We can write the ratio as 2 : 5

Given is that a group of science students plans to take an SRS of 25 days in the year to see what proportion of days sampled have a low below 0°C in a particular city. Suppose that 41% of days in the city have a low temperature below 0° C.

41% of 25 = (41/100) x 25 = 10.25 = 10 days

So, we can write the ratio as -

10/25

2/5

2 : 5

Therefore, we can write the ratio as 2 : 5.

424 ÷ 8= 53

Step-by-step explanation:

Answer:  –145 is the 25th term in this series where each term is 7 less than the preceding term.

Step-by-step explanation:  Find the difference between the numbers given.

They are decreasing by 7.

The requested term is 25. Subtract -1 . = 24  (n-1)

Multiply 24 × -7 = -168

Add that to to first term

23 + (-168) = the 25th term

–145 is the 25th term in this series where each term is 7 less than the preceding term.

Answer:

Step-by-step explanation:

Let's solve your equation step-by-step.

11=−d+15

Step 1: Flip the equation.

−d+15=11

Step 2: Subtract 15 from both sides.

−d+15−15=11−15

−d=−4

Step 3: Divide both sides by -1.

−d/−1=−4/−1

Answer:

D= 4

Step-by-step explanation:

11 = -d + 15

-15        -15

-4 = -d

/-1      /-1

D=4

Answer:

The slope is -1

Step-by-step explanation:

Use the formula m=y2-y1/x2-x1

Answer:

y=1/2x+6

Step-by-step explanation:

Lines that are parallel will have the same slope, so the slope will remain 1/2. However, the y-intercepts can't be the same because then they will overlap each other instead. So we must solve for the missing y-intercept in this case:

y = 1/2x + b

4 = 1/2(-4) + b

4 = -2 + b

6 = b

b = 6

Since the y-intercept is b=6, then the equation of the line that passes through the point (-4,4) and is parallel to the line y=1/2x-4 is y=1/2x+6

Answer:

she aint correct

Step-by-step explanation:

12.00 = 12 so yea

The number 12 is an integer number because after the decimal number will be zero. So, Amata is incorrect.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

A number is the number zero, a positive regular number, or a negative number with a less sign. The negative numbers are the added substance inverses of the related positive numbers.

The number 12 is an integer number because after the decimal number will be zero. So, Amata is incorrect.

Answer:

C = 28.278  m

Step-by-step explanation:

The attached figure shows a circle whose diameter is 9 m.

Radius = Diameter/2

r = 9/2 = 4.5 m

The circumferance of the circle is given by :

C = 2πr

Put r = 4.5 m in the above formula

C = 2 × 3.142 × 4.5

= 28.278  m

So, the circumference of this circle is 28.278  m.
