I don’t understand how to do this
Simora [160]
It's looking for the measures

m<F + m<G = 180°

(4x)° + (8x)° = 180°

12x = 180°
÷12 ÷12


x = 15

check your work

m<F + m<G = 180°

(4x)° + (8x)° = 180°

4(15)° + 8(15)° = 180°

60° + 120° = 180°

Thompson and Thompson is a steel bolts manufacturing company. Their current steel bolts have a mean diameter of 141 millimeters,
tiny-mole [99]

Answer:

Probability that the sample mean would be greater than 141.4 millimetres is 0.3594.

Step-by-step explanation:

We are given that Thompson and Thompson is a steel bolts manufacturing company. Their current steel bolts have a mean diameter of 141 millimetres, and a standard deviation of 7.

A random sample of 39 steel bolts is selected.

Let \bar X = <u><em>sample mean diameter</em></u>

The z score probability distribution for sample mean is given by;

                            Z  =  \frac{ \bar X-\mu}{\frac{\sigma}{\sqrt{n} }  } }  ~ N(0,1)

where, \mu = population mean diameter = 141 millimetres

           \sigma = standard deviation = 7 millimetres

           n = sample of steel bolts = 39

Now, Percentage the sample mean would be greater than 141.4 millimetres is given by = P(\bar X > 141.4 millimetres)

      P(\bar X > 141.4) = P( \frac{ \bar X-\mu}{\frac{\sigma}{\sqrt{n} }  } } > \frac{141.4-141}{\frac{7}{\sqrt{39} }  } } ) = P(Z > 0.36) = 1 - P(Z \leq 0.36)

                                                            = 1 - 0.6406 = <u>0.3594</u>

The above probability is calculated by looking at the value of x = 0.36 in the z table which has an area of 0.6406.

What is the simplest form of the expression? 3sqrt(24a^10b^6)?
Anastasy [175]

Answer:

\text{The simplest form is }6\sqrt6a^5b^3

Step-by-step explanation:

Given the expression 3sqrt(24a^{10}b^6).

we have to find the simplest form of the expression.

3sqrt(24a^{10}b^6)

=3(24^{\frac{1}{2}}a^{\frac{10}{2}}b^{\frac{6}{2}})

=3(24^{\frac{1}{2}}a^5b^3)

=6\sqrt6a^5b^3

which is the simplest form of the given expression.
