Answer: 0.999548

Step-by-step explanation:

If the probability that a person will die next year is 425/1,000,000

The the probability of them not dying is:

(1,000,000-425)/1,000,000=999548/1,000,000

Next let’s move the decimal 6 spots to the left.

The answer would be 0.999548

For this case we have that a percentage equivalent to[tex]\frac {1} {8}[/tex]is given by:

Step-by-step explanation:

Y/1 = 2x + 5

Y = 2x + 5

Y = 2x + 5

When x = 1

Y = 2 ×1 +5

Y = 7

When x =0

Y = 2 × 0 + 5

Y = 5

When x = -2

X = 2 × -2 + 5

The graph for the coordinate points (0, 5), (1, 5.5), (2, 6), (3, 6.5) and (4, 7) is plotted below.

The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.

The given equation of a line is y=1/2x+5.

Substitute x=0, 1, 2, 3, 4, 5,....in a equation y=1/2x+5, we get

When x=0, y=5

When x=1, y=5.5

When x=2, y=6

When x=3, y=6.5

When x=4, y=7

So, the coordinate points are (0, 5), (1, 5.5), (2, 6), (3, 6.5) and (4, 7)

Therefore, the graph for the coordinate points (0, 5), (1, 5.5), (2, 6), (3, 6.5) and (4, 7) is plotted below.

Answer:

(f-g)(x) = x-3

Step-by-step explanation:

Given

f(x) = 3x-2

and

g(x) = 2x+1

We have to find (f-g)(x)

So,

(f-g)(x) = f(x)-g(x)

= 3x-2 - (2x+1)

= 3x-2-2x-1

=x-3

Hence,

(f-g)(x) = x-3

Answer:

( f - g ) ( x ) = x - 3

Step-by-step explanation:

We are to find [tex] ( f - g ) ( x ) [/tex] given that [tex] f ( x ) = 3 x - 2 [/tex] and [tex] g ( x ) = 2 x + 1 [/tex].

So basically we have to subtract the function g from function f.

[tex] ( f - g ) ( x ) = f(x) - g(x) [/tex]

Substituting the given functions in the above equation to get:

[tex] ( f - g ) ( x ) = (3x - 2) - (2 x + 1 ) [/tex]

[tex] ( f - g ) ( x ) = 3x - 2 - 2 x - 1  [/tex]

[tex] ( f - g ) ( x ) = 3x - 2 x - 2 - 1  [/tex]

[tex] ( f - g ) ( x ) = x - 3 [/tex]

Answer:

C. The domain is all real numbers, and the range is non-negative real numbers( [tex]y\ge0[/tex])

Step-by-step explanation:

The absolute value parent function is [tex]y=|x|[/tex]

The domain of a function refers to all values of x for which the function is defined.

The parent absolute value function is defined for all values of x.

Therefore the domain is all real numbers.

The range refers to the y-values for which x is defined.

The parent has a v-shape and its vertex is at the origin.

Therefore the least y-value is 0 and there is no maximum y-value.

The range is [tex]y\ge0[/tex]

Answer:

Osvoldo does not meet his goal

He had to have eaten at least 66 grams of whole grains to meet his goal.

Step-by-step explanation:

step 1

Find out the 30% of the grams of carbohydrates that Osvoldo ate today

Remember that

30%=30/100=0.30

so

0.30(220)=66 grams

step 2

Compare the 30% of the grams of carbohydrates that Osvoldo ate today with the 55 grams of whole grains

we know that

To Osvoldo meet his goal the 55 grams of whole grain must be greater than or equal to the 30% of the grams of carbohydrates that Osvoldo ate today

55 < 66

therefore

Osvoldo does not meet his goal

He had to have eaten at least 66 grams of whole grains to meet his goal.

