When the measure of two vertical angles are 8x-18 and 6x+14, x is A. 16.

It should be noted that vertically opposite angles are equal. In this case, we have to equate both angles given. This will be illustrated as:

Angle 1 = Angle 2

8x - 18 = 6x + 14

Collect like terms

8x - 6x = 14 + 18

2x = 32

Divide

x = 32/2

x = 16

The value of x is 16.

Answer: 11.2

Step-by-step explanation: In order to find the length of n, you can use the given angle measure and base length as well as a trig ratio. Since 6.2 is adjacent to angle N, you can use tangent (opposite/ adjacent).

tan (61) = n/6.2

(multiply by 6.2 on both sides to isolate n)

• 6.2 • 6.2

tan (61) • 6.2 = n

11.185 = n

~11.2 = n.

The measure of the angle indicated is as follows:

The measure of the angle indicated can be found using exterior angle theorem. The exterior angle theorem states that  If a side of a triangle is produced, then the exterior angle so formed is equal to the sum of the two interior opposite angles.

Therefore,

m∠S + m∠T = 129

m∠S  = -3 + 6x

m∠T = 11x + 13

Therefore,

129 = - 3 + 6x + 11x + 13

129 = - 3 + 13 + 6x + 11x

129 = 10 + 17x

129 - 10 = 17x

119 = 17x

x = 119 / 17

x = 7

Therefore,

m∠S = - 3 + 6(7) = -3 + 42 = 39°

A confidence interval in frequentist statistics is a range of estimates for an unknown parameter. A confidence interval is calculated at a specified degree of confidence; the most popular level is 95%, but other levels, such 90% or 99%, are occasionally used. Confidence intervals are used by statisticians to assess a sample variable's level of uncertainty. For instance, a researcher might randomly select many samples from the same population, compute a confidence interval for each sample, and then examine how well each sample might reflect the true value of the population variable. The generated datasets are all unique, some of which contain the genuine population parameter and others which do not. An unknown population parameter is most likely to be found inside a range of values that is bounded above and below the statistic's mean.

The amount of litres he consume is 26 litres.

He spent a total of €37,70 for 26 litres.

He can buy 40 litres of petrol for € 58

He fills up his car which is 60 litres.

After a certain distance, 340 decilitres remained in the tank.

Therefore, we have to convert the amount of gas remaining in the car to litres.

Hence,

1 decilitres = 0.1 litres

340 decilitres  = ?

cross multiply

amount of petrol remaining in the car = 0.1 × 340

amount of petrol remaining in the car = 34 litres

Therefore,

amount of litres consumed = 60 - 34 = 26 litres.

Let's find the cost he spent if 1 litre cost € 1.45.

1 litre = € 1.45

26 litres = ?

amount spent  = 26 × 1.45

amount spent = € 37.70

Let's find how many litres of petrol he can buy for € 58.

€ 1.45 = 1 litre

€ 58 = ?

cross multiply

number of litres he can buy with € 58 = 58 / 1.45

Therefore,

number of litres he can buy with € 58 = 40 litres.

The length of the segment  BZ is approximately 2.78

The above value is obtained by using the following process:

The given parameters of the triangle are;

The angle bisectors of the triangle = BY and CZ

The point at which BY and CZ meet = The point I

The length of CY = 4

The length of AY = 6

The length of AB = 8

The unknown parameter;

The length of the segment BZ

Method:

Apply the angle bisector theorem

According to the angle bisector theorem we have;

AY/CY = AB/BC

BZ/AZ = BC/AC

From AY/CY = AB/BC,  we get;

6/4 = 8/BC

6 × BC = 8 × 4 = 32

BC = 32/6 = 16/3 =  5.33

BC = 5.33

From BZ/AZ = BC/AC, we have;

AC = CY + AY

∴ AC = 4 + 6 = 10

AZ = AB - BZ

∴ AZ = 8 - BZ

Therefore;

BZ/8 - BZ = 5.33/10

10 × BZ =  ×(8 - BZ) = (16/3) × 8 -  (16/3)·BZ

10·BZ + (16/3)·BZ = (16/3) × 8

(46/3)·BZ = 128/3

BZ = 128/46 = 64/23

Length of the line BZ = 64/23 = 2 ≈ 2.78

Therefore, the length of the segment  BZ is approximately 2.78.

