The lowest temperature with a z score of of -2.49 is 24.0 ˚F

Z scores, measures the amount of standard deviation sample X is from mean. the formula is below

z = (X - μ) / σ

Definition of variables

mean, μ = 4.4˚F

standard deviation, σ = 12.2 ˚F

X = lowest temperature

z = -2.49

substituting into the formula

-2.49 =  (X - μ) / σ

-2.49 = (X - 64.4) / 12.2

-2.49 * 12.2 = X - 64.4

-30.378 + 64.4 = X

X = 34.022

X = 34.0  (to one decimal place)

Answer:

1.0

Step-by-step explanation:

Hope this helps! :)

The solution is, 1.0 when 25/24 as a decimal rounded to the nearest tenth .

Rounding off means a number is made simpler by keeping its value intact but closer to the next number. It is done for whole numbers, and for decimals at various places of hundreds, tens, tenths, etc.

here, we have,

given that, 25/24

now, we have to rounded to the nearest tenth

as decimal, so, we have to divide 25 by 24

i.e. 25/24 = 1.041

we get, 1.041 => 1.0

so, it is 1.0  a decimal rounded to the nearest tenth

Hence, The solution is, 1.0 when 25/24 as a decimal rounded to the nearest tenth .

Answer: See attached.

Step-by-step explanation:

        This slope-intercept form equation shows us that there is a y-intercept of -7. This means that (0, -7) will be a point on the line. Next, we have a slope of positive 3. This means we will count up three units, right one unit, plot a point. Then we repeat.

Answer:

start at the y-intercept, plot some points using the slope, then connect them using a straight line.

Step-by-step explanation:

Generally you'll have an equation in slope-intercept form, which is denoted as: [tex]y=mx+b[/tex]

This is a really useful form for a couple of reasons, and it has two key features. Firstly, the "m" represents the slope of the linear equation.

This makes sense the definition of slope is: [tex]\frac{\text{change in y}}{\text{change in x}}[/tex]

and we can generally define the points:

[tex]\text{at x = 1, y = }m(1)+b\implies m+b\\\text{at x = 2, y = } m(2)+b\implies m + m + b\\\text{at x = 3, y = }m(3) + b\implies m + m + m +b\\\text{and so on...}[/tex]

as the x value increases by 1, the change in y is the "m" value, we have one more "m" than the previous x-value, so the slope is the "m" value, which is the coefficient of the x variable.

The second key feature of slope-intercept form is the y-intercept, which is represented as "b" in this form. This also makes sense because the y-intercept is simply when the x-value is zero, and if you plug in x=0 into the equation, you're only left with the "b" value

Knowing these two things we can analyze the equation given:

[tex]y = 3x-7[/tex]

since it's given in slope-intercept form, we know that slope = 3, and y-intercept = -7. We immediately know one point, which is the y-intercept, since the x-value is going to be zero at the y-intercept, so one point on the graph is: (0, -7)

now from this point we can draw the graph by going to the right one, and up three, by definition of a slope (as x increases by 1, the y-value increases by 3).

We can do something similar on the left side, except instead of right one and up three, we go left one, and down three. You may be asking why down three? Well as you go right one, you go up three, this means if you compare the previous point to the new point, the previous point is down three compared to the new point (which is to the right one), so if you were to go back, you would be going left one and down three.

Now from these points you can do the same thing to extend the line a bit, and since it's a linear equation you can connect them using a straight line.

I also attached a graph from desmos to illustrate what I was saying a bit and also show the graph.

∠C is not congruent to any angle in DEF. Hence, option C is the correct answer.

From the given figure below,

In ΔABC,

∠A=33° and ∠C=88°

By angle sum property of triangles,

∠A+∠B+∠C=180°

33°+∠B+88°=180°

∠B=180°-33°-88°  [subtracting 33° and 88° from both sides]

∠B=59°

Now, In ΔDEF,

∠D=33° and ∠E=58°

By angle sum property of triangles,

∠D+∠E+∠F=180°

33°+58°+∠F=180°

∠F=180°-33°-58°  [subtracting 33° and 58° from both sides]

∠F=89°

Thus, ΔABC is not congruent to Δ DEF as∠C and ∠B are not congruent to any angle of the Δ DEF .

