Answer:

1+y [tex]\leq[/tex] -13

Step-by-step explanation:

The problem states that one plus y is No greater than -13.

This means that is less than or equal to -13.

It also gives you one plus y, or 1+y

Put everything together to get 1+y [tex]\leq[/tex] -13

Answer:

C. At the 0.01 level of significance, the mean mass of the apples grown in the farmer's orchard is different from 100g.

Step-by-step explanation:

The null hypothesis is:

[tex]H_{0} = 100[/tex]

Because of the claim of the farmer.

The alternate hypothesis is:

[tex]H_{1} \neq 100[/tex]

The alternate hypothesis tests the farmer's claim at a significance level.

The results are calculated to be statistically significant at the 0.01 level.

This means that at the 0.01 level, the null hypothesis is rejected, that is, the mean mass of the farmer's orchard is different from 100. Since it is significant at the 0.01 level, it will be significant at the 0.05, 0.1, and increasing levels. So the correct answer is given by option C.

Answer:

The pooled estimate of the common variance is approximately 639.59

Step-by-step explanation:

The given parameters are;

The number of shops Emily visited, n₁ = 12 shops

The average repair estimate Emily was given, [tex]\overline x_1[/tex] = $85

The standard deviation of the estimate Emily was given, s₁ = $28

The number of shops John visited, n₂ = 9 shops

The average repair estimate John was given, [tex]\overline x_2[/tex] = $65

The standard deviation of the estimate John was given, s₂ = $21

The pooled estimate of the common variance, [tex]s_p^2[/tex], is given as follows;

[tex]s_p^2 = \dfrac{(n_1 - 1)\cdot s_1^2+(n_2 - 1)\cdot s_2^2}{n_1 + n_2-2}[/tex]

[tex]\therefore s_p^2 = \dfrac{(12 - 1)\cdot 28^2+(9 - 1)\cdot 21^2}{12 + 9-2} = 639.578947368[/tex]

∴ The pooled estimate of the common variance, [tex]s_p^2[/tex], ≈ 639.59

Answer:

Side length:11

Area: 121

Step-by-step explanation:

if its a square all sides should be equal so you can divide 44 by 4 which gives you 11 and then to find area you just multiply the two sides together which would be 11x11 and that equals 121

I'm pretty sure this is what it would be but it also seems over simplified and i might be missing something?

Answer: 35/100

Step-by-step explanation: percents are always out of 100, so 100 will always be in the denominator.

Answer:

35/100

Step-by-step explanation:

35% is from 100%, so same for the fraction form 35/100

The solution for y in the equation 48/y = 12 is y = 4 .

To solve for y in the equation 48/y = 12, we can multiply both sides of the equation by y to eliminate the denominator:

48/y * y = 12 * y

On the left side, the y in the denominator cancels out:

48 = 12 * y

Next, divide both sides of the equation by 12 to isolate y :

48/12 = y

Simplifying, we get:

4 = y

Therefore, the solution for y in the equation 48/y = 12 is y = 4 .

Answer:

6 hour and 110 Min

Step-by-step explanation:

Answer:

7 hours and 59 minutes

Step-by-step explanation:

1 hour 52 minutes = 60 + 52 = 112 minutes

2 hours 6 minutes= 120+6 =126 minutes

2 hours 3 minutes = 120 +3= 123 minutes

1 hour 58 minutes = 60 + 58 = 118 minutes

Total number of minutes / 60 minutes= # hours + minutes

479/60= Approximately 8 hours. It is 7 hours and 59 minutes to be exact.

Complete Question:

Johnny printed two maps of a walking trail near his home. The length of the walking trail on the first map is 8 cm.

(a) Choose a length between 5 cm and 15 cm for the walking trail on the second map: ________cm.  

(b) Determine the scale factor from the first map to the second map.

(c)  A landmark on the first map is a triangle with side lengths of 3 cm, 4 cm, and 5 cm. What are the side lengths of the triangle landmark on the second map?  

(d) Draw one of the triangles from part C. Label the side lengths and vertices accordingly. You may use this drawing tool or draw your triangle on paper:

Answer:

(a) Length = 4cm

(b) Scale factor = 0.5

(c) 3cm, 4cm and 5cm are represented by 1.5cm, 2cm and 2.5cm respectively, on the second scale

(d) See attachment for triangle

Step-by-step explanation:

(a) Choose a length between 5 cm and 15 cm

[tex]Length =4cm[/tex] --- This is solely up to you (you can make use of any length between 5 cm and 15 cm)

(b) The scale factor

The scale factor (k) is calculated as:

[tex]k = \frac{New\ Length}{Old\ Length}[/tex]

[tex]k = \frac{4cm}{8cm}\\[/tex]

[tex]k = 0.5[/tex]

(c) What are side lengths of 3 cm, 4 cm, and 5 cm on the second landmark

Using:

[tex]k = \frac{New\ Length}{Old\ Length}[/tex]

The old lengths, in this case are: 3cm, 4cm and 5cm

Make New length the subject

[tex]New\ Length = k * Old\ Length[/tex]

When [tex]Length = 3cm[/tex]

[tex]New\ Length = 0.5 * 3cm = 1.5cm[/tex]

When [tex]Length = 4cm[/tex]

[tex]New\ Length = 0.5 * 4cm = 2cm[/tex]

When [tex]Length = 5cm[/tex]

[tex]New\ Length = 0.5 * 5cm = 2.5cm[/tex]

So: 3cm, 4cm and 5cm are represented by 1.5cm, 2cm and 2.5cm respectively, on the second scale

Answer:

The straight-line distance between the points is approximately 8.6.

Step-by-step explanation:

The straight-line distance ([tex]d[/tex]) between the points is determined by the following Pythagorean identity:

[tex]d = \sqrt{x^{2}+y^{2}}[/tex] (1)

Where:

[tex]x[/tex] - Horizontal distance between the points.

[tex]y[/tex] - Vertical distance between the points.

Let consider that each square has a distance of 1 unit. If we know that [tex]x = 5[/tex] and [tex]y = -7[/tex], then the straight-line distance is:

[tex]d = \sqrt{5^{2}+(-7)^{2}}[/tex]

[tex]d \approx 8.6[/tex]

The straight-line distance between the points is approximately 8.6.