T-Mobile charges a base fee of $15 per month plus $0.05 for each minute. 300 minutes long would you need to call for them to charge the same amount.

Given: While Verizon has a basic rate of only $10 per month but charges $0.10 for long-distance calls, T-Mobile has a base fee of $15 per month plus $0.05 for each minute you are on the phone.

We have to estimate how long would you need to call for them to charge the same amount.

Let the equation be 15 + 0.05 x = 0.10 x

⇒ 0.05 x - 0.10 x = -15

simplifying the above equation, we get

⇒ -0.05 x = -15

⇒ 0.05x = 15

⇒ x = 15 / 0.05

⇒ x = 300 minutes

Therefore, 300 minutes long would you need to call for them to charge the same amount.

Considering Annie bought 5 pounds of apples, 4 pounds of oranges, and 3 pounds of bananas, and each pound of apple costed $1.75, orange $2.35 and bananas $1.50,

(i) Annie had to spend an exact amount of $22.65, to buy all the above mentioned fruits.

(ii) The amount of money that Annie spent on the fruits, can be represented by the expression [(1.75 * 5) + (2.35 * 4) + (1.50 * 3)]

(iii) Rounding the prices to the nearest whole dollar and estimating the total amount Annie spent, our estimation is an overestimation compared to the actual price Annie had spent.

As per the question statement, no information is provided about Annie's expenditure, and hence, we are considering that, Annie bought 5 pounds of apples, each pound costing $1.75, 4 pounds of oranges, each pound costing $2.35 and 3 pounds of bananas, each pound costing $1.50.

We are required to calculate:

(i) The exact amount Annie spent on the fruits.

(ii) A mathematical expression to represent the amount of money that Annie spent.

(iii) To determine whether it is an overestimation or underestimation if we round the prices to the nearest whole dollar and estimate the total amount Annie spent.

Starting with (i) and (ii),

Total amount Annie actually spent on her fruits

= [{(price of per pound apple) * (number of pounds of apple she bought)} + {(price of per pound orange) * (number of pounds of orange she bought)} + {(price of per pound banana) * (number of pounds of bananas she bought)}

= $[(1.75 * 5) + (2.35 * 4) + (1.50 * 3)]

= $(8.75 + 9.40 + 4.50)

= $22.65

And, the amount of money that Annie spent on the fruits, can be represented by the expression [(1.75 * 5) + (2.35 * 4) + (1.50 * 3)].

Now solving (iii), first, we need to round off the prices to the nearest whole dollar and then estimate the total amount Annie spent.

Now, $1.75 dollars rounded off the prices to the nearest whole dollar will become $2.

Similarly, $2.35 dollars rounded off the prices to the nearest whole dollar will become $2,

And, $1.50 dollars rounded off the prices to the nearest whole dollar will become $2.

That is, the rounded-off per pound cost of apples is $2, that of oranges is $2 and of bananas is also $2.

Therefore, on the same consideration that, Annie bought 5 pounds of apples, 4 pounds of oranges, and 3 pounds of bananas, the estimated total amount she spent on the fruits based on the above mentioned rounded-off per pound costs will be equal to

$[(2 * 5) + (2 * 4) + (2 * 3)] = ${10 + 8 +6) = $24

Since (24 > 22.60), thus, we can conclude that rounding-off the prices to the nearest whole dollar and estimating the total amount Annie spent, our estimation is an overestimation compared to the actual price Annie had spent.

The expression f(5)=10 tells us that if Polly is an artist and sells posters at a local cafe then it means that Polly makes 10 dollars when she sells 5 posters.

According to the question,

We have the following information:

Polly sells x posters then she makes f(x) dollars.

We have the following expression:

f(5) = 10

So, it simply means that in place of x in f(x) we have f(5) then we have 5 in place of x.

f(x) is the amount made in dollars. So, the total amount Polly made is 10 dollars.
