Need help with question​

Answer: 0

Step-by-step explanation:

Given that :

Mean score on test = 5

Standard deviation on test = 2

Distribution = normal

The mean value when Converted to a z - distribution :

Zscore = (x - mean) / standard deviation.

Hence z score for the mean score will be :

X = mean score

Zscore = ( 5 - 5) / 2

Zscore = 0 / 2

Zscore = 0

Mean value when Converted to a z distribution will be 0

Step-by-step explanation:

The dime which is worth 0.10 U.S. dollar, is a ten-cent coin, one-tenth of a United States dollar

the value is 0.1

Now in rounding up of numbers the dime is located one decimal place away i.e 0.5 in the number given in the problem statement

to round up to the nearest dime we have to consider the next number to the dime if this number is greater than 5 we will round up if it is less than five we can not perform any rounding up operation

hence the greatest amount of money is

since the number next to 5 is 9 and 9 is greater than 5 we will round up from 5 to 6

This makes 108.59  the greatest amount of money that rounds to​ $108.60

Answer:

0.4

Step-by-step explanation:

Do 2/4 divided by 6.

The measure of the angle ∠XWZ will be half of the measure of the angle ∠XWY.

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.

The measure of the angle ∠XWY is twice the measure of the angle ∠XWZ.

∠XWY = 2 ∠XWZ

Simplify the equation, then we have

∠XWZ = ∠XWY / 2

Then the measure of the angle ∠XWZ will be half of the measure of the angle ∠XWY.

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{3 \frac{5}{12}}}}}} [/tex]

Step-by-step explanation:

[tex] \star{ \sf{ \: \: \frac{5}{3} + \frac{7}{4}}} [/tex]

Convert the given fractions into like fractions.

To do so, Take the L.C.M ( Least Common Multiple ) of 3 and 4.

To find out the L.C.M of given numbers,

First of all, find the prime factors of each numbers.

3 = 3 × 1

4 = 2 × 2 × 1

Take out the common prime factor i.e 1

Also take out the other remaining prime factors i.e 2 , 2 and 3

Now, multiply those all prime factors and obtain L.C.M

= 1 × 2 × 2 × 3 = 12

L.C.M of 3 and 4 = 12

[tex] \dashrightarrow{ \sf{ \frac{5 \times 4 + 7 \times 3}{12}}} [/tex]

[tex] \dashrightarrow{ \sf{ \frac{20 + 21}{12}}} [/tex]

Add the numbers : 20 and 21

[tex] \dashrightarrow{ \sf{ \frac{41}{12}}} [/tex]

Convert the improper fraction into mixed fraction

[tex] \dashrightarrow{ \boxed{\sf{3 \frac{5}{12} }}}[/tex]

Remember : While performing the addition or subtraction of unlike fractions, you have to express the given fractions into equivalent fractions of common denominator and add or subtract as we do with like fractions. Thus , obtained fractions should be reduced into lowest terms if there are any common on numerator and denominator. But in case of improper fraction, it needs to be deduced on mixed fraction.

Step-by-step explanation:

As x → + ∞ , y → + ∞ , as x → - ∞, y → - ∞

This means as x increases to the right, y increases up and as x increases to the left, y is increasing downwards

Answer:

True

Step-by-step explanation:

Given

[tex]Location: (a,0)[/tex]

Required

Does the location represent the x intercept?

The general point form of a function is (x,y)

When y = 0;

This represents that the function crosses the y axis.

And whenever the function crosses the y axis, we have the x intercept of the function

Hence, the statement is true

Answer:

1 bushel = 32 quarts

Step-by-step explanation:

It is given that,

No. of pecks in a bushel = 4

No of quarts in a peck = 8

We need to find the relationship between number of bushels, b, and the number of quarts, q.

No. of quarts in 4 pecks = 4×8 = 32 quarts

It would mean that there are 32 quarts in 1 bushel.

Hence, 1 bushel = 32 quarts

Answer:

x = - 4    y = - 4

Step-by-step explanation:

x+y= - 8

-9x-6y=60

First, solve for x in the first equation:

x+y = - 8       Subtract y from both sides

x + y - y = -8 - y    y cancels on the left

x = - 8 - y

Now plug in what you found for x into the 2nd equation and solve for y.

- 9x - 6y = 60

-9(- 8 - y) - 6y = 60   Multiply out

72 + 9y - 6y = 60

72 + 3y = 60  Subtract 72 from both sides

72 - 72 + 3y = 60 - 72    72 cancels on the left

3y = - 12     Divie both sides by 3

3y/3 = -12/3     3 cancels on the left because 3/3 = 1

y = -4

Now plug your answer for y back into the first equation to get x.

x + y = -8

x + (-4) = - 8  Add 4 to each side

x - 4 + 4 = - 8 + 4   4 cancels on the left

x = -4

x = - 4 and y = - 4

Answer:

The probability that a worker was taught by method A given that he learned the skill successfully is 0.72.

Step-by-step explanation:

(1)

The information provided is:

A = if method A is used

B = if method B is used

S = successfully learning the skill

P (A) = 0.75

P (B) = 0.25

P (S|A) = 0.80

P (S|B) = 0.95

Compute the probability that a worker was taught by method A given that he learned the skill successfully as follows:

[tex]P(A|S)=\frac{P(S|A)P(A)}{P(S|A)P(A)+P(S|B)P(B)}[/tex]

            [tex]=\frac{0.80\times 0.75}{0.80\times 0.75+0.95\times 0.25}\\\\=\frac{0.60}{0.60+0.2375}\\\\=\frac{0.60}{0.8375}\\\\=0.716418\\\\\approx 0.72[/tex]

Thus, the probability that a worker was taught by method A given that he learned the skill successfully is 0.72.