Answer:

12, 24,72,96,156

Step-by-step explanation:

1/2 package would be 1/2 of 24 which is 12

21 x 24 = 24

3 x 24 = 72

4 x 24 = 72

We know that 3 packages is 72 so 6 packages is double that at 144.  We also know that have a package is 12. so 144 + 12 = 156

Answer:

1/2 package = 1/2 of 24 = 12 pencils

1 package = 24 pencils

3 packages = 24*3 = 72 pencils

4 packages = 24*4 = 96 pencils

6 1/2 packages = 24*6.5 = 156

Step-by-step explanation:

1 package = 24 pencils

1/2 package = 1/2 of 24 = 12 pencils

1 package = 24 pencils

3 packages = 24*3 = 72 pencils

4 packages = 24*4 = 96 pencils

6 1/2 packages = 24*6.5 = 156

The width and the length of the slab are 2 meters and 12 meters, respectively

From the question, we have the following parameters that can be used in our computation:

Width of a rectangular slab of concrete = 10m less than the length.

Area = 24 m²

These parameters can be represented as

Width = Length - 10

Area = Length * Width

So, we have

w = l - 10

A = lw

Also, we have

A = 24

Substitute w = l - 10 in A = lw

A = l(l - 10)

So, we have

l(l - 10) = 24

Expand

l² - 10l = 24

This gives

l² - 10l - 24 = 0

Expand

l² + 2l - 12l - 24 = 0

Factorize

(l + 2)(l - 12) = 0

So, we have

l = -2 and l = 12

The length cannot be negative

So, we have

l = 12

Recall that

w = l - 10

So, we have

w = 12 - 10

Evaluate

w = 2

The function of piecewise graph shown in the figure is,

f(x) = {y = 6   for x < -5

        { [tex]y = -\frac{19}{9}x-\frac{5}{9}[/tex]    for -5 ≤x < 5

        { y = 8/5x -14   for x ≥ 5

What is piecewise function?

A piecewise-defined function in mathematics is a function with several sub functions, each of which has a certain interval in the domain for which it is applicable. Piecewise definition is a method of expressing the function, not a property of the function.

From graph we can see that the first function is a line y = 6

Hence, f(x) = {y = 6    for x < -5}

Now to find the equation of second function.

From graph we get two points (-5, 10) and (4, -9).

First to find the slope

[tex]m = \frac{-9-10}{4+5} = \frac{-19}{9}[/tex]

Now to find the equation of line, using slope point form

[tex]y - 10 = \frac{-19}{9} (x-(-5))\\y-10=-\frac{19}{9}x-\frac{95}{9} \\ y=-\frac{19}{9}x-\frac{95}{9} + 10\\y = -\frac{19}{9}x -\frac{5}{9}[/tex]

So, f(x) = { [tex]y= -\frac{19}{9}x-\frac{9}{5}[/tex],    for -5 ≤ x < 5}

Now to find the equation of third line.

From graph we get two points (5, -6) and (10, 2).

First to find the slope of the line

[tex]m = \frac{2-(-6)}{10-5} = \frac{8}{5}[/tex]

Now to find the  equation of line, using slope point form

[tex]y-(-6)=\frac{8}{5}(x-5)\\ y+6=\frac{8}{5}x-8\\ y = \frac{8}{5}x - 14[/tex]

So, f(x) = {[tex]y = \frac{8}{5}x-14[/tex],   for x ≥ 5}.

Prices of two ratios in the ratio is 4 : 1.

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Ratios can be classified into two types. One is part to part ratio and the other is part to whole ratio. The part-to-part ratio denotes how two distinct entities or groups are related.

For example, the ratio of boys to girls in a class is 12: 15, whereas, the part-to-whole ratio denotes the relationship between a specific group to a whole.

For example, out of every 10 people, 5 of them like to read books. Therefore, the part to the whole ratio is 5: 10, which means every 5 people from 10 people like to read books.
