Formula used: 40+x = 4x-3 x is used for ET

Step-by-step explanation:

40+x = 4x-3

+3 +3

43+x = 4x

-x -x

43 = 3x

3 3

14.3 = x

then substitude this on 5x+3 on WT and you arr good

A random sample of 300 balls hit into play in college baseball games is taken. For each ball hit into play, it is recorded wheth

Soloha48 [4]

Answer:

(D) H_0H0: The direction of the ball and whether it results in a hit or an out are independent.

Step-by-step explanation:

Given that

There is 300 balls random sample is taken

We need to find out the appropriate null hypothesis that lies between the ball direction and lead to a hit or an out

Based on the given options, the option d is correct as the ball direction and its results either be hit or on out would represent that they are independent

Therefore the option d is correct

Find the midpoint of points A(-9, -3) and B(1, 7) graphically. Plot the line segment AB

Reptile [31]

Answer: (-4,2)

Step-by-step explanation:

To find the midpoint of AB, we have to find the mean of the x coordinates for the x coordinate of the midpoint and the mean of the y coordinates for the y coordinate of the midpoint

So the midpoint is ((-9+1)/2,(-3+7)/2) = (-4,2)

To plot the line AB, just find the points A and B on the graph and draw a straight line from A to B

Convert the scientific notation into a standard form number, 1.23 x 10-5

marusya05 [52]

Step-by-step explanation:

$a^{-n}=\dfrac{1}{a^n}\\\\\text{therefore}\ 10^{-5}=\dfrac{1}{10^5}=\dfrac{1}{100000}=0.00001\\\\1.23\cdot10^{-5}=1.23\cdot0.00001=0.0000123$

$a\cdot10^{-n}$ - move the decimal point n place to the left

$a\cdot10^n$ - move the decimal point n place to the right

Examples:

$1.2\cdot10^5=1\underbrace{20000}_{5\to}=120,000\\\\1.2\cdot10^{-5}=0\underbrace{.00001}_{\leftarrow5}2=0.000012$

A suspension bridge with weight uniformly distributed along its length has twin towers that extend 70 meters above the road surf

goblinko [34]

Answer:

17.5 m

Step-by-step explanation:

The height of a parabola above its vertex is proportional to the square of the distance from the vertex.

<h3>Cable height</h3>

The towers are 1200 m apart, so each is 600 m from center. The location of interest is 300 m from center, so 1/2 the distance to a tower. Since the height is proportional to the square of the distance, the height half-way to the tower will be (1/2)² = 1/4 the height of the tower.

(1/2)²×(70 m) = 17.5 m

The height of the cable 300 m from center will be 17.5 meters.
