$- 2x + 5 < 7$

$- 2x < 7 - 5$

$- 2x < 2$

$- x < \frac{2}{2}$

$- x < 1$

$x < - 1$

So, Answer is " x< -1"

Hope it helps you...

Recent census data indicated that 14.2% of adults between the ages of 25 and 34 live with their parents. A random sample of 125

kicyunya [14]

Answer:

The probability is $P(14 < X < 20 ) = 0.5354$

Step-by-step explanation:

From the question we are told that

The proportion that live with their parents is $\r p = 0.142$

The sample size is n = 125

Given that there are two possible outcomes and that this outcomes are independent of each other then we can say the Recent census data follows a Binomial distribution

i.e

$X \ \~ \ B( \mu , \sigma )$

Now the mean is evaluated as

$\mu = n * \r p$

$\mu = 125 * 0.142$

$\mu = 17.75$

Generally the proportion that are not staying with parents is

$\r q = 1 - \r p$

= > $\r q = 0.858$

The standard deviation is mathematically evaluated as

$\sigma = \sqrt{n * \r p * \r q }$

$\sigma = \sqrt{ 125 * 0.142 * 0.858 }$

$\sigma = 3.90$

Given the n is large then we can use normal approximation to evaluate the probability as follows

$P(14 < X < 20 ) = P( \frac{ 14 - 17.75}{3.90}$

Now applying continuity correction

$P(14 < X < 20 ) = P( \frac{ 13.5 - 17.75}{3.90} < \frac{ X - \mu }{\sigma } < \frac{ 19.5 - 17.75}{3.90} )$

Generally

$\frac{ X - \mu }{\sigma } = Z ( The \ standardized \ value \ of X )$

$P(14 < X < 20 ) = P( \frac{ 13.5 - 17.75}{3.90} < Z< \frac{ 19.5 - 17.75}{3.90} )$

$P(14 < X < 20 ) = P( -1.0897 < Z< 0.449 } )$

$P(14 < X < 20 ) = P( Z< 0.449 ) - P(Z < -1.0897)$

So for the z - table

$P( Z< 0.449 ) = 0.67328$

$P(Z < -1.0897) = 0.13792$

$P(14 < X < 20 ) = 0.67328 - 0.13792$

$P(14 < X < 20 ) = 0.5354$

If Mike can tune 4 cars in 3 hours. How many cars can Mike tune in 8 hours?

motikmotik

Answer:

10 2/3 cars

Step-by-step explanation:

We can use a ratio

4 cars x cars

------------- = -----------

3 hours 8 hours

Using cross products

4 *8 = 3 *x

32 = 3x

Divide each side by 3

32/3 = 3x/3

10 2/3 cars

A wet bicycle tire leaves a trace of water on the floor. The tire has a radius of 30 \text{ cm}30 cm30, start text, space, c, m,

Annette [7]

Answer:

186 cm

Step-by-step explanation:

Since the bicycle wheel is making a rotation and not a revolution, the bicycle wheel is at one point.

The length of the trace of water left on the floor is simply the circumference of the bicycle wheel

Circumference = 2πR

where R = radius of the bicycle wheel

and π = pie

Circumference = 2 × (22/7) × 30 = 188.57143 cm
