1998 hurricane Bonnie approached the United States at a speed of 8 miles per hour . The function y= 8x disproves how many miles y hurricane Bonnie traveled x hours . Use the graph to estimate how far the hurricane traveled in 2.5 hours

Answer: (0.0016, 0.1584)

Step-by-step explanation:

Given that:

Mean (m) = 0.08

Standard Error = 0.04

Zcritical at 95% = 1.96

Using the relation :

Mean ± Zcritical * (standard error)

0.08 ± 1.96 * (0.04)

Lower boundary = 0.08 - (1.96 * 0.04)

Lower boundary = 0.08 - 0.0784 = 0.0016

Upper boundary = 0.08 + (1.96 * 0.04)

Upper boundary = 0.08 + 0.0784 = 0.1584

Confidence interval is Hence,

(0.0016, 0.1584)

The 95% confidence interval is given by (0.0016 , 0.1584) and this can be evaluated by using the mean and standard error relation.

Given :

To determine the 95% confidence interval using the following relation:

[tex]\rm \mu \pm z_{critical}\times standard \;error[/tex]

[tex]0.08\pm 1.96\times 0.04[/tex]

So, the lower and upper boundary is (0.0016 , 0.1584).

Therefore, the 95% confidence interval is given by (0.0016 , 0.1584).

Answer:

39.60

Step-by-step explanation:

9.90 x 4 = 39.60

The coefficient of the variable y for the given equation 4 - 2y is -2.

A coefficient is a number that is being multiplied by the variable, i.e. the numerical term with variable, that is a number that is placed before another variable. While the variable represents some quantity, it may also represent a number, a function, etc. The letters a, b, c, x, y, and z are common symbols used for variables.

We have,

An equation 4 - 2y,

So,

In the above-given expression,

We have only one variable and one Constant term,

i.e.

Constant term = 4

And,

Variable term = -2y

So,

In the variable term,

The coefficient of y = -2

So,

The coefficient of y is -2.

Hence, we can say that the coefficient of the variable y in the given equation is -2.

Answer:

The correct answer is £72 by WeGoFast and £80 by ParcelsFly

Step-by-step explanation:

Hector wants to send a parcel to Spain.

Dimension of his cuboid parcel is 10 cm by 10 cm by 40 cm.

Sum of the three dimension in cm = (10 + 10 + 40) cm = 60 cm.

Volume of the parcel in  = (10 × 10 × 40)  = 4000.

Price charge by WeGoFast = Sum of the three dimensions in cm × £1.20

= £ (60 × 1.20) = £72.

Price charged by ParcelsFly = Volume measured in  × £0.02

= £ (4000 × 0.02) = £80

Answer:

Step-by-step explanation:

3x + x + 60 = 180.

first, we add the x's together.

4x + 60 = 180

then we see if they all have a common multiple. in this case, they do. they are all divisible by 4, so we can use that.

x + 15 = 45

then, just subtract 15 from both sides, that way we get the variable by itself.

x = 30

also, it is a right triangle. the top angle (3x) multiplied by 3 is 90. any triangle that has a 90 degree angle is automatically a right triangle.

Step-by-step explanation:

3x+X+60=180

4x=180-60

X=120/4

X=30

Answer:

It is not a function.

Step-by-step explanation:

A relation can only be a function if every input (x-value) of the set of values of the relation, has exactly one output (y-value).

In the relation given, one input, -2, has two output related to it, 5 and 0. That's (-2, 5) and (-2, 0).

Therefore, the relation is not a function.

Option C

Step-by-step explanation:

Given inequality is,

5x + 38 ≤ 4(2 - 5x)

5x + 38 ≤ 8 - 20x [Distributive property]

5x + 20x + 38 ≤ 8 - 20x + 20x [By adding 20x on both the sides of the inequality]

25x + 38 ≤ 8

(25x + 38) - 38 ≤ 8 - 38 [By subtracting 38 on both the sides of the inequality]

25x ≤ -30

[tex]\frac{25x}{25}\leq -\frac{30}{25}[/tex] [Dividing by 25 on both the sides of the inequality]

x ≤ 1.2

Therefore, Option (C) will be the correct graph.
