Answer:

I believe that it is 7/26, but I think someone may still need to check my work.

Step-by-step explanation:

The first chance is 14/26, and the second is 13/25. If you incorporate those into each other, the closest option in my eyes is 7/26. However, I am not completely sure about this, so you should take this answer with a grain of salt.

Answer:

t=-4

Step-by-step explanation:

t+6=7/3.5

t+6=70/35 (I expanded 7/3.5 by multiplying both numerator and the denominator by 10)

t+6=2 (I divided 70 by 35 to get 2)

t=2-6

t=-4

Answer:

0.4246

Step-by-step explanation:

Given data:

mean ( u ) = 15 inches

std ( б )= 6 inches

sample size( n ) = 46

ux = mean sample length

Determine the probability that x within 0.5 inch of the claimed population mean

ux = u = 15

бx = б/ √ 46 =  6 /√ 46 = 6 / 6.78 = 0.88

Hence the   P( 14.5 < x < 15.5 )

= P ( [14.5 - 15 / 0.88 ] < z < (15.5 - 15) / 0.88) )

= P ( -0.5682 < z <  0.5682 )

= P ( z < 0.5682 ) - P ( z < -0.5682 )

= 0.7123 - 0.2877  ( from Z table )

= 0.4246

Answer:

[tex]AC=DB[/tex]

(corresponding parts of congruent triangles are equal)

Step-by-step explanation:

Consider triangles ACE and BDE.

As AB and CD bisect each other at point E,

[tex]AE=BE\\CE=DE[/tex]

As AB and CD intersect each other at point E and vertically opposite angles are equal,

∠AEC = ∠BED

So,

ΔAEC ≅ ΔBED       (Using SAS congruence criteria)

(According to SAS congruence criteria, if two sides and the included angle of one triangle are equal to the corresponding two sides and the included angle of another triangle then the two triangles are said to be congruent.)

Hence,

[tex]AC=DB[/tex]

(corresponding parts of congruent triangles are equal)

When segments AB and CD bisect each other at point E, the two triangles formed, [tex]\triangle AEC $ and $ \triangle BED[/tex], are congruent to each other SAS Congruence Theorem, therefore, AC = DB.

Recall:

Line segments AB bisecting line segment CD at point E will give us the triangles AEC and BED if we join A to C, and B to D.

Thus, the following information can be deduced from the image of both triangles shown in the attachment below:

[tex]EC \cong ED\\\\AE \cong BE[/tex] (congruent segments)

[tex]\angle AEC \cong \angle BED[/tex] (vertical angles)

From the above stated, [tex]\mathbf{\triangle AEC \cong \triangle BED}[/tex] by the SAS Congruence Theorem.

Since both triangles are congruent, all their corresponding sides would be congruent, therefore AC = DB.

In summary, when segments AB and CD bisect each other at point E, the two triangles formed, [tex]\triangle AEC $ and $ \triangle BED[/tex], are congruent to each other SAS Congruence Theorem, therefore, AC = DB.

Solution :

Equation for Malcom's family travels after t hours is d = 65 t

From the graph, equation for Theo's family travels after travels after t hours is

[tex]$d=\frac{225}{4.5}t$[/tex]

[tex]$d=50 t$[/tex]

For Malcom's family, speed [tex]$= \frac{d}{t}$[/tex] = 65 miles per hour

For Theo's family, speed [tex]$= \frac{d}{t}$[/tex] = 50 miles per hour

Malcom's family traveled faster than Theo's family by

        = (65-50) miles per hour

        = 15 miles per hour

Answer:

Step-by-step explanation:

6x= -78 you just solve it algabraicly

  6x= -78

    /6x  /6x

    x= -13

Answer:

x = 13

Step-by-step explanation:

Divide both sides of the equation by the same term

6x/6 =78/6

Simplify

Cancel terms that are in both the numerator and denominator

6x/6=78/6

x=78/6

Divide

x=78/6

x=13

Answer:

88.51

0.085343

67.39

Step-by-step explanation:

Given a normal distribution :

Mean (m) = 73

Standard deviation (s) = 11

Percentage A's = 7.93% = 0.0793

Minimum score needed to receive A :

Using the Z formula

Zscore corresponding to 0.0793 = 1.41

P(x ≥ x) :

Z = (x - m) / s

1.41 = (x - 73) / 11

11* 1.41 = x - 73

15.51 = x - 73

x = 15. 51 + 73

x = 88.51

B. Students who made 57.93 or lower on the exam failedthe course. What percent of students failed the course?

P(x ≤ 57.93)

Z = (x - m) / s

Z = (57.93 - 73) / 11

Z = - 15.07 / 11

Z = - 1.37

P( Z ≤ - 1.37) = 0.085343 ( Z probability calculator)

C.) If 69.5% of the students received grades of C or better, what is the minimum score of those who received C's?

Minimum score of those who received C

Zscore corresponding to 0.695 = -0.51 (Z probability calculator)

Z = (x - m) / s

-0.51 = (x - 73) / 11

11* - 0.51= x - 73

-5.61 = x - 73

x = - 5.61 + 73

x = 67.39

Answer:

861 : 615

Step-by-step explanation:

7 + 5 = 12

246 ÷ 12 = 123

7 × 123 = 861

5 × 123 = 615

861 -65 = 246

Place the midpoint of the protractor on the VERTEX of the angle.

Line up one side of the angle with the zero line of the protractor (where you see the number 0).

Read the degrees where the other side crosses the number scale.

The money will be worth 7412 at the end of the 12th year.

Compound interest is the interest that accrues on a loan or deposit on both the initial interests and principal.

Analysis:

To calculate the amount after 12 years we use the compound interest formula, A = P[tex](1 + \frac{r}{100} )^{n}[/tex]

where A = amount after a period of time, P = initial principal = 4500, r = rate = 4.25, n = number of years = 12.

 A = 4500[tex](1 + \frac{4.25}{100} )^{12}[/tex] = 7412

In conclusion, 7412 dollar will be realized at the end of the 12th year.
