Answer:

-35 meters

Step-by-step explanation:

He's below sea level, basically saying below 0= sea level.

Then it's basically saying -172+ 137 meters because the shark is going upwards 137 meters, which makes 137 positive. Dude, remember, up is positive and down is negative. So the answer to this problem would be -35 meters because of -172+137=-35. Hope this helped you.

Answer:it’s 5

Step-by-step explanation:

because it is

Quantity of flour needed to make 20 pancakes =

[tex] = 1 \frac{2}{3} \: [/tex]

[tex] = \frac{3 \times 1 + 2}{3} [/tex]

[tex] = \frac{5}{3} \: cups \: of \: flour[/tex]

Then , number of pancakes that can be made from 1 cup of floor :-

[tex]20 \div \frac{5}{3} [/tex]

[tex]20 \times \frac{3}{5} [/tex]

[tex] \frac{60}{5} [/tex]

[tex] = 12 \: pancakes[/tex] .

Therefore , 12 pancakes can be made from 1 cup of floor .

Number of pancakes that can be made with 1 cup of flour = 12 pancakes

Number of pancakes that can be made with 9 cups of flour :-

= 9 × 12

= 108 pancakes

Therefore , I can make 108 pancakes with 9 cups of flour .

Yes , I have enough flour to make 100 pancakes . I say this because :-

With one cup of flour I can make = 12 pancakes

With 9 cups of flour I can make =

= 9 × 12

= 108 pancakes

As I can make 108 pancakes with 9 cups of flour , I can conclude that I have enough flour to make 100 pancakes .

x = 33°

Then :-

m∠1 = 33° ( angle x and angle 1 are corresponding angles on a transversal )

m∠1 + m∠2 = 90° ( angle 1 and angle 2 are complementary angles )

33 + ∠2 = 90

∠2 = 90 - 33

m∠2 = 57°

m∠1 + m∠3 = 180° ( angle 1 and angle 3 are a linear pair )

33 + ∠3 = 180°

∠3 = 180 - 32

m∠3 = 147°

Answer:

80%

Step-by-step explanation:

To find what percent a part is of the whole, divide the part by the whole and multiply by 100%.

part = 48

whole = 60

percent = part/whole * 100%

percent = 48/60 * 100%

percent = 80%

Answer: 80%

Answer:

a) Entonces, habrá una población de [tex]1.329\times 10^{36}[/tex] bacterias a las dos horas.

b) La población de bacterias será de 33554432 en 25 minutos.

Step-by-step explanation:

a) De acuerdo con el enunciado, podemos apreciar una progresión geométrica, la cual está definida como:

[tex]n = n_{o}\cdot r^{t}[/tex] (Eq. 1)

Donde:

[tex]n_{o}[/tex] - Población inicial de bacterias, adimensional.

[tex]n[/tex] - Población actual de bacterias, adimensional.

[tex]r[/tex] - Tasa de reproducción de la población, adimensional.

[tex]t[/tex] - Tiempo, medido en minutos.

Si sabemos que [tex]n_{o} = 1[/tex], [tex]r = 2[/tex] and [tex]t = 120\,min[/tex], entonces la población actual de las bacterias:

[tex]n = 1\cdot 2^{120\,min}[/tex]

[tex]n = 1.329\times 10^{36}\,bacterias[/tex]

Entonces, habrá una población de [tex]1.329\times 10^{36}[/tex] bacterias a las dos horas.

b) Si empleamos (Eq. 1) y asumimos que [tex]n_{o} = 1[/tex], [tex]r = 2[/tex] and [tex]n = 33554432[/tex], entonces despejamos [tex]t[/tex] de la fórmula resultante:

[tex]1\cdot 2^{t} = 33554432[/tex]

[tex]2^{t} = 33554432[/tex]

[tex]\log_{2} 2^{t} = \log_{2} 33554432[/tex]

[tex]t = \log_{2} 33554432[/tex]

[tex]t = 25\,min[/tex]

La población de bacterias será de 33554432 en 25 minutos.

Answer:

0.25q

Step-by-step explanation:

A cash register is a machine used in small business that sums, display and records the total amount made by each sale. A cash register also has a drawer which is used to store money.

A quarter is a coin in the United States which is 25 cents.

Converting 25 cents to dollars:

100 cents = $1

25 cents = 25 cents × $1 / 100 cent = $0.25

The total amount of money registered = number of quarters × $0.25

The total amount of money registered = q × $0.25 = 0.25q

Answer:

8212.67

Step-by-step explanation:

From the data given in the question;

Amount = 15000

Principal = ?

rate = 8.25%

time = 10 years

From;

A =P(1 + r)^n

15000 = P(1 + 0.0825)^10

P= 15000/2.21

P= 6787.33

but

Interest = Amount - Principal

Interest = 15000 - 6787.33

interest = 8212.67

Answer:

i

Step-by-step explanation:

Given the complex value i^25, we are to write in terms of i. In complex number:

i² = -1

i^25 =( i²)¹² × i

= (-1)¹² × i

Note that -1 to a negative number will give a positive number hence (-1)¹² = 1

(-1)¹² × i = 1×i

= i

Hence i^25 = i

Answer:

