Answer:

The original number was -8

Step-by-step explanation:

You can find this out because -8 divided by 2 is -4 and then plus 10 would become 6

Answer:

-8

Step-by-step explanation:

We know that Sara has a number by which she divides by 2, added 10 and ended up with 6. We are then asked to find the original number she had in mind.

To solve, we need to go backwards, starting with the original number, and applying all the steps she did but with the opposite operation.

6 is her ended number, we know before she added 10, so subtract 10 from 6:

[tex]6-10=-4[/tex]

Now we know that she divided by 2, therefore multiply -4 by 2:

[tex]-4*2=-8[/tex]

-8 was Sara's first number.

Answer:

16.875 spiders

Step-by-step explanation:

Given

Let

[tex]B = Beetles[/tex]

[tex]C = Birds[/tex]

[tex]S = Spiders[/tex]

So, we have:

[tex]B = C = S[/tex] --- equal amounts

[tex]6B + 2C + 8S = 270[/tex] --- the legs

Required

The number of spider

Since she has an equal amount of B, C and S;

The expression can be written as:

[tex]6B + 2C + 8S = 270[/tex]

[tex]6S + 2S + 8S = 270[/tex]

[tex]16S = 270[/tex]

Solve for S

[tex]S = \frac{270}{16}[/tex]

[tex]S = 16.875[/tex]

The result of the solution does not represent real life situation because it it is not possible to have a fraction number of spider

Answer:

KL = 5.3

Step-by-step explanation:

Base on proportionality theorem, we have the following equation showing the relationship between the segments:

4/6 = KL/8

Cross multiply

6*KL = 8*4

6*KL = 32

DIvide both sides by 6

KL = 32/6

KL ≈ 5.3

If the tangent is drawn from the outside of the circle. Then the length of the tangents will be same. Then the perimeter is 30 cm.

Let the triangle be ABC. Then the perimeter of the triangle will be

Perimeter = AB + BC + CA

We know that if the tangent is drawn from the outside of the circle. Then the length of the tangents will be same.

Then the completed diagram is given below.

Answer:

12

It would be easier to explain if the triangle and the parallelogram have their points named.

Some first hints: The area of a tri

angle equals to 1/2 of height times length of corresponding base side. The area of a parallelogram equals to height times the corresponding base side. in addition, in a parallelogram, two opposing side have the exact same length.

Since then, we can write the area of the triangle as 1/2× h× 18= 9×h

we can write the area of the parallelogram as : 18×h

Since then, we can write the area of the compound as 9×h + 18×h= 27h.

Voila. I gues you can figure out the rest. Please ask more if you have trouble with this

Answer:

<a=138°

<b=42°

<c=138°

<d=138°

<e=42°

<f=42°

Step-by-step explanation:

<a is supplementary with the 42° angle:

<a=180°-42°=138°

<b and the 42° are vertical angles, so:

<b=42°

<c and <a are also vertical angles so:

<c=<a=138°

<d and <a are corresponding angles, so:

<d=<a=138°

<e and <b are corresponding angles, so:

<e=<b=42°

<f and the 42° angle are corresponding angles, so:

<f=42°

Answer:

1 / 64

Step-by-step explanation:

The probability of a multi-stage events that are independent is the product of all of them. Probability is basically the desirable outcomes over the total outcomes. When rolling a die, there are 6 different numbers you can roll, meaning six different outcomes. There are 3 outcomes where you can roll an even number: 2, 4, and 6. And it's the same with odd numbers: 1, 3, and 5. So the probability of rolling an even number is 3 / 6 or 1 / 2 and the probability of an odd number is the same, 1 / 2. Now, since the probabilities are the same at each stage, we can multiply 1 / 2 to itself 6 times or (1/2)^6 which evaluates to 1 / 64.

S10= -341

Step-by-step explanation:

1,-2,4,-8,16,.......

