In the number 789.466 the digit in the hundredths place is______ the value of the digit in the thousandths place?​

Answers

Answer:

hundredths --> 6

thousandths value --> 0.006

Step-by-step explanation:

hundredths is the value two places to the right of the decimal point, which is currently 6.

The value of the digit in the thousandths place, which is 3 places to the right of the decimal place, is 6, but the value of the 6 is actually 0.006, because it is in the thousandths place, just like 700 would be the value of the digit in the hundreds place.

PRACTICE ANOTHER Is 4a a factor of 2a · 38b? (Assume that a and b represent integers.) Yes, because 4 is a multiple of 38. Yes, because 2a · 38b = 4a · 19b where 4a and 19b are integers because a and b are integers and products of integers are integers. Yes, because 4a is a divisor of 38b. No, because 38 is not a divisor of 4. No, because 2a · 38b = 4a · 19b where 4a and 19b are not necessarily integers because products of integers are not always integers.

The equations of sides of a triangle are 2x-3y+5=0, 2x+y=7 and 2x+5y=3. Find the coordinates of the vertices.

Answers

Answer:

Vertices A B y C

A ( 2 , 3 )    B ( -1 , 1 )  C ( 3, 1 )

Step-by-step explanation:

We have to solve a two-equation system, by pair of equations as follows

equation (1)   2x - 3y + 5 = 0

equation (2)  2x + y -7    = 0

Solving this system we find let´s say vertex A

0x - 4y +12 = 0      y = 3

Then x ?

2x - 3y + 5 = 0

2x - 9 + 5 = 0     ⇒ 2x = 4     x = 2

Then vertex A ( 2 , 3 )

From equation (1) and (3)

2x - 3y + 5 = 0

2x + 5y - 3 = 0

Agan subtracting (1) - (2)

0x -8y + 8 = 0

y = 1    and      

2x + 5y = 3

2x + 5 = 3

2x = -2

x = -1

Vertex B ( -1 , 1 )

Finally from equation (2) and (3) we get the third vertex C

2x + y - 7 = 0

2x + 5y - 3 = 0

0x -4y -4 = 0

y = 1

2x + y = 7

2x + 1 = 7

2x = 6

x = 3

C ( 3 , 1 )

The population of weights of a particular fruit is normally distributed, with a mean of 464 grams and a standard deviation of 6 grams. If 27 fruits are picked at random, then 2% of the time, their mean weight will be greater than how many grams?

Answers

Answer:

If 27 fruits are picked at random, then 2% of the time, their mean weight will be greater than 466.37 grams

Step-by-step explanation:

Mean = [tex]\mu = 464[/tex]

Standard deviation =[tex]\sigma = 6[/tex]

We are supposed to find If 27 fruits are picked at random, then 2% of the time, their mean weight will be greater than how many grams i.e.P(X>x)=0.02

The mean weight is in the highest 2%, you want to go to a z-table and find the z-score that where the area to the left of the curve is closest to 0.98.

n = 27

Refer the z -table

P(Z>x)=2.06

[tex]\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}=2.06\\\frac{x-464}{\frac{6}{\sqrt{27}}}=2.06\\x-464=2.06 \times \frac{6}{\sqrt{27}}\\x=(2.06 \times \frac{6}{\sqrt{27}})+464\\x=466.37[/tex]

So, If 27 fruits are picked at random, then 2% of the time, their mean weight will be greater than 466.37 grams

The equation in the given question is-

[tex](x+3)(x) < =50\\\\x^{2} +3x-50 < =0\\\\x^{2} +3x-50=0\\\\x = \frac{-3 +\sqrt{9+4*50} }{2} ,\frac{-3 -\sqrt{9+4*50} }{2}\\\\x = \frac{-3 +\sqrt{209} }{2} ,\frac{-3 -\sqrt{209} }{2}\\\\\\x = -8.728, 5.728\\\\x =[-8.728, 5.728][/tex]

Triangle BIG is similar to triangle MOP . Find v .

Answers

Answer:

63:42

so this is

3:2

[tex] \frac{33}{3} = \frac{v}{2} [/tex]

[tex]v = \frac{2 \times 33}{3} = \frac{66}{3} = 22[/tex]

v=22

The value of v should be considered as the 22 when the Triangle BIG is similar to triangle MOP.

Calculation of the value of v:

Since as per both the figures we can write the ratio like  63:42 so it can be like 3:2

So the calculation could be done below

[tex]33 \div 3 = v \div 2\\\\v = 2 \times 33 \div 3\\\\= 66 \div 3[/tex]

= 22

Hence, The value of v should be considered as the 22 when the Triangle BIG is similar to triangle MOP.

If f is decreasing on [a,b] then the minimum value of f(x) on [a,b] is f(a)?

Answer:

False

Step-by-step explanation:

Given

[a,b]

Where f(x) is decreasing

Required

Is the minimum f(a)?

This statement is false and it is proved using the following illustration

Take f(x) to be

[tex]f(x) = -2x[/tex]

The above represents a decreasing function because:

f(x) decreases as x increases

Having said that:

Assume [a,b] is:

[tex][a,b] = [2,5][/tex]

Substitute the value of a i.e. 2 for x in f(x)

[tex]f(2) = -2 * 2[/tex]

[tex]f(2) = -4[/tex]

Substitute the value of b i.e. 5 for x in f(x)

[tex]f(5) = -2 * 5[/tex]

[tex]f(5) = -10[/tex]

Notice that f(b) < f(a) i.e. -10 is less than -4

Hence:

f(x) is minimum at f(b)

Conclusively, the statement is false
