Hey there! The sentence is h + 240 = 18

Answer:

Answer:

48

Step-by-step explanation:

The ages are 18,28,38,48,58,68,78 I don't use 88 bacause the graph don't show any data so there is 88 years old

now lets find the mean

18+28+38+48+58+68+78= 336= 48

7 7

so the mean of the age is 48

Answer: $107,836.69 or about $107,837 (to the nearest dollar)

Step-by-step explanation:

Formula to the  accumulated amount received after investing principal amount (P) at rate of interest (r) compounded monthly for t months :

[tex]A=P(1+\dfrac{r}{12})^{t}[/tex]

As per given , A = $130,000

r= 7.5% = 0.075

t= 30 months

Now,

[tex]130000=P(1+\dfrac{0.075}{12})^{30}\\\\\Rightarrow 130000=P(1+0.00625)^{30}\\\\\Rightarrow 130000=P(1.00625)^{30}\\\\\Rightarrow 130000=P \times1.20552661036\\\\\Rightarrow\ P=\dfrac{130000}{1.2055266}=107,836.69[/tex]

Hence he need to invest $107,836.69 .

Answer:

  4(1000) +11(100) + 24(10,000) +11(1000) = 256,100

Step-by-step explanation:

Maybe you want to add 4000 +1100 to 24(10,000) +11,000.

1 thousand = 10 hundreds, so 4000 = 40 hundreds

  4000 +1100 = (40 +11) hundreds = 51 hundreds

__

1 ten-thousand = 10 thousands, so 24(10,000) = 240 thousands

  24(10,000) +11,000 = (240 +11) thousands = 251 thousands

__

So, we want to add 251,000 and 51 hundreds. The latter can be considered to be 5000 +100, so we have ...

  251,000 +5100 = 251,000 +5,100 = (251 +5) thousands + 1 hundred

  = 256,100

Answer:

The equations are:

[tex]T = 2Y[/tex] and [tex]T + 2Y = 15[/tex]

Step-by-step explanation:

Given

Represent bones eaten Today with T and yesterday with Y

Required

Write the equation

In the first statement, we have that:

[tex]T = 2Y[/tex]

Reading further; In the second statement

[tex]T + 2Y = 15[/tex]

Hence, the equations are:

[tex]T = 2Y[/tex] and [tex]T + 2Y = 15[/tex]

Solving further:

Substitute 2Y for  T in the second equation

[tex]2Y + 2Y = 15[/tex]

[tex]4Y = 15[/tex]

Divide both sides by 4

[tex]Y = \frac{15}{4}[/tex]

[tex]Y = 3.75[/tex]

Recall that

[tex]T = 2Y[/tex]

[tex]T= 2 * 3.75[/tex]

[tex]T= 7.5[/tex]

The answer is 1.

Answer:

two equal, real solutions

Step-by-step explanation:

The quickest way to determine this is to find the discriminant b^2 - 4ac.  If this determinant (D) is > 0, the quadratic has two different real roots; if + 0, the quadratic has two equal real roots, and if < 0, the quadratic has two imaginary or complex roots.

Here a = 5, b = 30 and c = 45.  The discriminant is

30^2 - 4(5)(45)  =  900 - 900 = 0

and so this quadratic has two equal, real solutions.

Answer:

1/4

Step-by-step explanation:

There are 8 possible outcomes

Multiples of 3 are

3,6  = 2 outcomes

P ( multiple of 3) = number of multiples of 3/ total

                            = 2/8

                             = 1/4

The probability of spinning a multiple of 3 The Spinner is 1-8 numbered will be  [tex]P= \dfrac{1}{4}[/tex]

Probability is the extent to which an event is likely to occur, measured by the ratio of the favourable cases to the whole number of cases possible.

There are 8 possible outcomes

Multiples of 3 are

Answer:

x = 17

KNM = 131

Step-by-step explanation:

(8x - 5) + (4x - 19) = 180

12x - 24 = 180

12x = 204

x = 17

Answer:

x = 17

Step-by-step explanation:

Opposite Angles must be the Same Value so In other words, 2(8x - 5) + 2(4x - 19) = 360.

2(8x - 5) + 2(4x - 19) = 360

24x - 48 = 360

24x = 408

x = 17

The number of six non conforming transducers at most =54/60=0.9

The number of fewer than six non conforming transducers =51/60=0.85

The number of at least six non conforming transducers at most =30/60=0.5

d) The center of the histogram is around 2 or 3 and it shows that there is some positive skewness in the data

∑                                    60                  

The number of six non conforming transducers at most

= 6+12+12+15+6+3= 54

The number of six non conforming transducers at most =54/60=0.9

The number of fewer than five non conforming transducers

= 6+12+12+15+6 = 51

The number of fewer than six non conforming transducers =51/60=0.85

The number of at least six non conforming transducers

2+1+3+3+6+15= 30

The number of at least six non conforming transducers at most =30/60=0.5

We plot the histogram by placing the percentages (or relative frequency *100) on the y –axis and the X on the x-axis.

