Animal scientists studied foraging behavior of the scrub lizard, found in central Florida. Foraging is the process of searching for food. To study such behavior, the scientists recorded the number of head movements per minute for a sample of 63 lizards. A 95 percent confidence interval constructed from the sample is given as 2.7±0.62 head movements per minute. Based on the interval, is a claim of 3 head movements per minute plausible?

Answer:

It could be =15 or =0

Step-by-step explanation:Multiplying each side of −3x+4y=20

by 2 gives −6x+8y=40

. Adding each side of −6x + 8y = 40 to the corresponding side of 6x+3y=15

gives 11y=55,ory=5

. Finally, substituting 5 for y in 6x+3y=15

gives 6x+3(5)=15,orx=0

.

Answer:

x-3y=15 has a y-intercept of -5

Step-by-step explanation:

A y-intercept occurs when x = 0. So, when x = 0, which function has a y-value of -5?

Plug in 0 for all the values of x and solve for y.

1. 2(0)+y=-10; y=-10

2. (0)-y=-5; y = 5

3. (0)-3y=15; y = -5

4. -(0)+4y=20; y= 5

Answer:

68%

Step-by-step explanation:

The Empirical rule formula is given as:

68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ .

95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .

99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ .

Where

μ is the population mean

σ is the population standard deviation.

Step 1

Find the number of standard deviations from the mean

μ - xσ and μ + xσ

μ = 175

σ = 13

For 162

175 - 13x = 162

175 - 162 = 13x

13 = 13x

x = 13/13

x = 1

For 188

175 + 13x = 188

13x = 188 - 175

13x = 13

x = 13/13

x = 1

Hence, the data falls with 1 standard deviation of the mean

Therefore, percentage of the games that Mayerlin bowls does she score between 162 and 188 is 68%

The circle is centered at (−2, 4) and has a radius of 15.

i took the test

A circle represented by the equation (x+2)² + (y - 4)²= 225 is centred at  (-2,4) and has a radius of 15.

The equation of a circle is represented as follows:

where

(h, k) = centre

r = radius

Therefore, (x+2)² + (y - 4)²= 225 has the following centre and radius.

Then

(h, k) = (-2,  4)

Therefore, the circle is centred at (-2,4) and has a radius of 15

Answer:

Step-by-step explanation:

Infinitely many solutions means that one side of the equals sign is exactly the same as the other side. We can achieve that easily by multiplying through the parenthesis and then combining like terms.

2(6x + 4) - 5x is 12x + 8 - 5x which simplifies down to 7x + 8. That is what goes on the right side of your equation.

Answer:

x = 6

Step-by-step explanation:

Use the Intersecting chord theorem;

Rule: (CE) * (EB) = (AE) * (ED)

CE = x

EB = 15

AE = 9

ED = 10

=> (x) (15) = (9) (10)

15x = 90

Now Divide each side with 15

=> x = 6

The number of years it will take until the stalactite is 1 meter long is; 70 years

From conversion units, we know that;

1 m = 100 cm

1 cm = 100 m

Current length is given as 72 cm

Thus;

Length after x years = 1 m = 100 cm

Length increase in x years  = 100 -72 = 28 cm

Since 1 cm = 10 mm

Then;

Length increase in x years  in mm = 28 * 10 = 280 mm

Thus;

Length increase in 1 year = 4 mm

Length increase in x years = 4x mm

Then; 4x  = 280

x = 70

Thus, it will take 70 years  until it is 1 meter long.

Agree: when Asher looks at the data, he says that both Mrs. Jamisos class and Mr. Zimmermann's class has data that is skewed right.

It is defined as the numerical data representation in the graph with the help of a bar without space. The histogram gives an idea about the data's approximate distribution.

We know on the left side skewed histogram has more data on the right and on the left side, there are fewer data. It is also called a negatively skewed histogram.

On the right side skewed histogram, there is fewer data on the right side and more data on the left side. It is also called a positive histogram.

As we can see in the histogram of Mrs. Jamisos class and Mr. Zimmermann's class, there is fewer data on the right side, hence it is right side skewed.

Thus, agree: when Asher looks at the data, he says that both Mrs. Jamisos class and Mr. Zimmermann's class has data that is skewed right.

Answer:

a) 5units

b) (4.5, 4)

Step-by-step explanation:

Let the coordinate of P and Q be P(3, 2) and Q(6, 6)

PQ can be gotten using the distance formula;

PQ =√(6-2)²+(6-3)²

PQ = √4²+3²

PQ =√16+9

PQ =√25

PQ = 5units

Midpoint M is  expressed as;

M(X, Y) = {(x1+x2)/2, y1+y2/2}

X = x1+x2/2

X = 3+6/2

X= 9/2

X = 4.5

Similarly;

Y = y1+y2/2

Y = 2+6/2

Y = 8/2

Y = 4

Hence the midpoint of PQ is (4.5, 4)

Answer:

x = 2

y = -3

Step-by-step explanation:

2x + 2y = -2, then 2y = -2 - 2x

3x - 2y = 12, then 2y = 3x - 12

so:

-2 - 2x = 3x - 12

add 2x and 12 to each side of the equation:

5x = 10

divide both sides by 5:

x = 2

2y = 3(2) - 12

2y = -6

divide both sides by 2:

y = -3

Answer:

147.7 m²

Step-by-step explanation:

Area of the triangular faces = 1/2 × base × height

A triangular pyramid has lateral faces with bases of 8 meters and heights of 10 meters.

Hence: 1/2 × 8 × 10 = 40 m²

A triangle has 3 faces, hence, area of the 3 faces = 3 × 40 m²

= 120m²

The area of the base of the pyramid is 27.7 square meters.

Hence, the surface area of the pyramid is calculated as:

Area of the 3 lateral faces of the pyramid + Base area

= 120m² + 27.7 m²

= 147.7 m²

The surface area of the pyramid is 147.7 square meters.
