Answer:

Slope 'm' = [tex]\frac{5}{2}[/tex]

And y-intercept = 2

Step-by-step explanation:

Slope-intercept form of a line is given by the equation,

y = mx + b --------(1)

Here, m = slope of the line

b = y-intercept

Given equation is,

5x - 2y = -4

2y = 5x + 4

y = [tex]\frac{5}{2}x+2[/tex]

By comparing this equation with equation (1),

Slope 'm' = [tex]\frac{5}{2}[/tex]

And y-intercept = 2

Step-by-step explanation:

Step-by-step explanation:

Effective resistance in the 30Ω and 40Ω parallel circuit = 1 / (1/30 + 1/40) = 120/7 Ω.

20Ω + 10Ω = 30Ω

Effective resistance in the 50Ω and (20Ω + 10Ω) parallel circuit = 1 / (1/50 + 1/30) = 75/4 Ω.

Now we can add the resistances up:

Effective resistance for circuit

= 120/7 Ω + 75/4 Ω = 1005/28 Ω.

Hence I = V / R

= 9.0V / (1005/28 Ω) = 0.25A. (2s.f.)

Answer:

D. 1.91

(got it right on edmentum)

Step-by-step explanation:

The standard error is 1.91.

For a data set the standard error is calculated by the ratio of standard deviation and square root of the sample size.

[tex]\rm Standard \; Error= \dfrac{ \sigma}{\sqrt{n}}[/tex]

Substituting the values

Standard Deviation = 25.29

Sample size = 175

Standard Error = 25.29 / √175

Standard Error = 1.91

Therefore the standard error is 1.91.

Answer:

2/3

Step-by-step explanation:

Given:

Number of eclairs = 3

Number of humbugs =2x+6=2(x+3)  

Number of mints =  x

Therefore, total number of sweets in the jar is,

s=3+2x+6+x=3x+9=3(x+3)

Now, probability of selecting a sweet to be humbug is given as:

 p(humbug)= number of humbugs/number of sweets

p(humbug)=2(x+3)/3(x+3)=2/3

Therefore, the probability that it is a humbug is 2/3

Answer:

y intercept = 3

[tex]m = \frac{1}{3}[/tex] --- slope

Step-by-step explanation:

Given

The attached graph

Required

Determine the slope and the y intercept

The [tex]y\ intercept[/tex] is at the point where [tex]x = 0[/tex].

From the graph:

[tex]y = 3;\ when\ x = 0[/tex]

Hence,

y intercept = 3

Next, we calculate the slope using:

[tex]m = \frac{y_1 - y_2}{x_1 - x_2}[/tex]

Where:

[tex](x_1,y_1) = (0,3)[/tex]

[tex](x_2,y_2) = (9,6)[/tex]

So, we have:

[tex]m = \frac{3 - 6}{0 - 9}[/tex]

[tex]m = \frac{-3}{- 9}[/tex]

[tex]m = \frac{3}{9}[/tex]

[tex]m = \frac{1}{3}[/tex]

Answer:

Length, L = 9 feet.

Width, W = 11 feet.

Step-by-step explanation:

Given the following data;

Perimeter = 40 feet

Length = 3x

Width = 2x + 5

The perimeter of a rectangle is given by the formula;

P = 2(L + W)

40 = 2(3x + 2x +5)

40 = 2(5x + 5)

40 = 10x + 10

10x = 40 - 10

10x = 30

x = 30/10

x = 3

Now, to find the length;

Length, L = 3x

Substituting into the equation, we have;

Length, L = 3*3

Length, L = 9 feet

To find the width;

Width, W = 2x + 5

Substituting into the equation, we have;

Width, W = 2(3) + 5

Width = 6 + 5

Width, W = 11 feet.

Hey there!

When you see the word “of” in mathematical statement, it usually means “multiply” (aka Multiplication)

“3/5 of 5/9”

3/5 • 5/9

MULTIPLY the NUMERATORS (TOP NUMBERS) from each other & also MULTIPLY the DENOMINATORS (BOTTOM NUMBERS) from each other!

3(5) / 5(9)

3(5) = 15 ⬅️ NUMERATOR

5(9) = 45 ⬅️ DENOMINATOR

15/45

The GCF (Greatest Common Factor) for both of your numbers is: 15.. so DIVIDE both the NUMERATOR and DENOMINATOR from 15

15 ÷ 15 / 45 ÷ 15

15 ÷ 15 = 1 ⬅️ NUMERATOR

45 ÷ 15 = 3 ⬅️ DENOMINATOR

Answer: 1/3 ☑️

Good luck on your assignment and enjoy your day!

Answer:

The square root is 371293.

Step-by-step explanation:

We solve this question using properties of exponents.

The square root of 169 is 13, so the exponent given can be written as:

[tex]169^{5} = (13^{2})^5 = 13^{10}[/tex]

The square root of [tex]13^{10}[/tex] is given by:

[tex]\sqrt{13^{10}} = 13^{\frac{10}{2}} = 13^5 = 371293[/tex]

The square root is 371293.

Answer:

Answer: Choice G.

Step-by-step explanation:

Dilations

Suppose a point P(x,y) is dilated across the origin, that is, the origin is the center of dilation, by a scale factor k.

The image of P is P' whose coordinates are P'(kx,ky).

If an image is formed by several points and each one is dilated by the same factor, then:

If |k| > 1, the image maps to a stretched or larger image.

If |k| < 1, the image maps to a shrunk or shorter image.

We have a hexagon graphed on a coordinate grid. The hexagon is dilated to create a larger hexagon. This means k must be greater than 1 and it should multiply each original coordinate (x,y).

Options F and H don't multiply by the coordinates but add to them, thus they are not valid answers.

Option J actually multiplies by the factor 0.2 but since it's less than 1, it does not correspond to an enlargement.

Only option G multiplies by a factor 4/3=1.3 greater than 1.
