Answer:

- 12°C

Step-by-step explanation:

Given :

Temperature in the morning = - 8°C

In the afternoon, temperature drops an additional 4°C

A temperature drop mean a reduction in the initial temperature :

Afternoon temperature = morning temperature - 4°C

Afternoon temperature = - 8°C - 4

After oon temperature = - 12°C

Answer:

7.362

Step-by-step explanation:

Given :

Mean = 35

Score, x value = 23

Zscore = - 1.63

Recall the Zscore formula :

Zscore = (X - mean) / standard deviation

-1.63 = (23 - 35) / standard deviation

-1.63 = - 12 / standard deviation

standard deviation * - 1.63 = - 12

Divide both sides by - 1.63

Standard deviation = - 12 / - 1.63

Standard deviation = 7.362

Answer: 4x^2 + 6xy + 2y^2

Step-by-step explanation:

(2x + y)(2x + 2y) =

2x*2x + 2x*2y + y*2x + y^2y =

4x^2 + 4xy + 2xy + 2y^2 =

4x^2 + 6xy + 2y^2

Answer:

4x² + 6xy + 2y²

Step-by-step explanation:

Given

(2x + y)(2x + 2y)

Each term in the second factor is multiplied by each term in the first factor, that is

2x(2x + 2y) + y(2x + 2y) ← distribute both parenthesis

= 4x² + 4xy + 2xy + 2y² ← collect like terms

= 4x² + 6xy + 2y²

Answer:

it is 12+3x your welcome

The sum of two trinomials is 4x³ + 3x then one trinomial is x³ + 2 then the other is written as 3x³ + 3x.

Let's assume the two trinomials are A and B. We are given that the sum of these two trinomials is equal to 4x³ + 3x. Mathematically, we can represent this as:

A + B = 4x³ + 3x

Now, we are also given one of the trinomials, which is x³ + 2, and we need to find the other trinomial (B).

To find B, we need to isolate it on one side of the equation. Let's rearrange the equation:

B = 4x³ + 3x - A

Now, we need to determine the value of A. We can do this by comparing the given trinomial with the general form of a trinomial, which is ax³ + bx^2 + cx.

From the given trinomial x³ + 2, we can identify that a = 1 (coefficient of x³) and b = 0 (coefficient of x²), since there is no x² term. The coefficient of x is c = 0 (since 3x = 3x¹, there is no constant term in this expression).

Now, we can write A in terms of its coefficients:

A = 1x³ + 0x² + 0x

A = x³

Now, we can substitute the value of A back into the equation for B:

B = 4x³ + 3x - x³

B = 3x³ + 3x

So, the other trinomial (B) is 3x³ + 3x.

Answer:

2 and 2/3 mph

Step-by-step explanation:

The computation of the speed when he wants to keep the same distance is shown below:

Given that

Jenny left her house at 8:00AM

Went for a school at a speed of 2 and 2/3 mph

And, her brother left the house minutes later

So here the speed would be the same i.e.  2 and 2/3 mph

Answer:

b) x = 1

Step-by-step explanation:

Given statement,

→ three halves plus one half times x is equals two x.

Forming the equation,

→ (1/2) + (1/2) + (1/2) + (1/2)x = 2x

Now the value of x will be,

→ (1/2) + (1/2) + (1/2) + (1/2)x = 2x

→ (1 + 1 + 1)/2 = 2x - (1/2)x

→ 3/2 = ((4 - 1)/2)x

→ 3/2 = (3/2)x

→ (3/2)x = 3/2

→ x = (3/2) × (2/3)

→ x = (3 × 2)/(2 × 3)

→ x = 6/6

→ [ x = 1 ]

Hence, the value of x is 1.

Answer:

32 siblings from the class theres a possibility that some students had more siblings and not everyone has one

Step-by-step explanation:

.

The probability that a student chosen randomly from the class has a brother and a sister is [tex]\frac{1}{15}[/tex].

The chance that something will happen, or how likely it is that an event will occur.

probability of an event = [tex]\frac{number of favorable outcomes}{Total number of outcomes}[/tex]

According to the given question

we have total 30 students.

6 have a brother

12 have a sister

and 14 who don't have any siblings

If we se the provided Venn diagram

the number of students who have only sister is 10

and the number of student who have only brother is 4.

because, 6+12+14 = 32

but we have only 30 students

⇒ 2 students has a brother and a sister.

therefore,

the probability that a student chosen randomly from the class has a brother and a sister = [tex]\frac{number of students as a brother and a sister}{total number of students}[/tex]= [tex]\frac{2}{30}[/tex] =[tex]\frac{1}{15}[/tex]

Hence, the probability that  the chosen student from the class has a brother and sister is [tex]\frac{1}{15}[/tex].

Coordinates of the points lying on the given line are (2, 3), (2, 5), (2, 6), (3, 5), (4, 3), (5, 4) and (7, 3)

By using the linear regression calculator,

Equation of the line of best fit → y = -0.34868x + 5.38816

Comparing this equation with, y = mx + b

Slope of the line of best fit → m = -0.34868

Answer:65

Step-by-step explanation:

Length of first, second and third piece are 5, 15 ,25 inch

Given that;

Length of board = 45 inch

Second cut is 3 times as long as the first piece

Third cut is 5 times as long as the first piece

Find:

Length of all three piece

Computation:

Assume;

Length of first piece = a

So,

Length of second piece = 3a

Length of third piece = 5a

So,

Length of first piece + Length of second piece + Length of third piece = Total length

a + 3a + 5a = 45

9a = 45

a = 5

So,

Length of first piece = a

Length of first piece = 5 inch

Length of second piece = 3a = 3(5)

Length of second piece = 15 inch

Length of third piece = 5a = 5(5)

Length of third piece = 25 inch

Step-by-step explanation:

Answer:

-7 - 4 -(-6)

-7 + - 4 - (-6)

-11 - (-6)

-11 + 6 = -5

Step-by-step explanation:

When looking at -7- 4, you can use the KCC rule, Keep, Change, Change. -7 would stay the same, but - would turn into a + and so would 4 to -4.

Now, -7 + - 4 would equal to -11. And bring down the -(-6).

When you look at two negative signs the become a positive sign, so it would now be +6.

Now, you subtract because 11 is the bigger number and you have to take it's sign, which is negative to the answer.

Therefore, your answer is -5. Hope this helps
