Answer:

BAKING TINS

Step-by-step explanation:

Use the Pythagorean Theorem to solve = a^{2} +b^{2} = c^{2}.

2) 8² + 6² = c²

64 + 36 = 100

\sqrt{100}

x = 10 = I

3) 10² - 9² = a²

100 - 81 = 19

\sqrt{19}

x = 4.4 = G

4) 8.8² + 3.2² = c²

77.44 + 10.24 = 87.9

\sqrt{87.9}

x = 9.4 = B

5) 27² - 24² = a²

729 - 576 = 153

\sqrt{153}

x = 12.4 = S

6) 11² - 7² = a²

121 - 49 = 72

\sqrt{72} = 8.5

13² + 8.5² = c²

169 + 72.25 = 241.25

\sqrt{241.25}

x = 15.5 = T

7) 22.1² + 14.2² = c²

488.41 + 201.64 = 690.1

\sqrt{690.1}

x = 26.3 = K

8) 32² + 41² = c²

1024 + 1681 = 2705

\sqrt{2705}

x = 52 = N

Hope it helps!

During a scuba dive, Lainey descended to a point 19 feet below the ocean surface. She continued her descent at a rate of 25 feet
Leno4ka [110]

Answer:

25t+19\leq 144

t\leq5

The number of minutes she can continue to descend if she does not want to reach a point more than 144 feet below the ocean surface is <u>at most 5 minutes.</u>

Step-by-step explanation:

Given:

Initial depth of the scuba dive = 19 ft

Rate of descent = 25 ft/min

Maximum depth to be reached = 144 ft

Now, after 't' minutes, the depth reached by the scuba dive is equal to the sum of the initial depth and the depth covered in 't' minutes moving at the given rate.

Framing in equation form, we get:

Total depth = Initial Depth + Rate of descent × Time

Total depth = 19+25t

Now, as per question, the total depth should not be more than 144 feet. So,

\textrm{Total depth}\leq 144\ ft\\\\19+25t\leq 144\\\\or\ 25t+19\leq 144

Solving the above inequality for time 't', we get:

25t+19\leq 144\\\\25t\leq 144-19\\\\25t\leq 125\\\\t\leq \frac{125}{25}\\\\t\leq 5\ min

Therefore, the number of minutes she can continue to descend if she does not want to reach a point more than 144 feet below the ocean surface is at most 5 minutes.

a study timed left-handed and right-handed people to see how long it took them to hit a buzzer. the data is shown below: the six
Effectus [21]

The z or t score to be used is  (0.422,0.978)

How to find the critical value ?

Critical probability (p*) = 1 - (Alpha / 2), where Alpha is equal to 1 - (the confidence level / 100), is the unit statisticians use to determine the margin of error within a set of data in statistics.

The critical value for α = 0.13 is z_{c} = \frac{z_{1} - \alpha }{2}

The corresponding confidence interval is computed as shown below

CI = (X1_{1}  - X_{2}- z_{c} \sqrt{\frac{a_{1}^{2}}{n_{1} } + \frac{a_{2}^{2}}{n_{2} }}  ,  X1_{1}  - X_{2}+z_{c} \sqrt{\frac{a_{1}^{2}}{n_{1} } + \frac{a_{2}^{2}}{n_{2} }}  )

CI = (2.1 - 1.4- 1.514\sqrt{\frac{1^{2}}{37 } + \frac{0.5_{2}^{2}}{38 }}  ,  2.1  - 1.4 + 1.514 \sqrt{\frac{1^{2}}{37 } + \frac{0.5^{2}}{38 }}  )

CI = (0.422, 0.978)

0.422< mu1 - mu 2 < 0.978
