Answer:

24%

Step-by-step explanation:

x-(11/100)x

89/100x

followed by

89/100x-13/100x

76/100x

so the total decrease is calculated as

x-76/100x

(24/100)x

i.e 24% decrease

alt ext: 1 and 8 and then 2 and 7. same side interior: 4 and 6 and 3 and 5

Answer:

The mean of X is 2 and the standard deviation is 1.3.

Step-by-step explanation:

For each dice rolled, there are only two possible outcomes. Either it lands on one, or it does not. The probability of a dice rolled landing on one is independent of any other dice. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

The standard deviation of the binomial distribution is:

[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]

Probability of rolling a 1.

Six sides, so:

[tex]p = \frac{1}{6} = 0.1667[/tex]

12 dices are rolled:

This means that [tex]n = 12[/tex]

Find the mean and standard deviation of X

[tex]E(X) = np = 12*0.1667 = 2[/tex]

[tex]\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{12*0.1667*0.8333} = 1.3[/tex]

The mean of X is 2 and the standard deviation is 1.3.

Respuesta:

113 N

Explicación paso a paso:

Las fuerzas ejercidas se dan como:

F1 = 30 N

F2 = 45 N

F3 = 38 N

A partir de los valores de las fuerzas ejercidas, podemos observar que todas las fuerzas están en la misma dirección; Dado que la fuerza total ejercida es un sol de las 3 fuerzas:

F1 + F2 + F3

(30N + 45N + 38N) = 113 N

Answer:

5.00

Step-by-step explanation:

1 quart is 32 ounces if you add 16+16=32

and 30 divided by 12 = 2.5

if one carton is 16 ounces and you add 2 cartons to make a quart which is 2.5+2.5=5.00

Answer:

D) 50, 60, 70

Step-by-step explanation:

The reason why it's D since a regular triangle equals up to 180 degrees in total and D is the only one that equals 180.

50+60+70= 180 degrees

Answer:

B. 315 meters

Step-by-step explanation:

The length of the longer side of the lot on drawing = 6.3 cm

Given a scale of 1cm : 50 m

Let the length of the longer side be represented as x.

Therefore, the actual length of the longer side will be calculated as follows:

1:50 = 6.3:x

1/50 = 6.3/x

Cross multiply

x*1 = 50*6.3

x = 315

Actual length of the longer side of the lot = 315 meters

Step-by-step explanation:

Iria made a scaled copy of the following triangle. She used a scale factor greater than 111.

What could be the length of the base of the scaled copy of the triangle?

Answer:

the answer is an obtuse triangle

The triangle in the image is an obtuse triangle.

In any triangle, the sum of the three angles is always 180 degrees.

Here, the sum of the two angles is 30 + 30 = 60 degrees.

Now, Adding the 120 degrees angle

= 60 + 120

= 180 degrees, which is consistent with the sum of angles in a triangle.

Now, let's consider the types of triangles:

1. Acute triangle: All three angles in an acute triangle are less than 90 degrees.

2. Right triangle: A right triangle has one angle that measures exactly 90 degrees.

3. Equilateral triangle: An equilateral triangle has all three angles equal to 60 degrees.

4. Obtuse triangle: An obtuse triangle has one angle that is greater than 90 degrees.

Thus, the triangle in the image is an obtuse triangle.

The circumference of a circle is 9.04 cm. Find the length of the diameter.

Let the radius of a circle be r cm.

We know the formula of circumference of a circle is 2πr.

ATQ ,

2πr = 9.04

2 × [tex] \frac{22}{7} [/tex] × r = 9.04

[tex] \frac{44}{7} [/tex] × r = 9.04

r = [tex] \frac{9.04 \: × \: 7}{44} [/tex]

r = [tex] \frac{63.28}{44} [/tex]

r = 1.438

Now, as we have to find the length of the diameter ,

So, we know, Diameter (d) = 2 × radius (r)

[tex] \therefore [/tex] d = 2r

Hence, d = 2 × 1.438 ( r = 1.438 )

d = 2.876

d = 2.88 ( approx )

Answer:

Vertical Angles

Step-by-step explanation:

Any opposite angles caused by two intersecting lines are vertical angles.

Any two adjacent angles caused by vertical lines or two angles that equal 180° are supplementary angles.

Two angles that make 90° in all are complementary angles.

Answer:Total number of students=6000 students

Step-by-step explanation:

Number  of female students =2640

Percentage of female students=44%

But

Percentage of female students x Total number of students =Number  of female students

Therefore

Total number of students=Number  of female students / Percentage of female students

Total number of students=2640/44% =6000 students
