Answer:

Step-by-step explanation:

$\frac{35}{40}=\frac{5}{x}\\\\$

Do cross multiplication

35*x=5*40

$x=\frac{5*40}{35}\\\\x=\frac{40}{7}$

Answer: $x=\frac{40}{7}$

Step-by-step explanation:

$\frac{35}{40} =\frac{5}{x}$

$\frac{7}{8} =\frac{5}{x} \\\\\frac{7}{8} x=5\\\\\frac{7x}{8} =5\\\\7x=5*8\\\\7x=40\\\\x=\frac{40}{7}$

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! :-)

pantera1 [17]

Answer:

974

Step-by-step explanation:

Initial × Increase percentage ^ Time

500 × (1 + 10%)^(70/10)

500 × 1.1^7

= 974.36

The population of the town in 70 years will be 974.

The lengths of pregnancies in a small rural village are normally distributed with a mean of 262 days and a standard deviation of

RideAnS [48]

Answer:

The range in which we can expect to find the middle 68% of most pregnancies is [245 days , 279 days].

Step-by-step explanation:

We are given that the lengths of pregnancies in a small rural village are normally distributed with a mean of 262 days and a standard deviation of 17 days.

Let X = lengths of pregnancies in a small rural village

SO, X ~ Normal( $\mu=262,\sigma^{2} = 17^{2}$ )

Here, $\mu$ = population mean = 262 days

$\sigma$ = standard deviation = 17 days

Now, the 68-95-99.7 rule states that;

68% of the data values lies within one standard deviation points.

95% of the data values lies within two standard deviation points.

99.7% of the data values lies within three standard deviation points.

So, middle 68% of most pregnancies is represented through the range of within one standard deviation points, that is;

[ $\mu -\sigma$ , $\mu + \sigma$ ] = [262 - 17 , 262 + 17]

= [245 days , 279 days]

Hence, the range in which we can expect to find the middle 68% of most pregnancies is [245 days , 279 days].

The the slope of a line is 2. Use the coordinates (3,10) of the labeled point to find the point slope equation of the line.How?

Ipatiy [6.2K]

The point slope equation of a line with slope m through point (h, k) is
y - k = m(x - h)

You have m = 2, h = 3, k = 10. Put those numbers in their place in the equation.
y - 10 = 2(x - 3)

(4x = y - 1 (6x - 2y = -3 substitution

agasfer [191]

Hey there! :)

Equation 1) 4x = y - 1

Equation 2) 6x - 2y = -3

We want both equations to match in a sense where both x & y are on the same side of the equal sign. To achieve this, simply subtract y from both sides in equation 1.

This will leave us with : 4x - y = -1

Now, line up the equations with one another.

1) 4x - y = -1

2) 6x - 2y = -3

Now, multiply 2 to ALL of equation 1.

2(4x - y = -1)

Simplify.

8x - 2y = -2 → We'll call this new equation 3. Now, line up equation 3 with equation 2.

6x - 2y = -38x - 2y = -2

Subtract equations from one another.

-2x = -1

Divide both sides by -2.

-2x ÷ -2 = -1 ÷ -2

Simplify.

x = 1/2

Now, plug in 1/2 for x into our first equation.

4x - y = -14(1/2) - y = -1

Simplify.

2 - y = -1

Subtract 2 from both sides.

-y = -1 - 2

Simplify.

-y = -3

Divide both sides by -1.

y = 3

So, our answer is : x = 1/2, y = 3 OR (1/2, 3)

~Hope I helped!~
