HELP PLEASE 9TH GRADE MATH

Answer:

Each board is (4/25) meters long  = 0.16 meters long

Step-by-step explanation:

The board is 4/5 meters long, and he needs to cut 5 equal pieces, so we need to divide 4/5 of a meter in 5 parts.

This mathematically becomes: 4/5 divided by 5 which by the definition of division of rational numbers, is the same as :

4/5 times the reciprocal of 5 = (4/5) * (1/5) = (4/25) = 0.16 meters each board

Step-by-step explanation:

t has a value of 18.

In statistics, in addition to the mode and median, the mean is one of the measures of central tendency. Simply put, the mean is the average of the values in the given set. It indicates that values in a particular data set are distributed equally. The three most frequently employed measures of central tendency are the mean, median, and mode. The total values provided in a datasheet must be added, and the sum must be divided by the total number of values in order to determine the mean. When all the values are organized in ascending order, the Median is the median value of the given data. While the number in the list that is repeated a maximum of times is the mode.

As per the given data:

Mean of 18, 3, 18, t, 18 is 15

Mean = (Sum of all observations)/(Total number of observation)

Mean = (18 + 3 + 18 + t + 18)/5

15 = (18 + 3 + 18 + t + 18)/5

75 = 57 + t

t = 18

The value of t is 18.

Answer:

Step-by-step explanation:

g(x)=-2x+6

To find the y intercept set x = 0

g(0) = -2(0) +6

g(0) = 6

The y intercept is 6

(0,6)

To find the x intercept set y = 0

0 = -2(x) +6

Subtract 6 from each side

0-6 = -2x+6-6

-6 = -2x

Divide each side by -2

-6/-2 = -2x/-2

3 = x

The x intercept is 3

(3,0)

Answer:

x-int : 3

y-int : 6

Step-by-step explanation:

in order to find x intercept, you set the function equeal to 0

0= -2x + 6

then solve for x

-6 = -2x

3=x

To solve for the y intercept, you plug in 0 for x

y = -2(0) + 6

then solve  for y

y = 6

Answer:

[tex]\huge\boxed{\sqrt[9]{3}}[/tex]

Step-by-step explanation:

In order to convert the expression [tex](3^{\frac{2}{3}})^{\frac{1}{6}}[/tex] into a radical, we need to simplify it down first.

Using exponent rules, we know that [tex](a^b)^c[/tex] can be simplified to [tex]a^{b\cdot c}[/tex].

Therefore we can say that  [tex](3^{\frac{2}{3}})^{\frac{1}{6}}[/tex] is the same as [tex]3^{\frac{2}{3} \cdot \frac{1}{6}}[/tex].

[tex]\frac{2}{3} \cdot \frac{1}{6} = \frac{2}{18} = \frac{1}{9}[/tex]

So we have [tex]3^{\frac{1}{9}}[/tex].

When we have a number to a fraction power, it's the same thing as taking the denominator root of the base to the numerator power.

Basically:

If we have [tex]2^{\frac{3}{4}}[/tex]:

We'll take the denominator root (the denominator is 4) of the base (2):

[tex]\sqrt[4]{2}[/tex]

But inside the radical, we raise the base to the numerator (3) power.

[tex]\sqrt[4]{2^3}[/tex]

Same logic for  [tex]3^{\frac{1}{9}}[/tex]

[tex]\sqrt[9]{3^1}[/tex]

[tex]3^1[/tex] is the same as 3.

[tex]\sqrt[9]{3}[/tex]

Answer:

If the capital letter is symmetrical, only then would the letter be a vowel.

Step-by-step explanation:

Note, in logic a conditional statement or sentence refers to a statement that has a hypothesis (assumed condition), with a conclusion (or results).

In other words, the conditional statement is saying that a certain event would occur if the first condition is true.

For example,  saying: if today is Monday, only then would tomorrow be Tuesday.

Answer:

There are 200 trees per acre.

Step-by-step explanation:

47000 trees divided by 235 acres gets you 200 trees per acre.

When you go back and check your work, 200 trees per acre times 235 acres equals 47000 trees.

Answer:

a. 75.3% is the expected percentage and this value corresponds to 753 million dollars

b. 34.62% of items corresponds to 75% of this sales volume

Step-by-step explanation:

a. A =x(1-y)/(y-x)

X = 0.15, y = 0.50

A = 0.15(1-0.50)/(0.50-0.15)

= 0.15(0.5)/0.35

A = 0.2143

we have

x = 0.35

y = 0.35(1+0.2143)/(0.2143+0.35)

y = 0.425005/0.5643

y = 0.7531

y = 75.3%

75.3% is the expected percentage and this value corresponds to 753 million dollars

b. y = 0.75

find x

y = x(1+A)/(A+x)

x = yA/(1+A-y)

x = 0.75(0.2143)/1+0.2143-0.75)

x = 0.160725/0.4643

x = 0.3462

34.62% of items corresponds to 75% of this sales volume

Answer:

The probability of a random  unit is deemed faulty if it scores below 320.

P( X < 320 ) = 0.0505

Step-by-step explanation:

Explanation:-

Given mean of the Population 'μ' = 374

Variance of the Population σ² = 1090

Standard deviation of the  Population 'σ ' = √1090 = 33.01

Given 'X' be a random variable in normal distribution

[tex]Z = \frac{x -mean}{S.D} = \frac{320-374}{33.01} = -1.636[/tex]

Z = - 1.64

The probability of a random  unit is deemed faulty if it scores below 320.

P( X < 320 ) = P( Z < - 1.64 )

                   = 1- p(Z > 1.64)

                   = 1 - ( 0.5 + A(1.64)

                   = 0.5 - 0.4495

                  = 0.0505

The probability of a random  unit is deemed faulty if it scores below 320.

P( X < 320 ) = 0.0505

Answer: 0.0051

Step-by-step explanation:

Given the following :

Average Population weight (m) = 190

Population standard deviation (σ) = 35

Total weight of 25commuters (x) = 5200

Sample mean = 5200 /25 = 108

Sample standard deviation = standard error :

σ / √n = 35/√25 =

35/5 = 7

Zscore = (x - m) / standard error

Zscore = (208 - 190) / 7

Zscore = 18 / 7

= 2.57

P( Z > 2.57) = 1 - p(Z < 2.57)

P(z < 2.57) = 0.9949

1 - p(Z < 2.57) = 1 - 0.9949 = 0.0051

No
