_{\alpha/2*\frac{\sigma}{\sqrt{{n}}}$

$99\% CI=4.1602 \pm 0.0009$

In an automobile parts factory, for every 175 carburetors 3 are found to be defective. At that rate how many carbureatots out of

Furkat [3]

Answer:

At the same rate 18 carburetors out of 1,050 could be expected to be detective.

Step-by-step explanation:

The number of carburetors tested = 175

Defective pieces out o f 175 = 3

So, ratio of defected to tested = 3 : 175

Now, the number of carburetors tested in second batch = 1,050

Here, let the defective pieces = m

So, by the Ratio of Proportion,

$\frac{3}{175} = \frac{m}{1050}$

or, $m = \frac{1050 \times 3}{175} = 18$

⇒ m = 18

Hence, at the same rate 18 carburetors out of 1,050 could be expected to be detective.

Is 1.7x^2 + 3.5 a cubic polynomial?

devlian [24]

Answer:

No, it is not.

Step-by-step explanation:

This is because if you look at the expression, there is no term that is raised to the cube root. As a result, this isn't a cubic polynomial. However, this would be a quadratic polynomial cause the highest raised exponent is 2, which is the number for quadratic.
