The high temperatures (in degrees Fahrenheit) of a random sample of 5 small towns are: 99.6 99.7 97.9 98.6 97.7 Assume high temperatures are normally distributed. Based on this data, find the 99% confidence interval of the mean high temperature of towns. Enter your answer as an open-interval (i.e., parentheses) accurate to two decimal places (because the sample data are reported accurate to one decimal place).

Answer:

4 + 1/3 = 13/3

4/5 + 1/3 = 17/15

Step-by-step explanation:

Brain-List?

Answer:

1.) 4 1/3, 2.) 1 2/15

Step-by-step explanation:

4 + 1/3 is 4 1/3, I got this by adding the fraction to the whole number to make a mixed number. For 4/5 + 1/3, we need to find a common denominator, let's find the LCM (Lowest Common Multiple) of 3 and 5, the LCM is 15. Now, we need to multiply 1/3 by 5/5, and we need to multiply 4/5 by 3/3. This gets us 5/15+12/15. We only need to add the top numbers. This gets us 17/15. Since this is an improper fraction, we need to make it into a mixed number, this gets us 1 2/15. I hope this helps!

AC = 46

AB + BC = AC

(4x + 7) + (3x + 4) = 46

4x + 7 + 3x + 4 = 46

(4x + 3x) + (7 + 4) = 46

7x + 11 = 46

7x = 46 - 11

7x = 35

x = 35/7

x = 5

AB = 4x + 7

AB = 4(5) + 7

AB = 20 + 7

AB = 27

BC = 3x + 4

BC = 3(5) + 4

BC = 15 + 4

BC = 19

Answer:

(22;-3)

Step-by-step explanation:

if to calculate the coordinates of the given midpoint it needed to use:

[tex]x_{midpoint}=\frac{x_{endpoint1}+x_{endpoint2}}{2};[/tex]

[tex]y_{midpoint}=\frac{y_{endpoint1}+y_{endpoint2}}{2};[/tex]

then to calculate the coordinates of endpoint2, it needed to perform the substitution:

[tex]\frac{-10+x_{endpoint2}}{2}=6,[/tex]

[tex]2=\frac{7+y_{endpoint2}}{2},[/tex]

finally:

[tex]x_{endpoint2}=22;[/tex]

[tex]y_{endpoint2}=-3.[/tex]

Answer:

Option (5)

Step-by-step explanation:

Graph of a function f(x) = x represents a straight straight line (y = x), passing through the origin (0, 0).

As shown in the graph,

Let the equation of the given line is,

y = mx + b

Here, m = slope of the line

b = y-intercept

Since, the given line passes through two points (0, -1) and (-1, 2)

Slope of the line 'm' = [tex]\frac{y_2-y_1}{x_2-x_1}=\frac{2+1}{-1-0}[/tex]

                                              = -3

y-intercept 'b' = -1

Therefore, equation of the line will be,

y = -3x - 1

And the function is,

g(x) = -3x - 1

Here, (-3) represents the reflection of parent function over the x axis, vertical stretch of the parent function by 3 units.

Followed by the shifting of parent function by 1 unit down.

Therefore, Option (5) is the answer.

Answer:

Step-by-step explanation:

========================================================

Explanation:

Let's start with the exterior angle 116 degrees.

The interior angle adjacent to this will add to 116 and we'll get 180

(interior angle) + (exterior angle) = 180

(angle VWX) + (angle VWY) = 180

(angle VWX) + (116) = 180

angle VWX = 180 - 116

angle VWX = 64

-----------------

Let's focus solely on the interior angles of triangle VWX

We found angle W to be 64. Angle X is given to be 44. Angle V is unknown, but we can solve for it like such

V+W+X = 180

V+64+44 = 180

V+108 = 180

V = 180-108

V = 72

--------------

The three interior angles of triangle VWX are:

V = 72

W = 64

X = 44

This will determine the order of the side lengths from smallest to largest. Recall that the smallest side of a triangle is always opposite the smallest angle. Similarly, the largest side is always opposite the largest angle.

Based on those V,W,X angle values, we know that

WX = longest side (since the angle opposite V = 72 is largest)

VW = shortest side (since X = 44 is the smallest angle and it is opposite VW)

The order of the sides is therefore:

VW < VX < WX

We don't involve point Y because it's not part of the triangle.

