Step-by-step explanation:

.04b is 2% of 2b because .04 multiplied by 100 is 4 then you divide by 2 which gets you 2.

.04/2=x/100

cross multiply and divide

it is 98% smaller than 2b.

.2b is 10% of 2b because .2 multiplied by 100 is 20 then you divide by 2 and get 10.

.2/2=x/100

it is 90% smaller than 2b.

.56b is 28% of 2b because .56 multiplied by 100 is 56 then divide by 2 and you get 28.

.56/2=x/100

it is 72% smaller than 2b.

1.8b is 90% of 2b because 1.8 multiplied by 100 is 180 then divide it by 2. you get 90.

1.8/2=x/100

it is 10% smaller than 2b.

2.5b is 125% of 2b because 2.5 multiplied by 100 Is 250 and 250 divided by 2 is 125.

2.5/2=x/100

it is 25% larger than 2b

3b is 150% of 2b because 3 multiplied by 100 is 300 and 300 divided by 2 is 150.

3/2=x/100

it is 50% larger than 2b

The area of the conference table in Mr. Nathan’s office must be no more than 175 ft2. If the length of the table is 18 ft more t

valentina_108 [34]

The answer is 0 < x ≤ 7

First, we know that width = x
Which means that length = x +18

So, the possible equation for the Table's area is

X (X + 18) ≤ 175

X^2 + 18x - 175 ≤ 0

Next, we need to calculate is by using complete square method
x^2 + 18x + 81 ≤ 175 + 81

(x + 9)^2 ≤ 256

|x + 9| ≤ sqrt(256)

|x + 9| ≤ +-16

-16 ≤ x + 9 ≤ 16

-16 - 9 ≤ x ≤ 16 - 9

-25 ≤ x ≤ 7

Since the width couldn't be negative, we can change -25 with 0,

so it become
 0 < x ≤ 7

What is the simplified form of StartRoot StartFraction 72 x Superscript 16 Baseline Over 50 x Superscript 36 Baseline EndFractio

aalyn [17]

Answer:

StartFraction 6 Over 5 x Superscript 10 Baseline EndFraction

Step-by-step explanation:

Apparently you want to simplify ...

$\sqrt{\dfrac{72x^{16}}{50x^{36}}}$

The applicable rules of exponents are ...

(a^b)(a^c) = a^(b+c)

1/a^b = a^-b

(a^b)^c = a^(bc)

So the expression simplifies as ...

$\sqrt{\dfrac{72x^{16}}{50x^{36}}}=\sqrt{\dfrac{36}{25x^{36-16}}}=\sqrt{\dfrac{36}{25x^{20}}}\\\\\sqrt{\left(\dfrac{6}{5x^{10}}\right)^2}=\boxed{\dfrac{6}{5x^{10}}}$

The value, V, of Kalani’s stock investments over a time period, x, can be determined using the equation V=750(0.80)^-x. What is

Katyanochek1 [597]

Answer:

The rate of this account corresponds to a increse of 25%.(Option 4)

Step-by-step explanation:

To find out the increase/decrease rate, first we need to re express the exponential term:

V=750*(0.80)^-x

By applying the respectives properties we can express the exponent of the equation as follows:

(0.80)^-x = 1/(0.8^x) = (1^x)/(0.8^x) = (1/0.8)^x = 1.25^x

Then the Kalani's stock investments can be written as:

V=750*1.25^x

Then the above equation can be expressed as:

V=750*(1+0.25)^x

Where 0.25 represents a increment rate of 25%

In a group of students, 30 played chess, 19 played volleyball, 25 played

saul85 [17]

Answer:

Explained below.

Step-by-step explanation:

Denote the events as follows:

C = chess

V = volleyball

B = basketball

The data provided is as follows:

n (C) = 30

n (V) = 19

n (B) = 25

n (C ∩ V) = 14

n (B ∩ V) = 8

n (B ∩ C) = 15

n (C ∩ V ∩ B) = 5

Consider the Venn diagram below.

The number of students who played only chess is marked in pink:

n (Only C) = 6

The number of students who played only volleyball is marked in blue:

n (Only V) = 2

The number of students who played only basketball is marked in orange:

n (Only B) = 7

The number of students who played all three is marked in grey:

n (C ∩ V ∩ B) = 5

A contractor purchases a shipment of 100 transistors. It is his policy to test 10 of these transistors and to keep the shipment

Serjik [45]

Answer:

Hence the probability of the at least 9 of 10 in working condition is 0.3630492

Step-by-step explanation:

Given:

total transistors=100

defective=20

To Find:

P(X≥9)=P(X=9)+P(X=10)

Solution:

There are 20 defective and 80 working transistors.

Probability of at least 9 of 10 should be working out 80 working transistors

is given by,

P(X≥9)=P(X=9)+P(X=10)

{80C9 gives set of working transistor and 20C1 gives 20 defective transistor and 100C10 is combination of shipment of 10 transistors}

P(X≥9)= ${80C9*20C(10-9)}/(100C10)+{80C10*20(10-10)}/(100C10)$

(Use the permutation and combination calculator)

P(X≥9)=(231900297200*20/17310309456440)

+(1646492110120/17310309456440)

P(X≥9)=0.267933+0.0951162

P(X≥9)=0.3630492
