Mathematics
1 answer:
ddd [48]4 years ago
8 0

Step-by-step explanation:

Total times the boxes were pulled and replaced = 22 + 8 = 30

Now

no of favourable cases, n (E) = 17

no of sample space, n(s) = 30

Now

Empirical probability of choosing a red block, P(e) = n(E) / n(S)

= 17/30

= 0.566

In the storage room of a certain bakery, the ratio of sugar to flour is 5 to 8, and the ratio of flour to baking soda is 10 to 1
olasank [31]

Answer:

1,500

Step-by-step explanation:

Ratio of Sugar to Flour: 5:8 -> 25:40

Ratio of Flour to Baking Soda: 10:1 -> 40:4

Sugar to Flour to Soda: 25x:40x:4x

\frac{40x}{(4x+60)} = \frac{8}{1} -> x = 60

Sugar = 25x = 1,500

Hope this helps :)

Simplify 4 n5 + 3.5 n5 + (-2.1 n5 ).
Alona [7]

Step-by-step explanation:    

<u>Step 1: Let's simplify step-by-step.</u>

4n^5 + 3.5n^5 - 2.1n^5

= 4n^5 + 3.5n^5 +  -2.1n^5

<u>Step 2: Combine Like Terms:</u>

= 4n^5 + 3.5n^5 + -2.1n^5

= (4n^5 + 3.5n^5 + -2.1n^5)

= 5.4n^5

 

Answer:    

=5.4n^5

 

Hope this helps.

A house appreciates (grows in value) about 6% each year. If the house is now worth 158,000, in about how many years will it be w
expeople1 [14]
200,000 = 158,000(1.06)^x
Divide both sides by 158,000
1.2658 = 1.06^x
Take the log of both sides and use the power rule to bring down the exponent (x) to the front.
log 1.2658 = x log 1.06
Divide both sides by log 1.06
log (1.2658)/log(1.06) = x
x = 4 years

CHECK
y = 158,000(1.06)^4
y = 199,471.36

The width of a rectangle is five less than twice the length. What is the minimum area of the rectangle?
Andrei [34K]
W=2L-5

-------------

A=L*W

=L(2L-5)

=2L²-5L

-------------

dA/dL=4L-5

When dA/dL=0,

4L-5=0

4L=5

L=5/4

----------------

When L=5/4

A=5/4*(2*(5/4)-5)

=5/4*(10/4-20/4)

=5/4*((-10)/4)

=5/4*(-5/2)

=-25/8

--------------------------------
