Gurnaz has been mowing lawns to save money for a concert. Gurnaz will need to work for at least six hours to save enough money,
inessss [21]

Answer:

The required inequality is: 6\leq x

Step-by-step explanation:

Consider the provided information.

Gurnaz has been mowing lawns to save money for a concert. Gurnaz will need to work for at least six hours to save enough money, but he must work fewer than 16 hours this week.

Let the number of hours Gurnaz work is represented by x.

Gurnaz will need to work for at least six hours to save enough money,

That means he can work 6 or more than 6 hours,

x\geq 6

He must work fewer than 16 hours this week. That means the value of x should be less than 16.

x

Thus, the required inequality is: 6\leq x

Now draw the graph of the inequality.

Use a dot or close circle to represents ≤ or ≥ and use a open circle to represent < or >.

The value of x is greater than or equal to 6 also the value of x is less than 16. The required graph is shown below.

There is a 0.9991 probability that a randomly selected 31​-year-old male lives through the year. A life insurance company charge
jarptica [38.1K]

Answer:

a) Monetary values corresponding to the two events are:

-In case of surviving the year = -166$

-In case of a death in the year = 89834$

b) Expected value of the purchasing the insurance is -85 $

c) Yes, insurance company can make a profit with this policy.

Step-by-step explanation:

<em>a)</em> The man need to pay 166$ first to enroll the insurance policy. If he survives within a year, he will lose 166$. Otherwise, if he dies within a year he will profit 89834$.

<em>b)</em> Expected value of the purchasing the insurance as following:

<u>-In case of surviving the year: </u>

Value: -166$

Probability: 0,9991

<u>-In case of death in a year </u>

Value: 89834$

Probability: 0,0009

Expected value is E(x) = -166×0,9991 + 89834×0,0009 = -85 $

<em>c)</em> Lets consider that 10000 different 31 year old man enrolled to this insurance policy. According to probability of death, 9 out of 10000 man expected to be dead within the year. Therefore, company need to pay 9*90000 = 810000$ to their costumers. But, company will collect 10000*166=1660000$ from their costumers in the beginning of the year

So, it is expected that company is going to profit 1660000-810000=850000$ per year.

Please help with geomtry

Angle ADB is a right angle, which is given.

The measure of ADB is 90 degrees by definition of right angle.

The two angles are a linear pair (aka they're supplementary) by definition of linear pair (they're formed by two intersecting lines).

The measure of BDC is 90 because BDC + ADB = 180 (definition of linear pair), and ADB = 90 (given).

BDC = ADB because 90 = 90


Overall, the two triangles are congruent by SAS.

Need a bit of help with this​
natali 33 [55]

Answer:

<h2>∠HFG = 115°</h2>

Step-by-step explanation:

∠JFG + ∠HJF = 180° <em>[Adjacent angles of parallelogram are supplementary] </em>

<em>∠</em>JFG = 65°

=> 65° + ∠HJF = 180°

=> ∠HFG = 180° - 65°

=> ∠HFG = 115°