Answer:

Left 4 units

Step-by-step explanation:

h(x) is a line with slope 2.  Let's say it has y-intercept b.  So:

h(x) = 2x + b

d(x) is h(x) shifted up 8 units.  So:

d(x) = h(x) + 8

d(x) = 2x + b + 8

We want to shift h(x) left or right to get d(x).  If we say that shift is a units to the right, then:

h(x−a) = d(x)

2(x−a) + b = 2x + b + 8

2x − 2a + b = 2x + b + 8

-2a = 8

a = -4

a is negative, so the shift is to the left.

h(x) should be shifted to the left 4 units.

The h(x) should be Left 4 units

Since

h(x) represent a line with slope 2.  

Let's assume it has y-intercept b.  

Therefore,

h(x) = 2x + b

d(x) represent h(x) shifted up 8 units.  

So,

d(x) = h(x) + 8

d(x) = 2x + b + 8

Now

h(x−a) = d(x)

2(x−a) + b = 2x + b + 8

2x − 2a + b = 2x + b + 8

-2a = 8

a = -4

Since a is negative, so the shift is to the left.

Answer:

Step-by-step explanation:

Note that both terms, 4x and -16, have something in common.

In math, this "something" is known as the greatest common factor (g.c.f.).

The g.c.f. of 4x and -16 is 4, so that's what we factor out.

First, we divide both 4x and -16 by 4.

We obtain.

x-4

Put parentheses around x-4

(x-4)

Now put 4 outside the parentheses

4(x-4)

Hope that this helped! Best wishes,

The factored form of the expression 4x - 16 is 4(x - 4).

To factor the expression 4x - 16, we can look for the greatest common factor (GCF) of the terms. In this case, both terms have a common factor of 4.

We can factor out the GCF of 4 from each term:

4x - 16 = 4(x - 4)

Therefore, the factored form of the expression 4x - 16 is 4(x - 4).

Step-by-step explanation:

rearrange the equations first

y=-3x-2---eq(1)

y=-3x+1-4

y=-3x-3---eq(2)

In first eq slope is -3x and y-intercept is -2

In second equation, the slope is -3x and y-intercept is -3

the slopes are the same in both equations but the y-intercepts are different

so the lines are parallel. The system is inconsistent

For this case we have the following system of equations:

[tex]3x = -2-y\\4 + y = -3x + 1[/tex]

By clearing "y" from both equations we have:

Equation 1:

[tex]3x + 2 = -y\\y = -3x-2[/tex]

Equation 2:

[tex]y = -3x + 1-4\\y = -3x-3[/tex]

It is observed that the slopes of both equations are equal. Recall that the equation of a line in the slope-intersection form is given by:

[tex]y = mx + b[/tex]

Where "m" is the slope.

If the slopes are equal, then the lines are parallel.

Answer:

Front section tickets: $40

Back section tickets: $25

Step-by-step explanation:

If x is the price of back section tickets, and x + 15 is the price of front section tickets, then:

275 (x + 15) + 325 x = 19125

275 x + 4125 + 325 x = 19125

600 x = 15000

x = 25

So back section tickets are $25, meaning front section tickets are $40.

Answer:

Step-by-step explanation:

We know: the angles measures in a triangle add up to 180°.

(look at the picture)

z + 50 + 60 = 180

z + 110 = 180    subtract 110 from both sides

z = 70°

x + 50 + 70 = 180

x + 120 = 180         subtract 120 from both sides

x = 60°

Angles x, y and z are on one side of a straight line. Therefore they add to 180°.

x + y + z = 180

60 + y + 70 = 180

y + 130 = 180         subtract 130 from both sides

y = 50°

Answer:

x = 60°, y = 50°

Step-by-step explanation:

We know: the angles measures in a triangle add up to 180°.

z + 50 + 60 = 180

z + 110 = 180    subtract 110 from both sides

z = 70°

x + 50 + 70 = 180

x + 120 = 180         subtract 120 from both sides

x = 60°

Angles x, y and z are on one side of a straight line. Therefore they add to 180°.

x + y + z = 180

60 + y + 70 = 180

y + 130 = 180         subtract 130 from both sides

y = 50°

Answer:

y  ≥ 14.
