Gnom [1K]

Solution :

The term 'literacy rate' provides the ability of a person who is from a definite age group can read or write.

a). $R^2$ does not determine the rate at which the variable explains another, but it explains the amount the amount of variability in one of the variables as explained by the other variable.

b). The slope given provides an expected improvement but it cannot guarantee the improvement. The value may be less or it could be more also.

The regression model provides the prediction and not the actual values.

Determine whether the triangles are similar. or not.
mr Goodwill [35]

Answer:

A

Step-by-step explanation:

We know that ∠ABE ≅ ∠DBC because they are vertical angles, so that's one pair of congruent angles. However, we can't compare ∠BAE and ∠DCB as they have different measures, so we'll have to find the measure of either ∠AEB or ∠BDC. Let's go with the former. Using the fact that the sum of the measures of the interior angles of a triangle is 180°, we know that m∠AEB=180-(53+42)=180-95=85°. Now, we know that ∠AEB ≅ ∠DCB because their measures are equal. That's another pair of congruent angles. Therefore, the angles are similar by AA. Hope this helps!

attashe74 [19]

Answer:

(C)Angle MRN and Angle NRO

Step-by-step explanation:

A diagram of the given problem is drawn and attached below.

From the diagram:

Option A: Angle PRL and Angle LRM = Angle PRM which is not 180 degrees.

Option B: Angle ORP and Angle MRN are vertically opposite angles and are therefore not linear pairs.

Option C: Angle MRN and Angle NRO are on the line ORM and therefore forms a linear pair.

<u>Therefore, the correct option is C.</u>

Katarina [22]

Answer:

35 times StartFraction 5 Over 7 EndFraction

Step-by-step explanation:

Alejandro has gone to school (5/7) of the last 35 days.

We need to find the expression that can be used to determine the number of days Alejandro has gone to school.

x=\dfrac{5}{7}\times 35\\\\=5\times 5\\\\=25

So, the correct option is (b) "35 times StartFraction 5 Over 7 EndFraction".

Start by taking away 22.36 from each side so that you are left with 4.73c = 42.57
And then divide each side by 4.73 so you will get c = 9
