Answer:

[tex] \frac{5}{2} \times \frac{3}{4} \\ \frac{15}{8} [/tex]

Answer:

15/8

Step-by-step explanation:

2.5/2 = 1.25

1.25/2 = 0.625

2.5 - 0.625 = 1.875

1.875 = 75/40 = 15/8

Answer:

The scientist must use 10 ounces of Solution A and 40 ounces of Solution B.

Step-by-step explanation:

Since a scientist has two solutions, which she has labeled Solution A and Solution B, each containing salt, and she knows that Solution A is 40% salt and Solution B is 90% salt, and she wants to obtain 50 ounces of a mixture that is 80% salt, to determine how many ounces of each solution should she use the following calculation must be performed:

100 x 0.9 + 0 x 0.4 = 90

90 x 0.9 + 10 x 0.4 = 85

80 x 0.9 + 20 x 0.4 = 80

50 x 0.8 = 40

Therefore, the scientist must use 10 ounces of Solution A and 40 ounces of Solution B.

Answer:

E(X) = 1.9375

SD(X) = 1.20

Step-by-step explanation:

Let :

G = girl ; B = Boy

P(G) = 0.5 ; P(B) = 0.5

Sample space :

G, BG, BBG, BBBG, BBBBG, BBBBB

Using the multiplication rule of independence :

P(G) = 0.5

P(BG) = 0.5 * 0.5 = 0.25

P(BBG) = 0.5 * 0.5 * 0.5 = 0.125

P(BBBG) = 0.5 * 0.5 * 0.5 * 0.5 = 0.0625

P(BBBBG) = 0.5 * 0.5 * 0.5 * 0.5 * 0.5 = 0.03125

P(BBBBB) = 0.5 * 0.5 * 0.5 * 0.5 * 0.5 = 0.03125

Creating a probability distribution table :

X = 1, 2, 3, 4, 5

For X = 5 ;

P(BBBBG) + P(BBBBB) = 0.03125 + 0.03125 = 0.0625

X :___ 1 ____ 2 ____ 3 _____ 4 _____ 5

P(X) : 0.5 __ 0.25 _ 0.125 _0.0625 _0.0625

The expected value E(X) :

√(ΣX * P(X)) = (1*0.5)+(2*0.25)+(3*0.125)+(4*0.0625)+(5*0.0625) = 1.9375

The standard deviation SD(x) :

√(ΣX²*p(x) - E(X)²

√((1^2*0.5)+(2^2*0.25)+(3^2*0.125)+(4^2*0.0625)+(5^2*0.0625) - 1.9375^2)

√(5.1875 - 3.75390625)

√1.43359375

SD(X) = 1.197

SD(X) = 1.20

Answer

In standard form, the equation is y=4|x+16|+2

Step-by-step explanation:

I included a graph as well

The requried solution of the given expression is y = 6 and -2.

The equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.

here,

Simplifying the equation as to form standard form.
4|y - 2| - 16 = 0
4|y - 2| = 16
y - 2 = ± 4,

Now,
y - 2 = 4         ; y - 2 = - 4
y = 6              ; y = -2

Thus, the requried solution of the given expression is y = 6 and -2.

A line of best fit guides a line through a scatter plot of data points that best describes the association between those points.

A line of best fit guides a line through a scatter plot of data points that best describes the association between those points. Statisticians typically utilize the least squares approach to arrive at the geometric equation for the line, either through manual computations or regression analysis software.

A line of best fit can be approximately specified utilizing an eyeball the method by marking a straight line on a scatter plot so that the numeral of points above the line and below the line stands about equal (and the line passes via as many points as possible).

Answer:

Step-by-step explanation:

Answer: ~31.3

first use the pythagorean theorem. a^2+(40)^2=50^2.

simply. a+1600=2500. subtract 1600 from both sides. a^2=900.

square root both sides to get a= 30

then find how far the top of the ladder is from the ground once in its new position.

a^2+(39)^2=50^2.

simplify. a^2+1512=2500. subtract 1512 from both sides to get a^2=979.

square root both sides to get a=31.288975. round to the nearest tenth to get a=31.3

Answer:

216 times the original

Step-by-step explanation:

Volume 1 = 4/3 πr³

volume 2 = 4/3 π(6r)³

v 2 / v 1 = 6³ = 216

When the radius of a sphere is multiplied by 6, the volume is multiplied by 216

Let the radius of the sphere be r

The volume of a sphere of radius, r is calculated as:

v = 4/3 πr³

When multiplied by 6, the radius becomes:

R = 6r

The new volume is then calculated as:

V = 4/3 π(6r)³

Divide both volumes

V/v = 4/3 π(6r)³ / 4/3 πr³

Evaluate the quotient

V/v = 6³

V/v = 216

Hence, when the radius of a sphere is multiplied by 6, the volume is multiplied by 216

Answer:

25.50 is the final price

Step-by-step explanation:

First find the new price at 15% off

59.99 * 15%

59.99 * .15

9.00

Subtract 9 dollars from the price

59.99-9.00

50.99

Now take 50% off

50.99 * 50%

50.99*.50

25.50

50.99-25.50

25.50

Answer:  82

Step-by-step explanation:

As we know remainder formula:-

 Dividend = Quotient × Divisor + Remainder

Here, dividend = Two digits number & divisor = Sum of digits

m + 10n = 8 × (m + n) + 2

 m + 10n = 8m + 8n + 2

 m - 8m + 10n - 8n = 2

 2n - 7m = 2

  2n = 7m + 2

 n = (7m + 2)/2 - -  (Eq.1)

Digits interchanged, two digits number is divided by sum of digits, quotient is 2 & remainder is 8.

Now, when digits interchanged:-

 Two digits number = 10m + n

Using same formula we get:-

 10m + n = 2 × (m + n) + 8

10m + n = 2m + 2n + 8

 10m - 2m + n - 2n = 8

 8m - n = 8

 8m = n + 8

 n = 8m - 8 - - - (Eq.2)

Comparing both equations:-

 (7m + 2)/2 = 8m - 8

 7m + 2 = 2(8m - 8)

 7m + 2 = 16m - 16

 7m - 16m = -16 - 2

 -9m = -18

 m = -18/-9

 m = 2

So, digit at unit's place = 2

Put this value in (Eq.2)

n = 8(2) - 8

n = 16 - 8

n = 8

So, digit at ten's place = 8

Now two digit number:-

 Two digit number = 2 + 10(8)

 Two digit number = 2 + 80

Two digit number = 82
