Suppose the cost of a speeding ticket where the speed is 65 miles per hour is:

A halloween assorted bag of candy contains 4 Snickers, 2 packages of M&M's, & 3 Butterfingers. What is the probability o

a_sh-v [17]

Answer:

2/27

Step-by-step explanation:

In the question we have:

4 snickers

2 packages of M&M's

3 Butterfingers.

Total number of candies in the Halloween bag = 9

Probability of selecting some M&M's and putting them back = 2/9

Probability of selecting a Butter finger = 3/9

Therefore, the probability of selecting some M&M's, putting them back, and then selecting a Butterfinger =

Probability of selecting some M&M's and putting them back × Probability of selecting a Butter finger

2/9 × 3/9

= 6/ 81

= 2/27

In what follows use any of the following tests: Regression, multiple regression, one-sided t-test, or two-sided t-test. All conc

Yakvenalex [24]

Answer:

Two sided t-test ( d )
0.245782 ( c )
Since P-value is too large we cannot conclude that the students’ weight are different for these two schools. ( c )
The test is inconclusive; thus we cannot claim that the average weights are different. ( b )

Step-by-step explanation:

1) Test performed is a Two sided test and this because we are trying to determine the mean difference between two groups irrespective of their direction

2) Determine the P-value ( we will use a data-data analysis approach on excel data sheet while assuming Unequal variances )

yes No

Mean 94.47059 89.76471

Variance 173.2647 95.19118

Observations 17 17

df 30

t Stat 1.184211

P(T<=t) one-tail 0.122814

t Critical one-tail 1.697261

P(T<=t) two-tail 0.245782

Hence The p-value = 0.245782

3) Since P-value is too large we cannot conclude that the students’ weight are different for these two schools.

4) The test is inconclusive; thus we cannot claim that the average weights are different.

Translate each of the following English statements into logical expressions. The domain of discourse is the set of all real numb

Scilla [17]

Answer:

A) З x,y : ( x/y < 1, y/x < 1 )

B) ∀ Y : ( Y > 0 = 1/Y > 0 )

C) з x,y : ( x+y = xy )

D) ∀ x,y : [ ( x>0 ) ∧( y > 0 ) = (( x/y > 0 ) ∧ ( y/x > 0 ))

E ) ∀ y : [ ( y > 0 ) ∧ ( y < 1) = ( 1 / y > 1 )

F) n ( ( з x ∀ y ( x <y ) )

G) ∀x (( x ≠ 0 ) = ( зy ( xy = 1 ) ))

H) ∀x ( (x≠0) = ( з! y (xy = 1))

Step-by-step explanation:

since the domain of discourse is a set of all real numbers the logical expressions of the English statements are expressed with respect to real number:

A) З x,y : ( x/y < 1, y/x < 1 )

B) ∀ Y : ( Y > 0 = 1/Y > 0 )

C) з x,y : ( x+y = xy )

D) ∀ x,y : [ ( x>0 ) ∧( y > 0 ) = (( x/y > 0 ) ∧ ( y/x > 0 ))

E ) ∀ y : [ ( y > 0 ) ∧ ( y < 1) = ( 1 / y > 1 )

F) n ( ( з x ∀ y ( x <y ) )

G) ∀x (( x ≠ 0 ) = ( зy ( xy = 1 ) ))

H) ∀x ( (x≠0) = ( з! y (xy = 1))

What two-digit number multiplied by itself has the product 2,025?

vivado [14]

Find the number with the same value when multiplied together get the result of 2 025.
=> to get the answer, find the square root of 2 025
=> √ 2 025 (the total number)
=> 45 (the number we are looking which is the square root of the given number.)
Thus, 45 is the number that will be multiplied together will result to 2 025.
Let’s check if our answer is correct
=> 45 x 45
=> 2 025
Therefore, our answer is correct

Use the properties of isosceles triangles to find m

RoseWind [281]

20° because isos has 2 equal sides. 70+70=140. You can see the triangle is dives in half. 180-140= 40. Then divide by 2 and get 20.
