Help??? The answer I put was an accident and I can’t take it away

Answer:

In simplified form, sin D is;

4/5

Step-by-step explanation:

The given figure and dimension parameters in the question are;

Triangle ΔDEF is a right triangle

The length of leg [tex]\overline{EF}[/tex] which is opposite side to the reference angle = 20

The length of segment [tex]\overline{ED}[/tex] which is the hypotenuse side of the right triangle ΔDEF = 25

The length of segment [tex]\overline{DF}[/tex] which is adjacent side to the reference angle = 15

By trigonometric ratios, we have;

[tex]sin\angle X = \dfrac{Opposite \ leg \ length}{Hypotenuse \ length}[/tex]

Therefore, we have;

[tex]sin\angle D = \dfrac{Opposite \ leg \ length}{Hypotenuse \ length} = \dfrac{20}{25} = \dfrac{4}{5}[/tex]

∴ In simplified form, sin(D) = 4/5.

The probability of A will be P(A) = 1/2. The probability of B will be P(B) = 1/2. The probability of A and B will be P(A and B) =  1/4

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

P(E) = Number of favorable outcomes / total number of outcomes

Event A: Rolling a number less than 4 on a number cube.

Event B: Flipping heads on a coin toss

We need to find the probability of A, the probability of B, and the probability of both A and B.

The probability of A will be

P(A) = 1/2

The probability of B will be

P(B) = 1/2

The probability of A and B will be

P(A and B) = 1/2 x 1/2

P(A and B) =  1/4

Answer:

C. y+3=−7/5(x+2)

Step-by-step explanation:

Line is passing through the points (-2, -3) and (-7, 4).

Slope of line = (-3 - 4)/[-2-(-7)]= (-7)/(-2+7) = - 7/5

Equation of line in the point-slope form is given as with point (-2, -3).

y - (-3) = - 7/5[x - (-2)]

y + 3 = - 7/5(x +2)

D is correct. you’re welcome.

Answer:

a) Line M

b)Line M

c)y=1/2x+2

Step-by-step explanation:

a) Line M has a greater y-intercept since its y-intercept is at (0,2) while Line N's y-intercept is at (0,1)

b) Line M has a greater slope since its line is steeper

c) Use the formula y=mx+b

Use the points ( 0,1) and (-4,-1)

m(slope)= y2-y1/x2-x1

m= (-1-1)/(-4-0)

m=-2/-4

m=1/2

substitute

(0)=1/2(-4)+b

2=b(y-intercept)

y=1/2x+2

Answer:

320 customers

Step-by-step explanation:

Well the chart given is a huge ratio since its a sample.

you would have this ratio

41:25:43:16

You can add them all up since then you would know how much people have actually be chosen for the survey.

You’d get 125. So 125 is the sample out of 2500 so we can divide to see how much of these “125” samples are in 2500.

You’d get 20.

So there are 20 “125” samples and we’re only focusing on drama which is 16 out of 125. 20*16 would be 320.

Answer:

Area = 137.6 units

Step-by-step explanation:

The equation for the area of a parallelogram is A = bh, where b = the base and h = the height. On this parallelogram, the base is 16 and the height is 8.6. Their product is 137.6.

Answer:

13

Step-by-step explanation:

Number of students that attended more than play = percentage of students that attended more than play x total number of students

5.5% x 232

0.055 x 232 = 12.76 students

to round off to the nearest whole number, look at the first number after the decimal, if it is less than 5, add zero to the units term, If it is equal or greater than 5, add 1 to the units term.

Since the first term is 7 which is greater than 5, 1 would be added to it.

This gives 13

Given:

The two triangles are similar by SSS.

To find:

The value of x.

Solution:

If two triangles are similar to each other by SSS, then the corresponding sides of the triangles are proportional.

It is given that [tex]\Delta ABC\sim \Delta DE F[/tex]. So,

[tex]\dfrac{AB}{DE}=\dfrac{BC}{EF}=\dfrac{AC}{DF}[/tex]

[tex]\dfrac{9}{6}=\dfrac{12}{8}=\dfrac{3(x-1)}{x+1}[/tex]

[tex]\dfrac{3}{2}=\dfrac{3}{2}=\dfrac{3x-3}{x+1}[/tex]

[tex]\dfrac{3}{2}=\dfrac{3x-3}{x+1}[/tex]

On cross multiplication, we get

[tex]3(x+1)=2(3x-3)[/tex]

[tex]3x+3=6x-6[/tex]

[tex]3x-6x=-3-6[/tex]

[tex]-3x=-9[/tex]

Divide both sides by -3.

[tex]x=3[/tex]

Therefore, the value of x is 3.

Answer:

3 magazines

Step-by-step explanation:

We will use ratios for this equation:

[tex]\frac{6}{18} =\frac{x}{9} \\\\18x=54\\x=3[/tex]

The number magazines you can buy with $9.00 is 3.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, at Nivea's Newsstand, 6 magazines cost $18.00.

Cost of 1 magazine is 18/6

=$3

Number of magazine with $9 is 9/3

= 3

Therefore, the number magazines you can buy with $9.00 is 3.

Given:

The height of 44 students (in centimeter) are presented in the given frequency distribution.

To find:

The median of the given data.

Solution:

The given intervals are inclusive first make the intervals exclusive by adding 0.5 in upper limit and by subtracting 0.5 from the lower limit.

The complete frequency distribution table is shown below:

Height              Frequency           L                            <cf

182 - 188                  1                  181.5 - 188.5            44

175 - 181                   3                 174.5 - 181.5             43

168 - 174                  6                 167.5 - 174.5            40

161 - 167                 15               160.5 - 167.5            34   Median class

154 - 160                 12                153.5 - 160.5           19

147 - 153                   4                146.5 - 153.5             7

140 - 146                   3                139.5 - 146.5             3

We have, [tex]n=44[/tex].

[tex]\dfrac{n}{2}=\dfrac{44}{2}[/tex]

[tex]\dfrac{n}{2}=22[/tex]

The 22th term is include in the class 160.5 - 167.5 because is cf is greater than 22 but the cf of o preceding class is less than 22. So, it is the median class is 160.5 - 167.5.

Formula for median:

[tex]Median=l+\dfrac{\dfrac{n}{2}-cf}{f}\times h[/tex]

Where, l is the lower limit of median class, cf is the cumulative frequency of preceding class, f is the frequency of median class and h is the size of the class.

Now, [tex]l=160.5,f=15,cf=19,h=7[/tex].

[tex]Median=160.5+\dfrac{22-19}{15}\times 7[/tex]

[tex]Median=160.5+\dfrac{3}{15}\times 7[/tex]

[tex]Median=160.5+1.4[/tex]

[tex]Median=161.9[/tex]

Therefore, the median of the given data table is 161.9.