Hence, the fraction of the counters are blue is given as 5/9

Answer:

The equation that passes through (−7,−3)and (−2,−1) is y=2/5x-1/5

Step-by-step explanation:

m=y²-y¹/x²-x¹

m=(-1)-(-3)/(-2)-(-7)

m=2/5

y-y=m(x-x¹)

y-(-1)=2/5(x-(-2)

y+1=2/5x+4/5

Answer:

a. [tex]0.00004167 = 0.00004[/tex]

b. [tex]4* 10^{-5}[/tex]

Step-by-step explanation:

Given

[tex]0.00004167[/tex]

Solving (a): Round to the nearest hundredth thousandth

This means there would be 5 digits after the decimal.

So:

[tex]0.00004167 = 0.00004[/tex] -- (approximated)

(b) Express in standard form

A number in standard form has the following format;

[tex]a * 10^b[/tex]

Where

[tex]1 \leq a \leq 10[/tex]

So:

[tex]0.00004167[/tex]

becomes

[tex]4.167 * 10^{-5}[/tex]

This is because the decimal point was moved 5 places backwards

Approximate 4.167 to nearest integer; We have:

[tex]4* 10^{-5}[/tex]

Answer:

The distance between the points (-3, -6) and (5, 9) is 15 units.

Step-by-step explanation:

Given the points

First, we need to find the distance between the two x-coordinates. For this, we need to count the distance from 0 to another point. Then we just add them together.

i.e.

-3 to get to 0 takes 3 units

0 to 5 takes 5 units

3+5=8 units

Just do the same for y-coordinate

From -6 to 0 takes 6 units

0 to 9 takes 9 units

6+9 = 15 units

Therefore, we get the base and height.

Now using the Pythagoras' Theorem to find the distance:

c² = 8² + 15²

c² = 289

[tex]\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}[/tex]

[tex]c=\sqrt{289},\:c=-\sqrt{289}[/tex]

[tex]c=17,\:c=-17[/tex]

As the distance can not be negative.

so

Thus, the distance between the points (-3, -6) and (5, 9) is 15 units.

Answer:

there are 12 boys because 32/8 =4 and the ratiots 3 to 8 which means you need to multiply 3 by 4 which gives you 12

Step-by-step explanation:

Answer:

44 members

Step-by-step explanation:

Because to find out the number of members first you have to find out the number of boys in choir

Divide total number of girls (32) by ratio number (8) and you get 4

Multiply the 4 you got by the ratio of boys (3), you get 12 when you multiply these together

Add the total number of boys in choir (12) and number of girls (32) and you get 44 members!

Good day to you and I hope you like my explination.

Step-by-step explanation:

To find the formula for the nth term ,

First , find the common difference or common ratio.

Common difference =

[tex]T_2-T_1 \\ - 2 - 3 \\ = - 5[/tex]

Common ratio =

[tex]T_2/T_1 \\ \frac{ - 2}{3} [/tex]

The common difference applies to the other given numbers for example :

[tex]T_3- T_2 = - 7 - ( - 2) \\ = - 7 + 2 = - 5[/tex]

this proves that it is an arithmetic sequence and the given formula for the nth term of an arithmetic sequence is

T_n =a(n-1)d

Where n = no of terms

a= first term

d= common difference

Answer:

25 = 50%

37.50 = 75%

75 = 150%

Step-by-step explanation:

We know that 50 is 100% so we can work with that.

We also know the percentages increase by 25% for every $12.5.

12.50 + 12.50 = 25

25 + 12.50 = 37.50

62.50 + 12.50 = 75

25 = 50%

37.50 = 75%

75 = 150%

Answer:

D. 15 cm, 9 cm, 24 cm

Step-by-step explanation:

The three lengths that could be the lengths of the sides of a triangle, must satisfy the following condition;

---sum of any two smaller sides chosen must be equal to the third side.

Test option A : 6 cm + 11 cm = 17 cm  ( 17 cm ≠ 23 cm)

Test option B: 10 cm + 15 cm = 25 cm (25 cm ≠ 24 cm)

Test option C: 6 cm + 6 cm = 12 cm (12 cm ≠ 22 cm)

Test option D: 15 cm + 9 cm = 24 cm (24 cm = 24 cm) ---correct option.

Thus, the three lengths that could be the lengths of the sides of a triangle are 15 cm, 9 cm, and 24 cm
