I'm assuming you want us to solve this inequality for x, since the question wasn't too clear on that.

$x - 35 > 15$

Add 35 to both sides to remove the "-35" on the left side so we can isolate the x

$x-35+35>15+35$

$x>50$

The solution to this inequality is x>50. Let me know if you need any clarifications, thanks!

9. What is the likelihood that a randomly selected couple's relationship survived between 90 and 150 days

andrew-mc [135]

Answer:

0.5818

Step-by-step explanation:

Suppose the average teenage romantic relationship is normally distributed with a mean number of 100 days with a standard deviation of 30 days.

Answer:

The z score is used to determine how many standard deviations that the raw score is above or below the mean. If the z score is positive then the raw score is above the mean and if it is negative then it is below the mean. It is given by:

$z=\frac{x-\mu}{\sigma}\\ \\where\ \mu=mean,\sigma=standard\ deviation, x=raw\ score$

Given that:

$\mu=100\ days,\sigma=30\ days\\\\For\ x=90\\\\z=\frac{90-100}{30} =-0.33\\\\For\ x=150\\\\z=\frac{150-100}{30} =1.67$

Therefore, from the normal distribution table, P(90 < x < 150) = P(-0.33 < z < 1.67) = P(z < 1.67) - P(z < -0.33) = 0.9525 - 0.3707 = 0.5818

If m 2 n, which inequalities must be true? Check all that apply.

anzhelika [568]

Answer:

$(a)\ m+ 2.1 > n + 2.1$

$(b).\ m - (-4) > n - (-4)$

$(c)\ 9 +m> 6 + n$

Step-by-step explanation:

Given

$m > n$

Required

Select true inequalities

$(a)\ m+ 2.1 > n + 2.1$

Subtract 2.1 from both sides

$m > n$

This is true

$(b).\ m - (-4) > n - (-4)$

Open brackets

$m + 4 > n + 4$

Subtract 4 from both sides

$m > n$

$(c)\ 9 +m> 6 + n$

$m> -9+6 + n$

$m> n-3$

This is also true

The radius of a circle is 13miles. what is the area of a sector bounded by a 20 degree arc

Stolb23 [73]

Answer:

Area of the sector = 29.48 square miles.

Step-by-step explanation:

Given:

Radius of a circle = 13 miles

Angle bounded by the arc = 20 deg

To find

Area of the sector bounded by 20 degrees.

Note: Area of a sector = $\frac{(\theta)}{360}\times \pi\times r^2$

Plugging the values in the equation.

⇒ $\frac{(\theta)}{360}\times \pi\times r^2$

⇒ $(\frac{20}{360})\times 3.14\times 13^2$

⇒ $29.48$ square-miles

So the area of the sector bounded by 20 degree arc is 29.48 square miles.