The probability is [tex]P(S | (O ,U)' ) = 0.05[/tex]

Step-by-step explanation:

From the question we are told that

  The probability of each company to be chosen is

            Supplier               G           J           S           O             U

            Probability           0.15     0.04     0.01       0.55       0.25

Generally the probability that company  G , J  ,  S are chosen is  

       [tex]P(G , J , S ) = 0.15 + 0.04 + 0.01[/tex]

=>    [tex]P(G , J , S ) = 0.20[/tex]

Generally the probability that company  O, U are chosen is  

      [tex]P(O, U ) = 0.55+ 0.25[/tex]

=>   [tex]P(O, U ) = 0.80[/tex]

Generally  the probability that supplier S will be chosen given that suppliers O and U are both ultimately not chosen is mathematically represented as

     [tex]P(S | (O ,U)' ) = \frac{ P(S \ n \ (O , U)' )}{ P((O, U)')}[/tex]

    [tex]P((O, U)' = 1 - P(O , U)[/tex]    

    [tex]P((O, U)' = 1 - 0.8[/tex]    

   [tex]P((O, U)' =0.2[/tex]

And  

     [tex]P(S \ n \ (O , U)' ) = P(S) = 0.01[/tex]

=>   [tex]P(S | (O ,U)' ) = \frac{ 0.01 }{ 0.2}[/tex]

=>   [tex]P(S | (O ,U)' ) = 0.05[/tex]

Answer:

d. The histogram would be approximately bell-shaped, and the normal quantile plot would have data points have follow a straight-line pattern.

Step-by-step explanation:

Since the variable is normally distributed, the histogram of women's height should be approximately bell shaped (if the data was obtained form a random sample).

Again, the variable is normally distributed, therefore, the quantile plot should follow a straight line pattern (a diagonal line to be more precise).

Step-by-step explanation:

Perimeter of a rectangle = 2(L+W)

L is the length of the rectangle:

W is the width of the rectangle.

Given

Perimeter = 214feet

If the length is 41 ft longer than the width, then L = 41+W

Substitute L = 41+W into the formula:

P = 2(L+W)

214 = 2(41+W+W)

214 = 2(41+2W)

214 = 82+4W

4W = 214-82

4W = 132

W = 132/4

W = 33 feet

Since L = 41+W

L = 41+33

L = 74 feet

Hence the dimension of the field is 74ft by 33ft

The width of the playing field is 33feet

Answer:

x<10

Step-by-step explanation:

i think this is the answer

x<10 is the solution of the inequality  2x-8 <12

A relationship between two expressions or values that are not equal to each other is called 'inequality.

The given inequality is 2x-8<12

Two times of x minus eight less than twelve

x is the variable

We have to find the solution of the inequality

2x<20

Divide both sides by 2

x<10

Hence, x<10 is the solution of the inequality  2x-8 <12

Answer:

The number of standard deviation above the mean is  [tex]  z_o   = 1.4607 [/tex]

Step-by-step explanation:

From the question we are told that

   The mean weight of  ears of  corn from each farm is  [tex]\mu=1.26[/tex]

   The standard deviation of ears of corn from Iowa is [tex]\sigma_1[/tex]

   The standard deviation of ears of corn from Ohio is

       [tex] \sigma_2= 0.01 + \sigma_1 [/tex]

  The weight of a random selected ear of corn from Iowa is  x =  1.39 pound

  The standardized score is  z =1.645

   The weight of a random selected ear of corn from Ohio is  [tex]x_1 =  1.39\ pound[/tex]

Generally the standardized score of weight of corn from Iowa is mathematically  represented as

        [tex]z  =  \frac{ 1.39 -  1.26 }{\sigma_1 }[/tex]

=>     [tex] 1.645 =  \frac{ 1.39 -  1.26 }{\sigma_1 }[/tex]  

=>      [tex]  \sigma_1 =  \frac{ 1.39 -  1.26 }{ 1.64 5}[/tex]  

=>      [tex]  \sigma_1  =   0.0790 [/tex]  

Generally the standardized score of weight of corn from Ohio is mathematically  represented as

         [tex]z_o  =  \frac{ 1.39 -  1.26 }{\sigma_2 }[/tex]

=>     [tex] z_o=  \frac{ 1.39 -  1.26 }{0.01 + \sigma_1 }[/tex]  

=>      [tex]  z_o =  \frac{ 1.39 -  1.26 }{  0.089}[/tex]  

=>      [tex]  z_o   = 1.4607 [/tex]

Because the value is positive it means that this value represent the number of standard deviation above the mean.

Using the normal distribution, it is found that the weight with respect to the Ohio distribution is 1.46 standard deviations from the mean.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

For the Iowa farm:

Then, the standard deviation can be found as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.645 = \frac{1.39 - 1.26}{\sigma}[/tex]

[tex]1.645\sigma = 0.13[/tex]

[tex]\sigma = \frac{0.13}{1.645}[/tex]

[tex]\sigma = 0.079[/tex]

In Ohio:

Hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{1.39 - 1.26}{0.089}[/tex]

[tex]Z = 1.46[/tex]

The weight with respect to the Ohio distribution is 1.46 standard deviations from the mean.
