Answer:

$122.72 (Aprox)

Step-by-step explanation:

1 ft = 12 inches

2 inches = 2/12 = 0.166667 ft

then:

9ft 2 in = 9.166667 ft

Proportions:

9.1666667 ft ⇒ $15

75 ft ⇒ $A

A = 75ft * $15 / 9.1666667ft

A = $122.72 (Aprox.)

Answer: 120 (Rounded) or 122.7 (Non-Rounded)

Step-by-step explanation:

To start off, let's convert the 9 feet 2 inches and 75 feet into equivalent numbers. 9 feet 2 inches is 110 inches (Since 9 times 12 is 108, and add the 2 and you get 110) , and 75 feet is 900 inches. (75 times 12, since 12 inches are in a foot). If 110 is $15, and 900 is an unknown, we can take a look at the two in this way:

15/110=?/900

To find our answer, let's start by dividing 900 by 110; this equals about 8.18

So now we can take the 15 and multiply by 8.18.

Now this makes our fractions equivalent and gives us our answer of 122.7

Now, if 8.18 is rounded, consider your answer 120

(I can't give a definite answer other than 122.7 or 120 since this isn't multiple choice so I can't tell to round or not.)

Hope this helps!

To prove the QRST is a parallelogram.

Step 1: Given $\angle T \cong \angle R$ and $\overline{Q R} \| \overline{T S}$

Step 2: $\angle R Q S \text { and } \angle T S Q$ are alternate interior angles.

Definition of alternate interior angles

Step 3: Alternate interior angle theorem:

If two parallel lines cut by a transversal then the alternate interior angles are congruence.

QR and TS are parallel lines cut by QS.

Therefore, $\angle R Q S \cong \angle T S Q$

Step 4: Reflexive property of congruence:

Any geometric figure is congruence to itself.

Therefore, $\overline{Q S} \cong \overline{Q S}$

Step 5: By the above steps

$\angle T \cong \angle R$ (Angle), $\angle R Q S \cong \angle T S Q$ (Angle) and $\overline{Q S} \cong \overline{Q S}$ (Side)

Hence $\triangle Q T S \cong \triangle S R Q$ (by ASA congruence theorem)

Step 6: Corresponding parts of congruence triangles are congruent.

$\Rightarrow \ \overline{Q R} \cong \overline{T S}$

Step 7: Property of parallelogram:

If one pair of opposite sides are both parallel and congruent, then the quadrilateral is a parallelogram.

Hence Quadrilateral QRST is a parallelogram.

2. What is the slope of the line? -1/4 -3/4 3/4 4/3

Leni [432]

The slope of your line is 3/4 because your y-intercept is 0. You can see that your other point you can look at is (4,3). You can go UP three and OVER four to get to that place. Therefore, your slope is 3/4.

A sanitation department is interested in estimating the mean amount of garbage per bin for all bins in the city. In a random sam

bekas [8.4K]

Answer:

The 95.7% confidence interval for the expected amount of garbage per bin for all bins in the city

(48.937 , 50.863)

Step-by-step explanation:

Explanation:-

Given data random sample of 46 bins, the sample mean amount was 49.9 pounds and the sample standard deviation was 3.641

The sample size 'n' =46

mean of the sample x⁻ = 49.9

Standard deviation of the sample S = 3.641

Confidence intervals:-

The 95.7% confidence interval for the expected amount of garbage per bin for all bins in the city

$(x^{-} - t_{\alpha } \frac{S}{\sqrt{n} } ,x^{-} + t_{\alpha } \frac{S}{\sqrt{n} })$

Degrees of freedom = n-1 = 46-1 =45

The tabulated value t₀.₉₆ = 1.794 ( from t-table)

$(49.9 - 1.794 \frac{3.641}{\sqrt{46} } ,49.9+ 1.794 \frac{3.641}{\sqrt{46} })$

(49.9 -0.9630 , 49.9+0.9630)

(48.937 , 50.863)

Conclusion:-

The 95.7% confidence interval for the expected amount of garbage per bin for all bins in the city

(48.937 , 50.863)
