On a biased dice the probability of getting a 6 is 4/5 the dice is rolled 500 times how many sixes would you expect to roll

Answer:

Step-by-step explanation:

[tex]h(t)=-16t^2+v_0t+h_0[/tex] where

h(t) is the height of the ball after a certain amount of time has gone by,

-16t² is the pull of gravity in ft/s/s,

v₀t is the initial upwards velocity, and

h₀ is the height from which the ball was initially thrown. Our equation is then, filling in the info in the correct places:

[tex]h(t)=-16t^2+128t+4[/tex] where 128 is the given initial velocity and 4 is the number of feet from which the ball was initially launched.

Step-by-step explanation:

64,872 rounded to the nearest hundred should be 64,900

Answer:

64900

Step-by-step explanation:

Look at number after hundred's place

if its 5 or higher round up

if its 4 or less round down

The coordinate of the point  on the directed line segment that partitions the segment into a ratio of 4 to 3 is (29/7,50/7)

The given parameters are:

A = (-1,6)

B = (8,8)

Ratio, m : n = 4 : 3

The coordinate at the partition is calculated using:

[tex](x,y) = \frac{1}{m + n} * (mx_2 + nx_1,my_2 + ny_1)[/tex]

So, we have:

[tex](x,y) = \frac{1}{4 + 3} * (4 * 8 + 3 * -1,4 *8 + 3 * 6)[/tex]

Evaluate

[tex](x,y) = \frac{1}{7} * (29,50)[/tex]

Evaluate the product

(x,y) = (29/7,50/7)

Hence, the coordinate of the point is (29/7,50/7)

Answer:

[tex]9 - 4\sqrt{2}[/tex]

Step-by-step explanation:

sin60° = [tex]\frac{\sqrt{3} }{2}[/tex]

tan60° = [tex]\sqrt{3}[/tex]

tan45° = 1

cos45° = [tex]\frac{1}{\sqrt{2} }[/tex]

(2sin60°)(3tan60°) - (4tan45°)(2cos45°)

now substitute the values of each trigonometrical angles

[tex](2*\frac{\sqrt{3} }{2} )(3*\sqrt{3} ) - (4*1)(2*\frac{1}{\sqrt{2} } )[/tex]

[tex]\sqrt{3} * (3\sqrt{3}) - 4*(\frac{2}{\sqrt{2} } )[/tex]

Answer:

190 square inches

Step-by-step explanation:

Surface area of a rectangular prism formula is given as

2(LW + LH + WH)

Where

L = Length = 5in

H = Height = 3in

W = Width = 10in

Hence:

Surface area = 2(5 × 10 + 5 × 3 + 3 × 10) square inches

= 2 × (50 + 15 + 30) square inches

= 2 × (95) square inches

= 190 square inches

Therefore, the surface area of Erin's jewelry box is 190 square inches

=========================================================

Explanation:

The mixed number 7 & 1/4 converts to the decimal form 7.25, since 1/4 = 0.25

The ratio 1:7.25 means that we'll multiply the smaller triangle's sides by the scale factor 7.25 to get the larger corresponding side

Meaning that the value of x is 3*7.25 = 21.75

This converts to the mixed number 21 & 3/4

Answer:

sinA = - [tex]\frac{\sqrt{5} }{\sqrt{6} }[/tex]

Step-by-step explanation:

Given

tanA = - [tex]\frac{\sqrt{5} }{1}[/tex] = [tex]\frac{opposite}{adjacent}[/tex]

This is a right triangle with opposite = [tex]\sqrt{5}[/tex], adjacent = 1 and

hypotenuse h² = ([tex]\sqrt{5}[/tex] )² + 1² = 5 + 1 = 6 ⇒ h = [tex]\sqrt{6}[/tex]

Since tanA < 0 and cosA > 0 then A is in the 4th quadrant where sinA < 0

Then

sinA = - [tex]\frac{opposite}{hypotenuse}[/tex] = - [tex]\frac{\sqrt{5} }{\sqrt{6} }[/tex]

Answer:

A≈842.53

Volume = side³

=> 1664 = side³

=> ³√1664 = side

=> 4 (³√26) = side

=> 4 (26^1/3) = side

Surface area = 6 side²

=> Surface area = 6 × [4 (26^1/3)]²

=> Surface area = 6 × 140.42 [approximately]

=> Surface area = 842.54 [approximately]

Answer:

55

Step-by-step explanation:

55 has both its tens and units the same and when you reverse it, it is still 55 hence 55+55 is 110

Given : The tens and units digit of the number are the same

Let the given number be : NN

Given : When the number is added to its reverse, the sum is 110

As the tens and units digit of the number are same, the reversed number is also : NN

⇒   NN + NN = 110

⇒   2NN = 110

⇒   NN = 55

Answer: The Number is 55

Answer:

x = 5     y = 2

Step-by-step explanation:

3x + 2(3x - 13) = 19

3x + 6x - 26 = 19

9x = 45

x = 5

y = 3(5) - 13

y = 15 - 13

y = 2

5x - 17 = 48

5x − 17 + 17 = 48 + 17

5x = 65

x = 13

180 - 48 = 132

y = 132
