Answer:

The difference in the record high and the record low temperatures is 125°F

Step-by-step explanation:

Given a quantity T that varies in time, say T1 and T2, being T1 the initial value and T2 the final value.

The change or difference between the final and the initial values is:

T=T2-T1

The record low temperature in Pittsburgh, PA is T1=-22°F while its record high is T2=103°F

The difference is:

T=103°F - (-22°F)

Note both negative signs multiply to produce a positive sign, and a sum instead of a subtraction:

T=103°F + 22°F = 125°F

The difference in the record high and the record low temperatures is 125°F

Answer:

4/99

Step-by-step explanation:

Multiply the numerator and den0ominater, then stack them

Answer:

4/99

Step-by-step explanation:

4/9 * 1/11

Multiply the numerators

4*1 = 4

Multiply the denominators

9*11 = 99

numerator over denominator

4/99

Answer:

Leftmost 9: 900

9 between 9 and 0: 90

9 on left is worth 10 times 9 on right.

Step-by-step explanation:

990.250

The 9 at the left is in the hundreds place, so it represents 9 hundreds, so its value is 900.

The 9 between the 9 and the 0 is in the tens place, so it represents 9 tens, and its value is 90.

Since the places are right next to each other, the 9 on the left is worth 10 times the 9 on the right. Sure enough, 900 is 10 times 90.

option 2 i think i hope i am right

Answer:

83.85%

Step-by-step explanation:

The formula for confidence interval

= Mean ±( z × Standard deviation/√n)

Confidence Interval = Mean ± Margin of Error

Mean = 4.20mm

n = 87

Standard deviation = 0.10mm

z = ????

Hence:

Confidence Interval = Mean ± Margin of Error

Step 1

We find the Margin of Error

(4.185, 4.215) = 4.20 ± Margin of Error

4.20 - 4.185 = 0.015

4.215 - 4.20 = 0.015

Hence, Margin of Error = ± 0.015

Step 2

We find the z score

Margin of Error = z × Standard deviation/√n

±0.015 = z × 0.10/√87

± 0.015 = 0.0107211253z

z = ±0.015/0.0107211253

z = 1.39910686428

z score ≈ 1.4

Step 3

We find the confidence interval that corresponds to 1.4

Using the z table to find the Probability

P(z = 1.4) = 83.85%

Therefore, the level of the confidence interval (4.185, 4.215) is 83.85%

Answer:

[4.1mm to 4.3mm]

Step-by-step explanation:

Sample size = 87 glass sheets

Sample mean = 4.2mm

Sample standard deviation = 0.1mm

Confidence interval or level = the range from lower limit of sample mean to upper limit of sample mean

[4.2 - 0.1] to [4.2 + 0.1]  = [4.1mm to 4.3mm]

Answer:

[tex]9 \frac{7}{12} [/tex]

Step-by-step explanation:

Expand:

[tex]6(2x) + 6( - 4) = 7(13) \\ 12x - 24 = 91[/tex]

+24 on both sides:

[tex]12x = 91 + 24[/tex]

Simplify:

[tex]12x = 115[/tex]

÷12 on both sides:

[tex]x = 115 \div 12 \\ x = 9 \frac{7}{12} [/tex]

Answer:

5.3

Step-by-step explanation:

1.8x = 9.4

x = 5.3

The value of x that makes the equation true is 5.3, the correct option is D.

An equation is a mathematical statement formed when two algebraic expressions are equated using an equal sign.

The equations are useful in determination of unknown parameters.

The equation is,

0.3x + 5. 14 = 2.1x - 4.4

The equation is made of two expressions,

The expression 1 is : 0.3x + 5. 14

The expression 2 is : 2.1x - 4.4

The value of x that makes the equation true has to be determined.

0.3x + 5. 14 = 2.1x - 4.4

Grouping the like terms on one side.

5.14 +4.4 = 2.1x -0.3x

Solving the variables and constants

9.54 = 1.8 x

Dividing 1.8 on both sides of the equation.

x = 9.54 /1.8

x = 5.3

The value of x at which the equation is true is 5.3.

Answer:

C, 21:19

Step-by-step explanation:

This is because we know that 21 divided by 7 is 3, so we would have to make sure that we are multiplying 7:3 by 3, which we are because 7 times 3 = 21 and 3 times 3 = 9.

Answer:

6g/mL

Step-by-step explanation:

Given parameters:

Mass of pineapple = 30g

Volume of rise  = 5mL

Unknown:

Density of pineapple = ?

Solution:

Density of a substance is the mass per unit volume. Mathematically, it is expressed as;

           Density  = [tex]\frac{mass}{volume}[/tex]

The volume is the rise in the pineapple drink.

 Insert the parameters and solve;

        Density  = [tex]\frac{30}{5}[/tex]

Answer:

At 19.14 feet the top of the ladder meet the house.

Step-by-step explanation:

It is given that,

A large ladder leans against a house with the base of the ladder 5.8 horizontal feet from  the base of the house.

Slope of the ladder, m = 3.3 feet/foot

We need to find at what height does the top of the ladder meet the house. Let it is h.

Base, b = 5.8 feet

It will form a right angle triangle

Slope=h/base

h = slope × base

h = 3.3 × 5.8

h = 19.14 feet

So, at 19.14 feet the top of the ladder meet the house.

Answer:

Y=2x

Step-by-step explanation:

The complete table is given as follows -

Time (in hours)                        Snow (in inches)

0                                                      1

1                                                       2

2                                                      4

6.5                                                  13

[x]                                                   [2x]

The equation that shows the amount of snow that has fallen after [x] hours can be written as y = 2x

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

The equation of a straight line can be also written as -

Ax + By + C = 0

By = - Ax - C

y = (- A/B)x - (C/A)

Given is that snow Is falling steadily such that after 2 hours, 4 inches of snow has fallen.

In 2 hours → 4 inches of snow has fallen.

Then, in 1 hour → (4/2) → 2 inches of snow has fallen.

So, in 6.5 hours → 2 x 6.5 → 13 inches

Hence, in x hours → 2x inches

The complete table is shown below

Time (in hours)                        Snow (in inches)

0                                                      1

1                                                       2

2                                                      4

6.5                                                  13

x                                                      2x

The equation that shows the amount of snow that has fallen after [x] hours can be written as -

y = 2x

Therefore, the complete table is given as follows -

Time (in hours)                        Snow (in inches)

0                                                      1

1                                                       2

2                                                      4

6.5                                                  13

[x]                                                   [2x]

The equation that shows the amount of snow that has fallen after [x] hours can be written as y = 2x

Step-by-step explanation:

The graph would have a positive y-intercept

The y-intercept is when x = 0

To find the y-intercept, plug in 0 for x

y = -5(0) + 10

y = 0 + 10

y = 10

10 is a positive number

Y-intercept is positive

Answer:
