Answer:

-2 2/3

Step-by-step explanation:

3+(-5 and 2/3)=3-5 2/3= -5 2/3+3=-2 2/3

The sum of two numbers is [tex]-2\frac{2}{3}[/tex] .

To add fractions there are three simple steps:

Step 1: Make sure the bottom numbers (the denominators) are the same. Step 2: Add the top numbers (the numerators), put that answer over the denominator.

Step 3: Simplify the fraction (if possible)

Given that, 3+([tex]-5\frac{2}{3}[/tex])

= 3-17/3

= (9-17)/3

= -8/3

= [tex]-2\frac{2}{3}[/tex]

Therefore, the sum of two numbers is [tex]-2\frac{2}{3}[/tex] .

Answer:

Linear

Step-by-step explanation:

Notice that x values increase by 1 each row and that the y values increase by 5 each row. By definition, in linear functions, x and y values both increase by constant values. Going down each row, the y value increases by 5 as the x value increases by 1, so we know that the graph must be a linear function.

Function Type: linear

Equation: y = 5x + 7

When you win 25% of the time based on the probability, this illustrates that the number of products picked will be 7 products.

Based on the information given, the following can be depicted. It should be noted that there are 6 sides as well as 4 cards.

Therefore, the numbers on the dice i.e from 1 - 6 will be represented 4 times each. This gives a total of (4 × 6) = 24. There are also 4 cards. The total in sample space will now be:

= 24 + 4 = 28

The frequency table will be such that 28 or more have a relative frequency of 9. Therefore, the probability that a person wins the game will be:

= 9/28 = 32.1%

When you win 25% of the time, this illustrates that the number of products picked will be:

= 25% × 28

= 7 products.

The probability of participants achieving a winning score of 36 or higher in four consecutive attempts will be:

The value of DF = 20.

Two objects are similar if they have the same shape, or one has the same shape as the mirror image of the other.

Given:

Using theorem

If two triangles are similar, then the ratio of the area of both triangles is proportional to the square of the ratio of their corresponding sides.

ΔSDF/Δ RTY = (SD/RT)= (DF/TY)=  (FS/ YR)

ar ΔSDF² / ar  ΔRTY² = 16/81

SD/ RT = 4/9

SD = 4x,  RT= 9x

SD= 8

4x = 8

x = 2

So,

RT=  9*2 = 18

SF = RT -2

SF = 16

(SD/RT)= (FS/ YR)

8 / 18 = 16/ YR

YR= 36

TY= 9 +RY = 45

Answer:

60 degrees

Step-by-step explanation:

Since all three sides are the same length, all three angles must be the same size.  This means the triangle is an equilateral triangle

The angles are 60 degrees

Answer:

Hello! The answer is 60°.

Step-by-step explanation:

As marked by the dashes on each side, the sides are congruent. If the sides are congruent, this means that the angle measures are equal.

Having three equal sides is an equilateral triangle, and the total angle measure sum is 180.

To find the measure of angle y, you will have to divide the total angle measure by the number of angles:

180 ÷ 3 = 60

The measure of angle y = 60°

Step-by-step explanation:

Arc length = 2πr ( θ / 360 )

Here,

θ = 90

r = 90 ft

Arc length = 2πr ( θ / 360 )

Arc length = ( 2π * 16 ) ( 90 / 360 )

                 = ( 2π * 16 ) ( 1 / 4 )

Arc length = 8π ft

Answer:

B

Step-by-step explanation:

the arc length is calculated as

arc = circumference of circle × fraction of circle

The first proof that organic molecules required for life might be created from inorganic elements was supplied by the Miller-Urey experiment.

The section of the zoo is a right triangle. The new path is in front of the right angle, therefore it is the hypotenuse. To find the length of the hypotenuse we use the Pythagorean theorem:

H² = P² + B²

Given that the hypotenuse is of length 2 and legs of length x+1 and x-1. The value of x will be calculated as:-

H² = P² + B²

2² = ( x + 1 )² + ( x - 1 )²

Answer:

28 legs are on the floor once again

There are no legs on the floor.

Hence answer is zero.

According to the question,

For 2 dogs: Each dog has 4 legs.

Therefore, 2 dogs have a total of 8 legs.

For 4 horses: Each horse has 4 legs.

Therefore, 4 horses have a total of 16 legs.

For 1 giraffe: A giraffe has 4 legs.

For 1 duck: A duck has 2 legs.

For 3 hens: Each hen has 2 legs.

Therefore, 3 hens have a total of 6 legs.

To get the total number of legs on the bed,

we simply add up all the legs of the animals on the bed,

⇒ 8 legs + 16 legs + 4 legs + 2 legs + 6 legs = 36 legs.

Now, to get the number of legs on the floor,

We need to subtract the number of legs on the bed from the total number of legs of all the animals,

For 2 dogs with a total of 8 legs.

For 4 horses with a total of 16 legs.

For 1 giraffe with 4 legs.

For 1 duck with 2 legs.

For 3 hens with a total of 6 legs.

So, the total number of legs of all the animals is,

⇒ 8 legs + 16 legs + 4 legs + 2 legs + 6 legs = 36 legs.

Since all the animals are on the bed,

There are no legs on the floor.

The sample mean = μ - 3685 grams.

The sample standard deviation (s) = σ/√n = 575/√113 = 54.09145.

We are asked to find the probability that the mean weight of the sample babies is less than 3631 grams, that is,

P(X < 3631)  = P(Z < {(3631 - 3685)/54.09145})

Using the formula: Z = (x - μ)/s,