The center of the histogram is given by the mean of the distribution which in this case is = ∑fx/∑f= 161/60= 2.683

So option d is the best answer

d) The center of the histogram is around 2 or 3 and it shows that there is some positive skewness in the data

Because at the center (between 2 and 3) the curve is increasing

Answer:

7th measurement = -26

Step-by-step explanation:

The sequence is 16, 9, 2, –5, ...,

First term( a)= 16

Second term=9

Common difference (d) = 9-16

Common difference= -7

The sequence is a arithmetic progression

For AP's ,the terms formula is

Term(n) = a + (n-1)d

Where n represent the term to be found

In this case,we Are looking for the 7th term , so n= 7

Term(7) = 16+ (7-1)-7

Term(7)= 16 +6(-7).

Term (7) = 16-42

Term(7) = -26

7th term =-26

Answer:

Section lines

Step-by-step explanation:

Sectioning is the process of cutting a surface by an imaginary plane, the view of the surface that is cut is shown in the section view.

Section lines are used to indicate where an imaginary cutting plane cuts a material. The imaginary cut is then represented using section lines which are usually thin, crosshatched.

Section lines shows the surface that have been cut by the cutting plane. There are different ways of sectioning such as full section, half section, off set section and so on

Answer:

-5

Step-by-step explanation:

think of it on a number line the number furthest to the left is always the smallest and the numbers to the right are bigger

Answer:

-5

Step-by-step explanation:

On a number line, there are negative and positive numbers.

The numbers -2, -4, and -5 are negative (see the little dash sign - ? that's negative).

2 is positive (you see no sign or a plus + before it).

The number line is a good way to learn negative and positive numbers.

go left, and the numbers go smaller

go right and they get bigger

-5 is the smallest since it is the most far left on the number line.

Step-by-step explanation:

The frequency and the time period is related by the formula as follows :

[tex]f=\dfrac{1}{T}[/tex]

Here, f is frequency and T is time period

Now, we need to solve T in terms of f.

Firstly, cross multiplying the above equation,

[tex]f\times T=1[/tex]

Now dividing both sides by T.

[tex]\dfrac{f\times T}{T}=\dfrac{1}{T}\\\\f=\dfrac{1}{T}[/tex]

Hence, this is the required solution.

Answer:

T= 1/f

Step-by-step explanation:

T= one OVER f

Answer:

(a) The value of P (X = 1, Y = 2) is 0.1583.

(b) The value of P (X + Y = 1) is 0.1055.

Step-by-step explanation:

It is provided that:

[tex]X\sim Bin(n=4,p=0.25)\\\\Y\sim Bin(n=4,p=0.50)[/tex]

The variables X and Y are independent random variables.

The probability mass function of a Binomial distribution is:

[tex]P(U=u)={n\choose u}(p)^{u}(1-p)^{n-u};\ u=0,1,2,3...[/tex]

(a)

Compute the value of P (X = 1, Y = 2) as follows:

[tex]P(X=1,Y=2)=[{n\choose x}(p_{x})^{x}(1-p_{x})^{n-x}]\times [{n\choose y}(p_{y})^{y}(1-p_{y})^{n-y}][/tex]; Independent

                           [tex]=[{4\choose 1}(0.25)^{1}(1-0.25)^{4-1}]\times [{4\choose 2}(0.50)^{2}(1-0.50)^{4-2}]\\\\=0.422\times 0.375\\\\=0.15825\\\\\approx 0.1583[/tex]

Thus, the value of P (X = 1, Y = 2) is 0.1583.

(b)

Compute the value of P (X + Y = 1) as follows:

[tex]P(X+Y=1)=P(X=0,Y=1)+P(X=1,Y=0)[/tex]

                       [tex]=\{[{4\choose 0}(0.25)^{0}(1-0.25)^{4-0}]\times [{4\choose 1}(0.50)^{1}(1-0.50)^{4-1}]\}\\+\{[{4\choose 1}(0.25)^{1}(1-0.25)^{4-1}]\times [{4\choose 0}(0.50)^{0}(1-0.50)^{4-0}]\}\\\\=(0.3164\times 0.25)+(0.422\times0.0625)\\\\=0.0791+0.0264\\\\=0.1055[/tex]

Thus, the value of P (X + Y = 1) is 0.1055.
