If 4 people out of 20 have a chance of getting a cold, what would be the risk of getting a cold?

Answer:

Step-by-step explanation:

-1<x<0

x<0

so x is negative.

Hence -x is positive.

and -1<x

or

x>-1

or

x+1>0

x+5=x+1+4>0+4

hence x+5 is positive.

x is negative .

∴x-2 is negative.

Answer:

3 3/4 cups of sugar per cup of salt

Step-by-step explanation:

To find the unit rate of salt to sugar in the recipe, we need to divide the number of cups of sugar by the number of cups of salt. In this case, the unit rate of salt to sugar is 1 1/4 cups of sugar divided by 1/3 of a cup of salt, which can be simplified to 3 3/4 cups of sugar per cup of salt.

Answer:

The unit rate of cups per teaspoon is 1 1/3

Step-by-step explanation:

-A recipe calls for 2 by 3 cup of sugar for every 1 by 2 teaspoon of vanilla.

Based on the above information, the calculation is as follows:

=(2/3)/(1/2)

=(2/3)/(1/2)

=(2/3)x(2/1)

=(2x2)/(3x1)

=(4/3)

= 1 1/3

The equation by using x represent the number of years and y represent the number of fish is y=900×(2)ˣ.

Given that,

James is keeping an eye on the fish population in the pond he created. He constructed a pond and added 900 fish to it. Every year, the fish population doubles.

We have to find the equation by using x represent the number of years and y represent the number of fish.

We know that,

We get

Number of fish at starting =900

Number of fish after 1 year =900×2=1800

Number of fish after 2 year =1800×2=3600=900×(2)²

Number of fish after 3 year =3600×2=7200=900×(2)³

So,

Here we can see that the number of fish are in Geometric progression (G.P) with a=900 and r=2

So,

Tₙ=arⁿ⁻¹

We get

y=900×(2)ˣ

Therefore, The equation by using x represent the number of years and y represent the number of fish is y=900×(2)ˣ.

f) No.

What is an expression?

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows: Expression: (Math Operator, Number/Variable, Math Operator)

Given that

the number of yellow tile in figure 1 is 8.

The number of yellow tile in figure 2 is 12.

The number of yellow tile in figure 3 is 16.

(a) The table is

Figure                     1             2            3  

Number of tiles      8            12          16

(b)

The number of tiles increase at a constant rate.

The rate is (12 - 8) = (16 - 12) = 4

The relation with the figure and number of tiles is

The number of tiles is = 4 + (the number of figure - 1)4

C)

Assume that y represents total number of tiles.

x = Number of figure

Rewrite "The number of tiles is = 4 + (the number of figure - 1)4" in term of x and y:

y = 8 +(x - 1)4

y = 8 + 4x -4

y = 4x + 4

d) Putting x = 24 in y = 4x + 4

y = 4×24 + 4

y = 96 + 4

y = 100

e)

Putting y = 176 in y = 4x + 4

176 = 4x + 4

Subtract 4 from both sides:

172 = 4x

Divide both sides by 4

x = 43

f)

Putting y = 54 in y = 4x + 4

54 = 4x + 4

Subtract 4 from both sides:

50 = 4x

Divide both sides by 4

x = 50/4

The value of x is not a whole number. Thus it is not possible that a figure has with 54 yellow tiles.

B) Units Of Activity Method       $3,048        $2,448

C) Declining Balance method   $5,200        $4,160

The depreciation expense is the periodic recognition of the cost for a long-term asset over its useful life.

The costs of long-term assets are spread over their estimated life through depreciation, depletion, or amortization.

The various depreciation methods include:

The cost of the delivery truck on January 1, 2022 = $26,000

Expected salvage value = $1,280

Depreciable amount = $24,720

Estimated useful life = 103,000 miles or 10 years

Depreciation Expenses:

Straight-line method = $2,472 annually ($24,720/10)

Units of activity method per mile = $0.24 ($24,720/103,000)

2022 = $3,048 (12,700 x $0.24)

2023 = $2,448 (10,200 x $0.24)

Declining-balance method rate = 20% (100/10 x 2)

[tex]n=45 \implies \frac{180(n-2)}{n}=\boxed{172^{\circ}}[/tex]

The degree measure of one angle of a 45-sided regular polygon is 172°.

When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.

Here, the polygon has 45 sides.

To find the measure of an interior angle of a regular polygon,

we make use of the formula for each angle = (n - 2) × 180 / n.

The formula calculated is only valid in cases of regular-sided polygons.

n =  45 substituting the value of n to the formula.

(n - 2) × 180 / n

= 180 ( 45-2) / 45

= 180 x 43 / 45

= 7740 / 45

= 172°

To solve this expression, we need to use the rules of order of operations, which dictate the order in which mathematical operations should be performed. The order of operations is typically abbreviated using the acronym PEMDAS, which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

Using the order of operations, we can solve the expression as follows:

64 - (-2)⁵ ÷ 2³ + (-1)³ · (0.5)²

= 64 - (-2)⁵ ÷ 8 + (-1)³ · 0.25

= 64 - (-32) ÷ 8 + (-1)³ · 0.25

= 64 + 32 + (-1)³ · 0.25

= 96 + (-1)³ · 0.25

= 96 + (-1) · 0.25

= 96 - 0.25

= 95.75

Therefore, the final result of the expression is 95.75

If roots are -5, -2, 0, 3, 6 factors are (x + 5), (x + 2), (x + 0), (x - 3), (x - 6).

∴The required polynomial is  (x + 5)(x + 2)(x + 0)(x - 3)(x - 6).
