1:-

$\\ \sf \longmapsto 4+8r-6r=6+2r$

$\\ \sf \longmapsto 4+2r=6+2r$

$\\ \sf \longmapsto 2r-2r=6-4$

$\\ \sf \longmapsto 0=2$

$\\ \sf \longmapsto r=\infty$

2:-

$\\ \sf \longmapsto 1-3x=-6+7-2x-x$

$\\ \sf \longmapsto 1-3x=1-3x$

$\\ \sf \longmapsto 0=0$

$\\ \sf \longmapsto x=\infty$

Answer:

dab= 43 degrees

Step-by-step explanation:

this is because of a property in geometry (I dont remember the name) that says when your lines are parallel to each other with that line through the center like that, the degrees cross

Find the measure of each angle listed below. Enter only numbers without space.

Sloan [31]

9514 1404 393

Answer:

∠PTQ = 45°
∠QTR = 15°
∠PTS = 120°

Step-by-step explanation:

Parallelogram PTSR is divided into two equilateral triangles by diagonal RT. All of the acute angles in that quadrilateral are 60°, and the obtuse angles are 120° (2×60° and also the supplement of 60°).

Triangle PTQ is an isosceles right triangle, so its acute angles are 45°.

∠PTQ = 45°

∠QTR = ∠PTR -∠PTQ = 60° -45°

∠QTR = 15°

∠PTS = 120° . . . . . . obtuse angle in PTSR; sum of ∠PTR and ∠RTS

A soft drink company has recently received customer complaints about its one-liter-sized soft drink products. Customers have bee

LUCKY_DIMON [66]

Answer:

P= 0,1379

Step-by-step explanation:

μ₀= 1,01 litres (the null hypothesis)

σ= 0,13 litres (the standard deviation)

n= 70 people (sample size)

X= 0.993 litres (the average mean)

<u>Find the probability that P(X≤ 0,993)</u>

The question requires us to calculate the probability that the dispensing unit (when functioning properly) dispenses 0,993 litres of soft drink on average.

The values mentioned above are taken from the question and can be put into the formula:

Z= $\frac{X-μ₀}{\frac{σ}{\sqrt{n} } }$

After substituting in the values into the formula, the answer is:

Z= -1,0941

This Z value can indicate on the "Standard Normal Distribution Table" the probability needed to answer the question.

After looking up the value on the table, the answer given is P= 0,1379

Conclusion:

The probability of the dispensing unit dispensing 0.993 litres or less of soft drink on average, is equal to 0,1379.
