Complete question is;

RS is the perpendicular bisector of PQ . Point T is the midpoint of PQ. Point U lies on RS. If the length of UP is 7 units, the length of UQ is ______ units.

Triangle is attached

Answer:

UQ = 7 Units

Step-by-step explanation:

From the image attached, we can see that;

T is the midpoint of PQ

Thus;

PT = TQ

Since RS is perpendicular to PQ, then we can say that;

∠PTU = ∠QTU

Now, from SAS congruence theorem, we can say that;

△PTU = △QTU

Thus, from corresponding sides of both triangles, we can say that;

UP = UQ

Thus,

UQ = 7 Units

You know that there is a strong correlation between the consumption of ice cream and body weight. The Pearson's r = 0.78. You al
Naddika [18.5K]

Answer:

y = 7.8x + 26

Step-by-step explanation:

Given the following :

Pearson's r = 0.78

Average consumption of ice cream = 5 grams per week (m) with Standard deviation (sd) = 1.5 grams

Average weight = 65 kg with standard deviation of 15kg

Formular for the regression line :

General regression formula :

y = mx + c

y = predicted variable ; m = slope or gradient ; x = predictor variable ; c = intercept

Gradient (m) = change in y / change in x

m = (sd y / sd x) * r

m = (sd weight / sd ice cream) × r

m = (15 / 1.5) × r

m = 10 × 0.78 = 7.8

Intercept:

mean of weight(y) - [Slope×mean of icecream(x)]

65 - [7.8 × 5]

65 - 39 = 26

Hence,

y = 7.8x + 26

2. (-2, 5)

(-2-8, 5+4)

<u>(-10, 9)</u>

3. (-3, -10)

(-3-8, -10+4)

ídk man u should connect it to <u>(11, -7)</u> since it's the only choice closest to the right answer, but If u can write the correct then write this. there's prolly an error in that quiz ídk

4. (3, -3)

(3-8, -3+4)