Sum of first 10 terms of geometric sequence

Sn=a(r^n-1)/r-1

where, a= first term

n= number of terms

r=common ratio

common ratio (r)= second term/first term

r=-2/1

r=-2

a=first term

a=1

n= number of terms

n=10

S10=1[(-2)^10-1]/-2-1

S10=(1024-1)/-3

S10=1023/-3

S10= -341

therefore, the sum of the first 10 terms is -342

Answer:

20/9

Step-by-step explanation:

2/(9/10)=(2/1)(10/9)=20/9

Answer:

The theoretical probability that the first number is even and the second number is odd is [tex]\frac{1}{4}[/tex].

Step-by-step explanation:

Since each dice has six sides, and there are two die, the total amount of different outcomes are [tex]6^2[/tex] or 36. The probability of getting an even number on the first roll is [tex]\frac{3}{6}[/tex] or [tex]\frac{1}{2}[/tex], and the probability of getting an odd number on the second roll is also [tex]\frac{3}{6}[/tex] or [tex]\frac{1}{2}[/tex], so the probability of getting an even number on the first roll and an odd number on the second roll is [tex]\frac{1}{2} * \frac{1}{2} = \frac{1}{4}[/tex].

The standard deviation of the distribution is 1.08.

Option B is the correct answer.

The standard deviation measures how spread out the data is from the mean, and it is a measure of the average distance of the data points from the mean.

We have,

To find the standard deviation of the distribution, we first need to calculate the expected value (mean) of X.

The expected value of X is:

E(X) = (4)(0.4) + (3)(0.32) + (2)(0.17) + (1)(0.08) + (0)(0.03)

= 1.6 + 0.96 + 0.34 + 0.08 + 0

= 2.98

Next, we need to calculate the variance of X:

Var(X) = (4 - 2.98)²(0.4) + (3 - 2.98)²(0.32)

+ (2 - 2.98)²(0.17) + (1 - 2.98)²(0.08) + (0 - 2.98)²(0.03)

= 0.64(0.4) + 0.0004(0.32) + 0.7921(0.17) + 5.4084(0.08) + 8.6404(0.03)

= 0.256 + 0.000128 + 0.134257 + 0.432672 + 0.259212

= 1.082

The standard deviation of X is the square root of the variance:

So,

SD(X) = √(Var(X))

= √(1.082)

= 1.04 (approximately)

Thus,

The standard deviation of the distribution is 1.08.

Step-by-step explanation:

the equation :

Hn = 7n + 3

where :

Hn : the height of trees at year to-n

n : year to-n (n = 1,2,3,...)

so, the rate of change : increasing 7 feet per year.

The rate of change of the average height and feet of the trees on the farm with respect to the number of years will be 7.

A slope is a tangent or angle at a point and a slope is the intensity of inclination of any geometrical lines.

Slope = Tanx where x will be the angle from the positive x-axis at that point.

The slope could be positive or negative.

The slope is also calculated by differentiation for example slope of y = sinx will be y' = cosx.

The rate of change also refers to the slope.

The slope associated with two points (x₁, y₁) and (x₂, y₂) is given by

Slope = (y₂ - y₁)/(x₂ - x₁).

Taking two points (1,10) and (3,24)

Slope associated with these;

(24-10)/(3-1) = 7

Hence "The rate of change of the average height and feet of the trees on the farm with respect to the number of years will be 7".

Answer:

0.2052 = 20.52% probability that their hair was done by Chris

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

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

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Customer not satisfied

Event B: Hair done by Chris.

Probability of a customer not being satisfied.

5% of 22%(Chris)

3% of 30%(Karine)

7% of 48%(Amy)

This means that:

[tex]P(A) = 0.05*0.22 + 0.03*0.3 + 0.07*0.48 = 0.0536[/tex]

Probaility of a customer not being satisfied and hair done by Chris:

5% of 22%. So

[tex]P(A \cap B) = 0.05*0.22 = 0.011[/tex]

What is the probability that their hair was done by Chris?

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.011}{0.0536} = 0.2052[/tex]

0.2052 = 20.52% probability that their hair was done by Chris
