Answer:

Johnny needs to score 98 on third test to raise average to 94

Step-by-step explanation:

Given that average of two tests is 92.

The score of next test has to be found that means there will be a total of 3 tests.

The average will be:

[tex]Avg = \frac{test1+test2+test3}{3}[/tex]

It is also given that he has to raise his average to 98

We have to use the average formula for finding the third value

So,

[tex]94 = \frac{92+92+test3}{3}\\94*3 = 184+test3\\282 = 184+test3\\test3 = 282-184\\test3 = 98[/tex]

Hence,

Johnny needs to score 98 on third test to raise average to 94

Answer:

Johnny would need to get a 98

Step-by-step explanation:

You would need to use the average formula and see what it would be eual to.

2s = 38

2s + 6 = 44

Step-by-step explanation:

Given parameters:

Length of the board  = 44inches

Unknown:

equation to find the shorter piece s = ?

Solution:

 let the longer piece  = L

 Shorter piece  = s

s + L = 44 ---- i

Now,

   L  = s + 6 ----- ii

put L  = s + 6 into i;

  s  + s + 6  = 44

     2s + 6  = 44

    2s  = 44 - 6

    2s  = 38

Answer:

$15,059

Step-by-step explanation:

4.1 x 9 = 36.9

36.9% of 11,000 = 4059

11,000 + 4,059 = 15,059

The value of the investement after 9 years ompounded continuously is .$15792.44

Compound interest is the interest on an amount of money invested

The formula for calculating compound interest is expressed as:

A =P(1+r)^n

Given

P = 11000
r = 4.1% = 0.041

n = 1

t =9 years

Substitute

A = 11000(1+0.041)^9
A = 11000(1.041)^9
A= .$15792.44

Hence the value of the investement after 9 years ompounded continuously is .$15792.44

Answer:

a) the probability that  no sales are made in 10 calls is 0.1969

b) the probability more than 1 sales are made in 20calls is 0.8244

Step-by-step explanation:

Given that;

p = 0.15

q = 1 - p = 1 - 0.15 = 0.85

a) probability that  no sales are made in 10 calls will be;

n = 10

p(x=0) = ¹⁰C₀(0.15)⁰ (0.85)¹⁰ = 0.1969

Therefore the probability that  no sales are made in 10 calls is 0.1969

b) probability more than 1 sales are made in 20calls

n = 20

let y be number of sales in 20 calls

y∪Bin(n=20, p=0.15)

p(y > 1) = 1 - [p(y=0) + p(y=1)

= 1 - [²⁰C₀(0.15)⁰ (0.85)²⁰ + ²⁰C₁(0.15) (0.85)¹⁹] = 0.8244

Therefore the probability more than 1 sales are made in 20calls is 0.8244

Answer:

a. Bank A

b. 8,670 Kroner

Step-by-step explanation:

a. The bank that will give Mia a better exchange rate is the Bank who's exchange rate is higher in value, that is has more units of Kroner per $1.

Let's find which Bank has the best exchange rate.

Using the pair, (100, 510),

Bank A exchange rate = [tex] \frac{510}{100} = 5.1 [/tex]

Bank A exchange rate is 5.1 kroner per dollar

Using the point, (10, 50) on the graph,

Bank B exchange rate = [tex] \frac{50}{10} = 5 [/tex]

Bank B exchange rate is 5.0 kroner per dollar.

✅Therefore, Bank A has a better exchange rate.

Mia will get more Kroner per each dollar she wants to exchange if she lots for Bank A.

b. If Mia exchanged her $1,700 at Bank A, she would get:

1,700 × 5.1 = 8,670 Kroner.

a) The bank A have the best exchange rate.

b) Mia will receive an addition of 1303,90 crowns with the better exchange rate.

a) Given the existence of linear relationship between the amount of dollars ([tex]x[/tex]) and the expected amount of crowns ([tex]y[/tex]), the exchange rate ([tex]r[/tex]) is represented by the slope of each line, which is determined by definition of secant line.  The greater the slope, the better the exchange rate.

Now we proceed the exchange rate for each bank:

Bank A

[tex]r_{A} = \frac{612-408}{120 - 80}[/tex]

[tex]r_{A} = 5.1\,\frac{DKC}{USD}[/tex]

Bank B

[tex]r_{B} = \frac{130 - 0}{30 - 0}[/tex]

[tex]r_{B} = 4.333\,\frac{DKC}{USD}[/tex]

The bank A have the best exchange rate.

b) The addition ([tex]\Delta y[/tex]), in crowns, is defined by the following formula:

[tex]\Delta y = (r_{A}-r_{B})\cdot x[/tex] (1)

If we know that [tex]r_{A} = 5.1\,\frac{DKC}{USD}[/tex], [tex]r_{B} = 4.333\,\frac{DKC}{USD}[/tex] and [tex]x = 1700\,USD[/tex], then the addition is:

[tex]\Delta y = (5.1-4.333)\cdot 1700[/tex]

[tex]\Delta y = 1303,90\,DKC[/tex]

Mia will receive an addition of 1303,90 crowns with the better exchange rate.

AB(6;-12)

Step-by-step explanation:

The length of AB is 10 units.

A line segment is a subset of a line which has two end points.Distance of a given line segment with two endpoints and a pair of co-ordinates can be obtained by [tex]\sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2 }[/tex] this formula know as distance formula.

According to the given question co-ordinate of two points are given and we have to find the distance.

We know that distance between two points is given by  

[tex]\sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2 }[/tex]

Here A = (x₁,y₁) = (-2,10) and B = (x₂,y₂) = (4,-2).

∴ AB = [tex]\sqrt {\left( {-2 - 4 } \right)^2 + \left( {10 -2 } \right)^2 }[/tex].

AB = [tex]\sqrt {\left( {-6} \right)^2 + \left( {8 } \right)^2 }[/tex]

AB = [tex]\sqrt {\left( {36} \right) + \left( {64} \right) }[/tex]

AB = [tex]\sqrt {100}[/tex]

AB = 10 units.

Answer:

28

Step-by-step explanation:

If the area is 48. 48 divided by 6 is 8 right? Okay then, two sides of the rectangle is going to be 8 and 2 sides of the rectangle is going to be 6.

So, take 8+8 and 6+6 which equal 28.

remember, to find the perimeter you add.

which concludes the answer to be 28.

Answer:

28 units

Step-by-step explanation:

So to find the perimeter, you need to find the other length of the triangle. To find that, let's look at the area that was given. We know that area = L x W. So we have the width and when we divide it by the area we can find the missing length which should be: 48/6=8

So with both the length of 8 and the width of 6, we can find the perimeter is equal to:

Perimeter= 8 + 8 + 6 + 6

Perimeter=28

Answer:

[tex]y[/tex] is decreasing by 10 units per second.

Step-by-step explanation:

Given information:

The particle moves on the hyperbola [tex]xy=15[/tex]

Time [tex]t\geq 0[/tex]

Now at a certain instant , [tex]x=3[/tex] and [tex]\frac{dx}{dt} = 6[/tex]

Now, Differentiating [tex]xy=15[/tex] with respect to [tex]t[/tex]

We get:

[tex]x.\frac{dy}{dt} +y.\frac{dx}{dt} =0[/tex]

Now substitute the values in above equation:

[tex]3\frac{dy}{dt}+ 5 \times 6=0[/tex]

[tex]3 \frac{dy}{dt}=-30\\\frac{dy}{dt} =-10[/tex]

The negative sign indicates that [tex]y[/tex] is decreasing by 10 units per second.
